The people of the World Wildlife Fund (WWF) have found a pretty remarkable way to lure people into buying trees and plant them in Indonesia. In fact, all the users have to do is to donate money and wait for the tree to be planted in the Sebangau National Forest in Central Kalimantan, Indonesia. What's interesting is that after buying the tree you also get a KML file that lets you import a new location in Google Earth. The coordinates actually get you to the location of your tree, allowing you to track the evolution of the tree.

What's interesting is that the Mountain View company will constantly update the mapping tool so you should check the tree location every once a while, as there might be new satellite imagery waiting for you. Every tree costs $5.50 and can be bought from this website, the donation being made through the PayPal payment system.

"Your baby tree will start out as a seed. But since babies need special care and protection, the seed will initially be planted in a nursery where it will be nurtured with the help of the local indigenous Dayak community. Your $5.50 will pay for the seed, land, nursery, maintenance, protection and final transplantation. After your baby tree is planted, we will send you an email so you could check it out on Google Earth," it is mentioned on the official website of the campaign.

The website has also published a KML file compatible with Google Earth, so all the interested users have the possibility to check the list of the already-purchased trees straight from the Google mapping solution. In case you want to download the latest version of Google Earth, you can take it for free straight from Softpedia.
