An anonymous reader shares a report: Wondering how to show that special planet some affection this Earth Day? Adopt it. NASA has sectioned off 64,000 individual pieces of Earth to be "adopted" by supporters on their website. The pieces are about 55 miles wide and assigned randomly. Similar to adopting a highway or naming a star, participants do not get legal or property rights to their section. So whether you get the 55-mile section that contains the Taj Mahal or the one that is square in the middle of the Pacific Ocean, you benefit the same.
