Whether you’re a hippie throwback, an eco-yuppie or just a concerned citizen swept up in the growing sustainability movement, there’s no shortage of ways to commemorate Earth Day, April 22.

You can rally for clean energy, recycle your cans to raise money for Japan, learn nature photography or create a compost worm bin, to name just a few of the activities planned for the entire week.

"To me it’s no longer Earth Day," said Shannon Wood, president of the Windward Ahupua‘a Alliance. "It’s not even Earth Month. It’s Earth Day every day, forever."

Wood said she voted for the first time in 1970, the same year Earth Day was founded, and has been advocating for the environment ever since.

Earth Day will be a combination of work, political activism and celebration for Wood’s group, which is sponsoring a community cleanup of debris from roadways surrounding Kawainui Marsh.

Here are some ways to get involved:
