Perhaps you're thinking far bigger than umbrellas. Perhaps you'd rather invest in the sort of canopy that shelters the entire future of humanity - the Rainforest.
The World Land Trust allows you to purchase an acre of Rainforest. By giving a Gift Acre of rainforest, you're allowing one acre to be bought, protected and managed through The World Land Trust.
