By using water as a commodity, we are using up the fresh water the planet provides faster than it can replenish it.

Back in 2007, Dr. Farrington, the Executive Director at the California Academy of Sciences took a step toward sustainability by banning water bottles at meetings and functions, noting that bottled water is expensive, wastes plastic, and is harmful to the environment.  Since then, bottled water has been banned at private functions and in the Academy café – glass bottles are available but not plastic ones.  At NightLife, water is dispensed in compostable cups.  I am in further support of this decision after recently watching the documentary Blue Gold: World Water Wars.

Blue Gold is a documentary that focuses on the controversy that has arisen by the marketing and privatization of water.  The planet provides a cycle to provide fresh water. To begin, water in the oceans and in caches of ice and snow are heated by the sun and evaporate.  This water vapor is then carried into the atmosphere and condenses into clouds.  Clouds migrate through the sky, collide and grow.  Some of these cloud particles then fall as precipitations in as rain snow or ice.

This water then either falls back into the ocean or onto land.  Some of it accumulates into snow packs or glaciers.  A fraction of it enters streams or rivers and flows back to the ocean.   Some water seeps into the ground and becomes ground water.  Part of groundwater stays close to the surface and nourishes and replenishes topsoil.  Ground water can also seep deep into the ground and create a water cache in saturated subsurface rock; these catches are known as aquifers.  This water cycle is constantly replenishing and provides the freshwater for all life on the planet. A great chart and break down of this cycle is provided by USGS.

Blue Gold touches on how this cycle is getting interrupted.  For example, in cities ground water cannot seep into the ground through the concrete to create aquifers.  So most of the run off goes directly back to the ocean.  Thus most cities must cart fresh water from far away; water is most often pulled out of aquifers, which creates a desertification of once fertile land.  Without the ground water, soils dry out and cannot sustain the fertility of the plants and trees creating a dessert environment.  Streams and rivers in a natural cycle will push sediment and nourishment into the land surrounding them.  Much like blood is a super highway in our bodies, streams and rivers act like the vein and arteries of the Earth.  Huge dams used to harness power and provide drinking water have dried up these rivers and the subsequent land around them.

With the interruption of this cycle scarcity has emerged.  One of the biggest culprits of this scarcity is treating water like a commodity rather than a natural resource. Today, this has been seen prominently in third world countries where agricultural goods and water are being exported.  In Bolivia, a civil war broke out because a private company owned the water, including rainwater.  People could not pay for the water needed to survive and fought back.  More about the conflict is outlined in the following article.  By using water as a commodity, we are using up the fresh water the planet provides faster than it can replenish it.

So what can people do to help combat this scarcity?

-       Do not buy or drink bottled water.  The water is being sapped from aquifers, lakes and streams.  By doing so, that water cannot be replenished back into the natural water cycle.

-       Buy locally.  When you buy produce from far away, water is often being exported to grow that produce.  By buying locally, less water is being used for the products used.

-       Use a low flow showerhead or toilet at home.

-       Turn off the water when you are brushing your teeth.

-       Look into charities that provide water for those in third world countries.  (Many people are being charged prices they cannot afford for metered water). Two great programs are Ryan’s Well Foundation, which is noted in this documentary and Play pumps that harness the energy of kids playing on a merry-go-round to pump water.

Pepin is famous for going to work after just 9 weeks of training, finding 52 scats in a single day.With unemployment at an all time low, it seems controversial that some very solid jobs are going to non-humans, but there are just some things that humans will never be qualified to do. Unfair, you say? Well, let’s run down the list of job requirements for this specific position and if you can find a human that qualifies, reply at once.

This candidate must:

• Follow orders
• Be rough, energetic and adventurous
• Travel around the world
• Find things that are nearly impossible to see
• Be willing to ride in the back of a truck and wear a collar
• Run long distances
• Be a fast learner
• Be obsessed with toys
• Be willing to sniff poop
• Get compensated in rope-tugging with benefits such as scratches and belly rubs
• Come from a background of animal shelter living

Yes, the only qualified species is: Dog.

The Job: Working Dog for Conservation.

