My father was ahead of his time.
Years before Americans were asked to, Jim Hayden ensured that our family conserved energy by keeping the thermostat low, turning off lights and taking "military" showers to reduce water use. My father also observed the speed limit. Our family vacations took us to national parks. I grew up with a keen appreciation for the outdoors. I remember the sense of horror and helplessness when I saw the images of distressed wildlife in the aftermath of the Santa Barbara oil spill, which devastated the beaches that were an important part of our family's life.
In part as a result of that oil spill, Earth Day came into being. And 49 years after that inaugural Earth Day event, many of us will find ourselves at a gathering dedicated to increasing awareness of the environment that supports and sustains us all.
History of Earth Day
Earth Day was launched in 1970. Many factors contributed to the call for a national day focusing on environmental stewardship, including the publication of Rachel Carson's Silent Spring - serialized in the New Yorker - and the catastrophic oil spill that occurred off the coast of Santa Barbara in 1969. The Santa Barbara oil spill galvanized U.S. Senator Gaylord Nelson (D-Wisconsin) to call for a national day of locally inspired and organized "teach-ins" on the environment - a national "Earth Day." The Earth Day model was inspired by the spirit of campus activism at the nation's colleges and universities. It wasn't top-down, but rather a grassroots effort that encouraged communities to develop educational and service events around issues and topics important to them.
Earth Day struck a chord; some estimates suggest that 1 in 10 Americans participated in the first events. Earth Day is widely credited with "sparking" the modern environmental movement. Landmark environmental legislation swiftly followed (including the Clean Air Act, Clean Water Act and Endangered Species Act). The Environmental Protection agency was founded that same year. Twenty years after its launch, Earth Day became a global movement.

UC ANR research efforts support a healthy and sustainable environment
UC ANR is dedicated to supporting a healthy and sustainable environment. It's part of our core mission. Highlighted below are just a few of the many projects we're working on to protect California's natural resources, build climate-resilient communities and ecosystems, and promote healthy people and communities.
Seeking Street Trees that Can Cope With Climate Change
Trees play a vital role in shading and beautifying California's urban areas. UC ANR researcher Janet Hartin says that:
“Urban areas create heat islands, with dark asphalt surfaces reradiating heat. Cities can be 10 to 20 degrees warmer than the surrounding environment."
Trees provide other benefits, including improving soil health and stability, providing habitat for wildlife and serving as a source of beauty. But climate change (resulting in reduced rainfall and higher temperatures) can create chronic stress in some street tree species.
To find a solution, UC Cooperative Extension scientists are partnering with the U.S. Forest Service "in an unprecedented 20-year research study to expand the palette of drought-adapted, climate-ready trees for several of the state's climate zones."
“The idea is to look at available but under-planted, drought-tolerant, structurally sound, pest resistant trees for Southern California that do well in even warmer climates,” said Janet Hartin, UCCE horticulture advisor in San Bernardino County.

CDFA and UC ANR join forces to advance Climate-Smart Ag
A new partnership between the California Department of Food and Agriculture (CDFA) and UCANR aims to advance climate-smart ag in California. More than $1 million has been used to hire 10 UC Cooperative Extension community education specialists, who are being deployed to 10 counties to help farmers participate in CDFA programs that increase the adopting of "smart" farming and ranching practices.
The primary focus is putting into action on-farm solutions to improve (and increase) smart farming practices that reduce greenhouse gas emissions. Practices that improve soil health, nutrient management, irrigation management, and more will be emphasized.

Be kind to the Earth by reducing food waste
Nearly 40 percent of the food produced in the U.S. is wasted and much of that waste ends up in landfills (definitely not good for our environment or the economy). The National Resources Defense Council estimates that the average family of four throws out nearly 1,000 pounds of food each year, wasting roughly $1,500. Consumers as a group waste more food than farms, grocery stores or restaurants. For tips on ways you can reduce #FoodWaste, click here.

4-H Sustainable You! summer camp to be offered in Ventura County
The UCCE Ventura County team will once again be hosting its week-long 4-H Sustainable You! summer day camp at UC's Hansen Agricultural Research and Extension Center (HAREC) in Santa Paula. Campers aged 9-12 are invited to spend time on a working farm, learning what it means to be sustainable through fun activities based around the five major themes: Air, Land, Energy, Water, and Food. Registration information can be found here.
For more than 100 years the UC ANR 4-H Youth Development Program has taught generations of California children about food, agriculture, leadership, and community service using learn-by-doing practices. The California 4-H Science, Engineering and Technology (STEM) Initiative seeks to increase science literacy and help address the growing need for scientists, engineers, and technical experts. 4-H empowers youth with the skills to lead for a lifetime.

