Can Google Save the Forests?

Google and a variety of space agencies are fighting global warming by measuring forests around the world from space. Google will use its Google Earth to track deforestation, which is responsible for approximately one-fifth of all greenhouse gases that come from human activities. “The only way to measure forests efficiently is from space,” said the director of the initiative. NASA, the European Space Agency, and space agencies in Japan, Germany, Italy, India, and Brazil will all contribute to mapping forests from space.
