The Earth may be known as the Blue Marble, but one of it's most important colors is green. Green is the sign of life on our humble home planet, so in honor of St. Patrick's Day and its signature color, we're taking a look at some of the greenest places on the planet:

Possibly the greenest areas on Earth are its rain forests, including the Congo, picture above.

The Congo River Basin's rainforests are the second largest in the world, after the Amazon. The Congo is home to a wealth of biodiversity over 10,000 plant species, 1,000 bird species and 400 mammal species, including three great ape species.

The size of the Congo rainforests means that they can absorb large amounts of carbon dioxide from the atmosphere and produce oxygen that goes back into it. This gas production and consumption has earned the forests the nickname of 'second lungs of the Earth' (the Amazon is the first).