The above photo is one of my favorites. It was taken by Apollo 8 astronaut Bill Anders on Dec. 24, 1968, while in orbit around the moon. It shows the Earth rising for the third time above the lunar horizon. It always serves to remind me that my individual actions do matter, and when considered with the actions of others, contribute to real change ... the "moon shot." Have a great Earth Day!/h3>/h3>
When people don't think about the impact of their decision-making on others, it can ultimately lead to tragedy - the tragedy of the commons, said UC Agriculture and Natural Resources researcher Mark Lubell during an interview on Jefferson Public Radio. Lubell, director of the Center for Environmental Policy and Behavior at UC Davis, studies human decision-making in the context of the environment.
"People think about what happens on their private land and make their private decisions, but they don't think about how their private decisions affect others," Lubell said. "You see this all the time with human decision-making."
An example he uses with his students is how they and their roommates manage their shared kitchens.
"When one person's dishes pile up, it impacts the others," Lubell said. "I ask how they would make rules to solve the problem."
Lubell said the parties need to collectively develop a policy that is mutually beneficial.
"If we didn't have that capacity, we would be in big trouble," Lubell said.
Cooperation tends to be the norm, however the media is more likely to cover cases of conflict, so they tend to get more attention.
The primary goal of PLT is to teach people how to think, not what to think, about complex environmental issues. This has been the vision of PLT since the mid-1970s, inspiring educators to teach and students to learn about their environment, by doing.
At the outdoor workshops, foresters demonstrate forest practices and talk about forest science. For example, Mike De Lasaux, UC Cooperative Extension forestry advisor in Plumas and Sierras counties, leads participants out to take tree measurements and shows them how foresters determine the age of a tree by taking a core sample and counting the rings.
“The program is designed for teachers and other educators, parents and community leaders who work with youth from preschool age up through grade 12,” said Sandy Derby, UC Cooperative Extension statewide coordinator.
Recognized as a leader in environmental education for more than 35 years, the program started by the American Forest Foundation enhances critical thinking, problem-solving and effective decision-making skills, Derby said.
How does it all work? Project Learning Tree collaborates with a network of more than 200 facilitators, natural resources professionals and researchers across the state to provide three types of trainings: educator workshops, training with the Forest Institute for Teachers and train-the-trainer workshops.
Project Learning Tree's educator workshops are six to eight hours on one or more days and offered at UC ANR Research and Extension Centers located around the state. They focus on introducing the goals and vision of teaching and learning using PLT best practices. Each educator receives a PLT guide for use in the classroom.
After taking the PLT educator workshops, graduates can take a two-day training to learn how to train others. Train-the-trainer workshops are offered a few times each year in different locations.
Project Learning Tree in California was delivered by CALFIRE for 25 years before becoming part of UC Cooperative Extension. In 2013, under UCCE advisor De Lasaux's guidance, Project Learning Tree was brought into UC Cooperative Extension to create more collaborative partnerships, engage more natural resources professionals and to expand the number of educators trained to use PLT materials.

Scientists from 25 countries will gather on the Monterey Peninsula to discuss “Plants and the Changing Environment” in June. The 9th Air Pollution and Global Change Symposium will be held June 8-12 at the Asilomar Conference Center in Pacific Grove.
The goal of the series is to consider interactions of air pollution and global change and their impacts on vegetation.
“The symposium is unique in dealing with effects at all levels from molecular and cellular mechanisms, whole plant and crop impacts, all the way up to models of ecosystem and regional impacts,” said David A. Grantz, UC Cooperative Extension specialist based in the Department of Botany & Plant Sciences at UC Riverside.
The symposia are held every few years in different countries, the last in Groningen, The Netherlands, in 2011. The event in California is being organized by Grantz and Kent O. Burkey, USDA/ARS plant physiologist and North Carolina State University professor of crop science and botany in Raleigh.
UC scientists and students engaged in research on the interactions of plant function, metabolism and communities with environmental pollution and global change are encouraged to attend.
“This is an important opportunity for U.S. scientists because the last time this symposium was held in the U.S. was in 1992,” said Grantz. “This is a great chance to catch up on the physiological ecology and modeling efforts underway in Europe and Asia.”
The confirmed keynote speakers include
- Dennis Baldocchi, University of California, Berkeley, USA
- Lisa Emberson, Stockholm Environment Institute and University of York, U.K.
- Lisa Ainsworth, USDA/ARS and University of Illinois, USA
- Koike Takayoshi, Hokkaido University, Japan
- Harry Harmens, Centre for Ecology and Hydrology, Environment Centre Wales, U.K.

It's no big surprise that humans are impacting the planet. But a new study pinpoints a sobering connection.
As human life expectancy increases, so does the percentage of invasive and endangered birds and mammals, according to a study by the University of California, Davis.
Aldo Leopold termed “land sickness,” the study said.
Human life expectancy, which is rarely included among indexes that examine human impacts on the environment, surfaced as the key predictor of global invasions and extinctions.
“It’s not a random pattern,” said lead author Aaron Lotz, a postdoctoral scholar in the UC Davis Department of Wildlife, Fish and Conservation Biology when the study was conducted. “Out of all this data, that one factor — human life expectancy — was the determining factor for endangered and invasive birds and mammals.”
The study analyzed data from 100 countries, which included roughly 87 percent of the world’s population, 43 percent of global GDP per capita, and covered 74 percent of the Earth’s total land area. Additional factors considered were agricultural intensity, rainfall, pesticide regulation, energy efficiency, wilderness protection, latitude, export-import ratio, undernourishment, adult literacy, female participation in government and total population.
The findings include:
- New Zealand, the United States and the Philippines had among the highest percentages of endangered and invasive birds.
- New Zealand had the highest percentage of all endangered and invasive species combined, largely due to its lack of native terrestrial mammals. The study said that in the past 700 to 800 years since the country was colonized, it has experienced massive invasion by nonindigenous species, resulting in catastrophic biodiversity loss.
- African countries had the lowest percentage of invasive and endangered birds and mammals. These countries have had very little international trade, which limits opportunities for biological invasion.
- As GDP per capita — a standard measure of affluence — increased in a country, so did the percentage of invasive birds and mammals.
- As total biodiversity and total land area increased in a country, so did the percentage of endangered birds. (Biodiversity in this context is not a measure of health but refers to the number of species in an area.)
Lotz said the study’s results indicate the need for a better scientific understanding of the complex interactions among humans and their environment.
“Some studies have this view that there’s wildlife and then there’s us,” said Lotz. “But we’re part of the ecosystem. We need to start relating humans to the environment in our research and not leave them out of the equation. We need to realize we have a direct link to nature.”
