From July 1st- July 22nd, Smaller Earth and their African partner on the ground, GreenPops, will be assembling forces to attempt to plant 10,000 trees in an event called "Trees for Zambia." The event will include educational components such as documentary screenings and lectures from top environmentalists around the world, as well as allow participants to richly experience and interact with Zambian culture.
