The Amazon rainforest is the largest tropical rainforest in the world  

The Amazon rainforest is the largest and most species-rich tract of tropical rainforest in the world.
The Amazon rainforest also known as Amazonia, or the Amazon jungle, is a moist broadleaf forest that covers most of the Amazon Basin of South America. This basin encompasses seven million square kilometers (1.7 billion acres), of which five and a half million square kilometers (1.4 billion acres) are covered by the rainforest. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, and with minor amounts in Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana. States or departments in four nations bear the name Amazonas after it.
Most travelers visit the western areas of the rain forest that remain largely untouched, such as the Loreto region of Peru, so they may not notice that the ecosystem is under siege. At current rates, 55 percent of its rain forests could be gone by 2030—a looming disaster not only for the region’s plants and animals, but for the world. "I've seen areas along the river where it's been beautiful, pristine forest one year, and the next it's been clearcut," says Harris. "That's pretty hard to take.". The Amazon River is the largest river in the world by volume, with a total flow greater than the top ten rivers worldwide combined. It accounts for approximately one-fifth of the total world river flow and has the biggest drainage basin on the planet. Not a single bridge crosses the Amazon.
The immensity of the Amazon's challenge, like the scale of its landscape, requires a long-term conservation vision backed by strong scientific expertise. WWF has been at the forefront in protecting the Amazon for more than 40 years. Our approach is succeeding because we engage local communities and partner with governments to identify mutual solutions that can bridge the needs of economic development and conservation.
In the last decades, scientific research has established a clear link between the health of the Amazon and the integrity of the global environment, but still only a fraction of its biological richness has been revealed. Today, rapid deforestation threatens the Amazon.
The Amazon is ranking first in Group E, the category for forests, national parks and nature reserves.
The Amazon rainforest was short-listed in 2008 as a candidate to one of the New7Wonders of Nature by the New Seven Wonders of the World Foundation.
