Earth Day history can inspire us all
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.
Interested in learning more about 4-H in your community? Visit our statewide 4-H program page.
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!
Reduce food waste to combat world hunger and slow global climate change
One-third of the world's food is spoiled or tossed rather than eaten, a fact that is tragic when nearly one billion people go hungry. The injustice of food waste is worsened by the fact that food decomposing in landfills emits greenhouse gases that contribute to climate change.
The conventional management of municipal waste in landfills places discarded food and plant matter into an anaerobic environment, initiating a chemical reaction that turns biomass into biogas – specifically methane, a greenhouse gas that's 28 times more potent than carbon dioxide.
Reducing the volume of the California waste stream and reducing the emission of greenhouse gases into the atmosphere are objectives that have spurred state lawmakers to enact regulations, such as Assembly Bill 939, which in 1985 mandated a 50 percent diversion of solid waste away from landfills. A 1989 update to the law also required municipalities to reach out to residents with training on greenwaste etiquette and waste diversion.
UC Cooperative Extension is working closely with the cities and county of Santa Clara in a far-reaching program to divert organic matter – food and green waste – from landfills by composting and using the product to enrich soil in the home garden.
In early June, UC Master Composter Don Krafft conducted a class on composting in a Palo Alto community center, one of 22 sessions to be offered in the spring and summer of 2018. A retired telecommunications professional, Krafft's interest in composting stemmed from his work as a Master Gardener for UC Cooperative Extension.
“I live in a townhouse, so I do worm composting. The No. 1 reason,” Krafft said, “is because it's fun.”
The composting workshops are just one component of the UC Cooperative Extension's composting efforts in Santa Clara County, led by UCCE staff research associate Cole Smith. The Environmental Protection Agency has a food recovery hierarchy, he said, which has source reduction at the top, followed by feeding the hungry, feeding animals, industrial uses, then composting, and finally delivery to a landfill.
“By diverting and recycling at the source, we reduce the diesel footprint for hauling,” Smith said. “We want to tighten the nutrient loop and the backyard is the closest place.”
The classic composting technique involves layering “browns” – dry leaves, sawdust, woody cuttings, straw, shredded newspaper and cardboard – with “greens” – grass clippings, food scraps, coffee grounds, egg shells, green plant cuttings and manure.
“Start and end with browns to keep the fruit flies down,” Krafft said. “It's like making lasagna.”
Certain foods should not be added to the home compost heap – including meat, whole eggs and dairy products.
The mix of greens and browns should be maintained evenly moist, but not soaked, and turned at regular intervals, the more often, the faster the materials decompose.
“Maintenance is completely adaptable. You can do a lot or a little and it gets easier with time,” Krafft assured the audience.
The compost is ready when the components are no longer recognizable and the pile is cold. Once composted, the former waste becomes a stable soil amendment with a pleasant earthy smell. It's then ready to be applied in the garden.
UCCE Santa Clara has also developed a three-acre composting demonstration site at Martial Cottle Park in San Jose, where volunteers are composting animal waste generated by the 4-H animal program in a project made possible by a grant from the Santa Clara Valley Water District.
The facility includes a variety of commercial and homemade compost containers, including one built by a volunteer that employs bicycle power to mix compost.
The issue of food waste is capturing significant attention not only in Santa Clara County and not only in the garden. Food waste reaches across multiple disciplines, including agriculture, environment, and public health, key areas of UC Agriculture and Natural Resources' efforts.
“Food waste is a symptom of our food systems and food practices going astray,” said Wendi Gosliner, a project scientist in the UC ANR Nutrition Policy Institute, co-founder of California Food Waste Prevention Week, which was held for the first time in March 2018.
“Addressing the issue requires researchers, practitioners, policy makers, communities and individuals to innovate and develop new solutions,” Gosliner said.
UC ANR programs that have a hand in food waste prevention include:
- Nutrition education programs – UC CalFresh and the Expanded Food and Nutrition Education Program – which teach families how to eat right and economize
- The UC Master Food Preserver Program, which offers training on canning, freezing, drying, fermenting and other techniques to preserve a summertime food bounty to eat later
- The 4-H Youth Development program, which trains youth in recycling and is providing animal manure for the Santa Clara compost demonstration site
- The UC Master Gardener Program, which endorses the use of homemade compost
- Nutrition Policy Institute, which conducts research that informs nutrition policy and programs for healthy children, families and communities
“UC ANR translates research to practice in helping communities manage food resources, learn to preserve food and compost – all parts of the food waste solution,” Gosliner said. “Thinking about these and other UC ANR activities under the umbrella of food waste prevention can help to better nourish people, protect the environment and conserve human, natural and financial resources.
