Adopt a plot.

The Geograph software already inspired many initiatives by forming a virtual globe with the help of satellite pictures and aerial photographs . One such initiative is http://www.healthyplanet.org/, an Internet platform supported by Google Maps/Earth, which allows its users to view protected parks and give them the opportunity to adopt a hectare or square kilometre within. .

90 percent of the donations goes towards local projects, to look after your chosen area. The rest stays with the charity and goes to their reserves. With the money the organization was already able to protect fenland in Great Britain, finance reforestations in Thailand and support parks in Colombia and Brazil.
