Try a few simple ways to take care of nature with your children

Children love outdoor activities — nature hikes, planting seeds, sifting sand — and adults love quality time, which makes Earth Day the perfect opportunity for family togetherness and fun.

Below are 10 simple green things you and the keiki can do on any day, plus some Earth Month events to enjoy.

1. Plant a tree

The Polynesian Voyaging Society invites everyone to plant a tree in the name of the Hokule‘a’s Malama Honua worldwide voyage, aiming for at least a million, “a number we might need to offset any carbon our voyage might create,” said PVS learning center director Miki Tomita.

>> Need a tree to plant? Get one for free at the 1,000 Tree Giveaway by Malama Manoa and the Outdoor Circle, 8 a.m.-noon Sunday in the Manoa Valley District Park Pavilion. Call 222-5235.
