The extensive use of the poison DDT in agriculture was a death sentence to the California Brown Pelican. Rachel Carson's book Silent Spring raised people's awareness of the issue and helped kick off the environmental movement.

The first Earth Day I celebrated was Earth Day 1 at UC Davis in California. At the time I was Director of Peace Corps Public Affairs for Northern California and was recruiting at Davis. Earth Day 1 made a deep impact on how I viewed the world. I quit my job and became Executive Director of the Sacramento Ecology Center. Ever since, on one level of another, I have been an environmentalist.

To celebrate Earth Day 2012, I am using my blog to feature two wonderful animals that were on the edge of extinction before they were saved by growing environmental awareness. The California Brown Pelican was victim of the extensive use of the poison DDT. Elephant Seals were hunted to the brink of extinction for their blubber, which was turned into lamp oil.

The world would be a much poorer place with out these animals.

Have you heard the news? It's Earth Day.

The world would be a poorer place if we could no longer hear the roar of a bull Elephant Seal.

Or watch one scratch his nose.

I call this photo of Brown Pelicans The Committee.

Without environmental awareness and action, this magnificent bird would have never flown. Happy Earth Day 2012, and thank you.
