With the cooperation of politicians and grassroots organizations, Bolivia is set to pass the Law of Mother Earth which will grant nature the same rights and protections as humans.

Bolivia Set to Pass Historic 'Law of Mother Earth' Which Will Grant Nature Equal Rights to Humans

The piece of legislation, called la Ley de Derechos de la Madre Tierra, is intended to encourage a radical shift in conservation attitudes and actions, to enforce new control measures on industry, and to reduce environmental destruction. The law redefines natural resources as blessings and confers the same rights to nature as to human beings, including: the right to life and to exist; the right to continue vital cycles and processes free from human alteration; the right to pure water and clean air; the right to balance; the right not to be polluted; and the right to not have cellular structure modified or genetically altered. In late 2005 Bolivia elected its first indigenous president, Evo Morales. Bolivia's successes or failures with implementation may well inform the policies of countries around the world.

Trees are one of Earth’s largest banks for storing the carbon that gets emitted by natural processes and human activities.

Where the Trees Are

Forests cover about 30 percent of the planet’s surface, and as much as 45 percent of the carbon stored on land is tied up in forests. But did global forests hold more or less carbon in the past? And could they store more in the future? Does it matter where those trees are growing? Scientists really don’t know. Josef Kellndorfer and Wayne Walker of the Woods Hole Research Center (WHRC) recently worked with colleagues at the U.S. Over six years, researchers assembled the national forest map from space-based radar, satellite sensors, computer models, and a massive amount of ground-based data. Forests in the U.S. were mapped down to a scale of 30 meters, or roughly 10 computer display pixels for every hectare of land (4 pixels per acre). “Forests are a key element for human activity,” says Kellndorfer.