I saw these dogs in action at the Wildlife Conservation Network (WCN) Expo in San Francisco in October. The organization, Working Dogs for Conservation and their dog demo with Pepin took center stage during lunch. While Pepin was inside the building schmoozing with the likes of Dr. Jane Goodall, her trainers hid scat in a giant, wide open field area. Once the crowd gathered, Pepin was taken outside, given directions and once released, blasted with determination and blatant glee out into the field. Within 3 minutes she had located the scat and sat proudly next to it, indicating to her trainer that she had done her job; a job that would have taken a human hours.

Being able to find scat helps humans track down various species in the wild and provides needed species conservation information. Deployed conservation dogs have increased scat sample collection rates and have discovered samples that are smaller and more cryptic than people alone are capable of detecting. The working dogs for conservation have found scat of moose, snow leopard, grizzly bear, wolf and cougar, to name a few. The dogs have also been trained to find plants and lost pets and people.

Partnering with dogs is nothing new. Humans have been using the 220 million scent-sensitive cells available for canine olfaction for centuries. These animals are truly man's best friend, but perhaps they are becoming nature's best friend, as well. They certainly deserve to hold this most unusual job.

What would it take you to change your shower to a low-flow shower head?

Do you love a long, hot and powerful shower? What would it take you to change your shower to a low-flow shower head? Be honest.

• A. I understood the environmental impact that it would have
• B. I have knowledge of and compassion for the watershed
• C. Someone came to my house and put in a free low-flow shower head for me
• D. I would be publicly recognized
• E. I verbally committed to doing it
• F. Everyone else on my block is doing it
• G. President Obama and Jane Goodall are doing it (not together!)
• H. All of the above.

Canadian environmental psychologist Doug McKenzie-Mohr believes that the last five reasons inspire more behavior change than the first two. I recently took a workshop with McKenzie, who coined the phrase “Community Based Social Marketing”, and was amazed to learn that studies indicate that “information intensive” campaigns are not very effective. Uh-oh – time to recycle the brochures. This is the method that we have been using to influence behavior change for years.

An earlier blog of mine explored what makes a person care about nature. Now I’m compelled to explore what makes a person change a behavior for the good of nature – the outcome I ultimately desire. Perhaps Community Based Social Marketing (CBSM) is the answer.

CBSM believes that people do not change behavior or do an activity because:

• They do not know about it
• They have many perceived barriers to the activity
• They believe it is easier to continue to do their current behavior than to change

Once the targeted audience knows about the issue, and the barriers are identified with research, it is time to convince them that the benefits outweigh those barriers.

There are many tools for inspiring the change of behavior: making a commitment, copying a well-respected community leader, being reminded with prompts, realizing that the behavior is the current social norm, clear and vivid messages, incentives, ease or a combination of these concepts. CBSM also believes that requests to change behavior are the most effective when they are at the community level and involve direct contact with humans. At the end of the program, outcomes are measured, not outputs. This makes sense!

So, with this in mind, what if President Obama and Dr. Jane Goodall arrived at your door with a lovely, low-flow shower head and installed it while they told you all about the watershed and how you are helping. They then planned to install an identical shower-head in all your friend’s bathrooms followed by thanking you all in the local newspaper. Would you change your showering behavior then? I think I would – a victim to the new concept of Community Based Social Marketing.

I can’t wait to try to get influence our zoo public to compost, our staff to recycle, and my supervisor to send me to more of Doug McKenzie’s workshops. And I will await that knock on my door.

The National Parks are a living record of America's past.

Living here in the San Francisco Bay Area I marvel at the diverse culture that sprouts from our surrounding parks and open spaces. In Golden Gate Park alone you can practice fly-fishing, sail a model boat, ride a horse, play golf, kick a soccer ball, tackle rugby, or pitch a horseshoe, bocce or baseball. You can see where the buffalo roam or spin round and round on an antique carousel. Skate, bike, row a boat, play music, dance to the beat of your own drum and stop to smell the roses. Nearby, down at Ocean Beach surfers ride the waves and kids make sand castles. Stroll the promenade at Crissy Field and you’ll see people soaking up the sun on the beach, flying kites, fishing off the pier or windsurfing under the Golden Gate. Go to Fort Funston where you can run your dogs down to the beach or launch your hang glider off the cliff and soar into the sky. I can go on and on but you get the picture. And that’s just here in San Francisco! Add the Peninsula, North, South and East Bay then combine all the city, county, state and federal parks with all the regional open spaces and count your blessings. It’s been said that if you go to any neighborhood in Bay Area, there is a park or a trailhead less than a mile away. These places are calling us outside to play. And in the process they are building our communities, and in many ways defining who we are and who we want to be.

