There is no shortage of ways to be a tree hugger today.
To celebrate Earth Day, the Environmental Protection Agency has offered a list of things around the country - and in the Bay Area - to do on Monday, which range from a big San Francisco Earth Day Festival, complete with "sustainability discussions" and music, to the 7th annual Lafayette Earth Day Celebration, complete with an organic lunch and live music.
There are also upcoming events this weekend in Santa Clara County, including Spring in Guadalupe Gardens on Saturday in San Jose and the California Native Plant Society's 40th Annual Wildflower Show this weekend at Mission College in Santa Clara. For South Bay countywide events, click here.

Earth Day is now celebrated worldwide, in nearly 200 countries across the globe.
It was born at a UNESCO Conference in San Francisco in 1969.
