  The researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago -- much earlier than previous estimates of around 480 million years ago, which were based on the earliest fossils of those organisms.

• Deforestation

• Forests
  Forests are critical to the survival of every living thing on Earth. Forests clean the air, regulate weather, absorb greenhouse gas emissions, and stabilize the climate--both global and local. Not to mention, forests provide habitat for 80 percent of the world's terrestrial biodiversity and livelihoods for 1.6 billion people.

• Forests and Climate Change
  Deforestation accounts for nearly 20% of all greenhouse gas emissions -- more than the world's entire transport sector. At the same time, the removal capacity of forests is decreased as forests are lost.
