There’s no I in Earth Day.

So learn how to take one for Team All Living Things from TreePeople. The nonprofit teaches simple ways to improve the planet all year ’round.

They make it easy to get involved.

If your thumb has never been green and you like it that way, you can gift tree dedications for about $25 a pop from the comfort of your desk chair.

But if you want to roll up your sleeves, sign up for community and school plantings and care missions. This weekend, train to be a planting supervisor, monitor Angeles National Forest, green Newcomb Academy in Long Beach with Long Beach Organics, or give Tulita Elementary School in Redondo Beach some special treatment.

Already booked? They always need volunteers at their headquarters — a state-of-the-art yurt village in Coldwater Canyon Park.

Because there is a you in helping out.