Of all the activities happening in the parks, probably the most important and rewarding is volunteering to help preserve and protect these amazing places. I urge you all to pitch in. Contact your local regional parks and open space district and see what you can do to help. It’s up to all of us to make sure these wonderful places are saved and maintained for everyone in the future.

If you've watched the show, or are reading this blog about the National Parks, the chances are you also know that filmmaker Ken Burns is about to release his next series "The National Parks: America's Best Idea." Through our role in the development and distribution of the series, KQED is collecting viewer stories about their own experiences with these hallowed places. Let us know what these marvelous open spaces mean to you by sharing your story. We’d love to hear about your favorite park, Bay Area or beyond.

Every fall, 30,000 raptors and hawks migrate across the Bay Area in a fantastic display.Every fall, 30,000 raptors and hawks migrate across the Bay Area in a fantastic display. Most stop for a quick snack in the Marin Headlands before moving on to their winter homes. Bay Area scientists and volunteers have been using the opportunity to conduct counts, as raptors have long been seen as indicators for ecosystem health. The Golden Gate Raptor Observatory, now a program of the Golden Gate Parks Conservancy, was set up 25 years ago as the first bird monitoring system in California. Anyone that visits “Hawk Hill” during this time can attest to mass migration; Upwards of 1000 birds are seen per day during the peak. To my amazement, the observatory is almost fully run by volunteers; there are only 3 full time employees compared to over 300 volunteers. Clearly, this is one of the most successful citizen science projects in the Bay Area.

In celebration of the 25^th anniversary, there are a number of interactive events and talks scheduled over the next month.

get tac redits and rebates for doing the right thing? What could be better? Image source: Mark_WIt's a good time to get energy efficient at home, what with a down economy and efforts by federal, state and local governments, and utilities to decrease our overall energy use and create a new, more secure, job-creating green economy.

Top Five Federal Tax Credits (for improvements made from January 1, 2009 through December 31^st, 2010)

1.      Adding qualifying insulation to an existing home-30% of cost, up to $1,500 for all upgrades other than renewable energy systems.

Before You Invest in Photovoltaics, make sure your house isn't haunted by phantom loads.Some Devices Suck Power While They Sleep

When writing about energy efficiency in California, I know that emphasizing heating systems doesn’t carry much punch. I might as well try to get Californians interested in who makes the best deep- dish pizza. (That’s Chicago, of course. Zachary’s isn’t bad though.) Cooling systems are accounting for more and more of a share of residential energy use as we continue to build out from the cities near the Bay in hot dry climates. But overall, when it comes to climate, the inside and the outside of Bay Area homes are pretty much the same for most of the year. But let’s not get soft on energy efficiency! There are other energy users in California homes that threaten to lift us in the future to the level of, say, what a Wisconsin home uses in the winter today.

Miscellaneous electric loads are electric loads other than heating and cooling, water heating, refrigerators, and lighting, and include consumer electronics, outdoor lights, and portable inside lighting fixtures. The U.S. Department of Energy’s Energy Information Agency estimates that these “other” electric loads, along with televisions and office equipment, made up close to 30% of U.S. residential electricity consumption in 2006; this will rise to about 35% by 2020. Part of the reason for the growth in energy use of these devices as a percentage of total home energy use is that homes are heating and cooling more efficiently, with better HVAC equipment, tighter building envelopes, and more insulation.

Rich Brown and Greg Homan of Lawrence Berkeley National Laboratory, measured electricity use in 13 new California homes in 2007 and came up with some interesting results. They metered plug-in devices in standby, off, or low-power mode. Since the homes were not yet occupied, they estimated the annual energy use by using typical use patterns and the energy use of the plug-in devices in active mode, or “on,” measured in other studies. Some of the homes were model homes and packed with appliances and electronics like TVs, and others had only the plug-in devices installed by the builders. Builder installed devices include things like garage door openers, structured wiring, and gas fireplaces. The homes were in four different subdivisions and span the range of typical new construction to super efficient homes with PhotoVoltaic (PV) systems installed.

