Save Kaho’olawe
Yo environmentalists! Did you know you can help restore the Hawaiian island Kaho’olawe? You can sign up for a four-day tour to clean up the desolate land and plant new vegetation. Of course, you do need to be wary of unexploded ordinance (UXO) during your stay.
If interested, you can get more info here. There’s a Facebook page about the volunteer effort and some pictures on FB.