The builder-installed devices use on average 800 kilowatt-hours (kWh) of electricity per year, or about $80 worth with electricity at a low $0.10 per kWh. That does not include lighting energy. That’s interesting. About half of the energy used by the builder-installed devices is used by devices that are supposed to be turned off, or are in standby mode! That’s very interesting. This is like having a 50-Watt light bulb on 24 hours a day, 365 days a year, lighting nothing.

One of the model homes, the biggest energy user of the 13, used close to 2,500 kWh per year ($250) for two large televisions, a structured wiring panel that uses 20 Watts continuously to power three security cameras and an Internet router, smoke alarms, garage door openers, a washer/dryer, a very big refrigerator, and a few more devices. Add in lighting and that house is a major energy hog, even with super efficient heating and cooling systems and PV panels on the roof.

So what to do? Don’t even think of getting that PV system until you spend some time reducing your electricity load. The PV system you need to meet that load then won’t be so expensive. When it’s time to buy a new appliance, always look for the Energy Star label. Energy Star appliances use about 20% less energy than typical new appliances. Anything that uses a remote control, such as televisions and set-top boxes, or that displays the time of day all day, such as some stoves and microwave ovens, uses energy when officially off. Look for electronic devices that are really off when they say off, or that use 2 Watts or less in standby mode. For your other sleep slurping electronics, plug them into a power strip, and turn the power strip off when you aren’t using the devices. Then look into that sexy new PV system for your roof. More on that in my next blog.

This attic hatch insulation kit install is making the author use some choice language.My attic hatch insulation kit came in the mail this morning and I am very excited. Excited enough to go into a hot dusty attic to install it over the weekend.

I promised Michele that I will practice the Yoga of home improvement projects and keep the cursing down to a minimum. My home improvement projects usually involve some cursing. I worked part time as a janitor when I was in high school and that's when I learned some pretty spicy language. I didn't intend to write about cursing here, but since I am in this so deep now, then damn it, I may as well connect the topic to some cutting edge scientific research. You got a problem with that?

British scientists found that cursing takes away pain. When people put their hands in a tub of cold water and cursed, they could hold their hands in longer than if they said things like, "butterscotch." If you don't want to take my word for it, you no-good so-and-sos, the research results were published in the online journal NeuroReport.

The attic hatch insulation kit will save us some energy losses and utility bill pain in the long run. According to the DOE Weatherization Assistance program, a gosh darn uninsulated 10 square foot attic hatch in a 100 square foot insulated attic can decrease the overall R-value of the attic floor by more than 50%! For example, an attic with R-38 insulation everywhere but on top of a stinking quarter-inch plywood hatch-with an R-value of approximately 0.3-will have an overall R-value of only R-17. What a freaking waste! Bloody hell!
You can find out more about insulating attic hatches at the Department of Energy's Energy Efficiency and Renewable Energy Web site. Do it now!

Ain't love grand? Once courtship and mating are over, the female hornbill finds a tree hollow and seals herself in with dung, fruit and pellets of mud.

I love our hornbills. Situated in the Rainforest section of the Zoo, between our gibbons and our chimps, they are often overlooked, yet I find them fascinating.

The female has the bright blue gular pouch (an expandable throat sac, used for short-term storage of food) and the male has the pale yellow version.  Like all hornbills, they have a distinctively large and down-turned beak.  These Malayan Wreathed Hornbills are one of the 54 species found in Asia and Africa.

Their dramatic nesting ritual is what makes them so interesting. Once courtship and mating are over, the female finds a tree hollow and seals herself in with dung, fruit and pellets of mud. The male gathers the pellets from the forest floor and swallows them, later regurgitating small saliva-cased building materials. He then gives them to the female who stays inside the nest leaving a slit for a window big enough to receive food and materials. For the next 6-8 weeks the male feeds the female through this opening. She does not emerge until she has molted and re-grown fresh feathers and her young has grown and become feathered, as well. Then, both mother and child knock down the wall and appear on the scene, happy and healthy. Last year the public was enthralled, as our hornbills participated in this ritual.

The zoo is concerned with the status of hornbills in the wild, and since 2004, the Oakland Zoo Conservation Fund has worked with a fantastic program coordinated by the Hornbill Research Foundation. Besides collecting data, the foundation has launched a Hornbill Nest Adoption Program, which works to foster conservation of these beautiful birds. Illegal logging and the poaching of young birds for the pet trade are the key issues facing hornbills. The Nest Adoption Program employs local people to look after the hornbills in their nests and collect scientific data about them.

When you adopt a nest, you get a wonderful pamphlet of information about the hornbill, a map of the location of your particular nest, a profile of your guard and, my favorite, a break down of what food the male brought to the female (2 figs, .3 millipedes, 1 lizard).

This summer, eighteen Oakland Zoo teens and staff will embark on a journey to visit Thailand and will spend a day at Khao Yai National Park with the intention hope to spot birds, nests and learn first hand about the project.  They will also visit with the Young Bird Conservation Club, which creates Hornbill art to sell to zoos for their Conservation Projects. To prepare for their trip, these inspired have been attending workshops and raising funds to adopt two nests of their own.

Back at the zoo, the summer will be filled with more hornbill conservation action as ZooCamp 2009 has adopted the species as their official summer animal. With a hornbill on the front of their t-shirt and the Hornbill Research Foundation logo on the back, all campers will be learning about this animal and the project that supports them. Each camper has also contributed a bit of their camp fee into the program and will surely leave camp with the contribution of knowledge and compassion for these incredible birds.

Come by and visit our hornbills, join us this summer at ZooCamp ,or adopt a nest yourself (http://www.zoo.org/conservation/hornbill.html).

Who's more energy efficient with the dishes– you or your dishwasher? Image: Ronan_tlvA microwave oven is the most efficient way to heat water for a cup of tea, hot chocolate, or coffee. True or False?

Now as a regular morning coffee drinker who uses a kettle and a gas stove to heat water for coffee (not instant– yuk! I use a coffee filter cone and PEET's coffee, of course) instead of the microwave, since our microwave is an old piece of inefficient junk that takes forever to heat water, I thought that buying a new microwave would make me a more energy efficient coffee drinker. But I was wrong!

Jennifer Mitchell-Jackson, while a graduate student at Lawrence Berkeley National Laboratory, measured the energy use of an average microwave oven, an electric stovetop, and a gas stovetop to heat up a mug of water. Turns out that an electric stove uses 25% less electricity than an average microwave oven to heat a mug of water. A gas stove is less efficient and uses more energy than a microwave oven, but depending on the cost of gas, it might cost less to heat a mug of coffee with gas compared to the microwave.

It is more efficient to wash dishes by hand than it is to use a dishwasher. True or false?

How many arguments has that one caused! The research to dispel this myth came from Germany. Rainer Stamminger, a professor of household and appliance technology and his colleagues at the University of Bonn, gathered more than 100 volunteer dishwashers with varying skill levels and dishwashing styles in a laboratory, and measured the amount of water and energy each used to wash big stacks of dirty dishes. He then washed similar dirty dishes in dishwashers and measured the dishwashers’ water and energy use.

His conclusion: The machine is more efficient than the hand. In general, the dishwashers used much more water and somewhat more energy than the dishwashing machines. Some test subjects used 53 gallons of water to clean 12 place settings! But there is a wide variation in the styles and economics of hand dishwashing.

Clearly, a new, efficient dishwasher is best. But if you can’t afford one, or like to spend a lot of time with your hands in soapy water, Stamminger and company have some suggestions:

• Remove large dish scraps with a fork or spoon.
• Do the dishes soon after a meal before the food has dried on the plates (get your dinner guests involved).
• Do not pre-rinse your dishes under running tap water (same goes for dishwasher use).
• Use a hot-water sink for washing and a cold-water sink for rinsing.
• Use just the amount of detergent recommended by the manufacturer.

And put that coffee mug in the dishwasher when you're done.
