The Amazon Rainforest encompasses 2,700,000 square miles. It represents over half of the planet's remaining rainforests and comprises the largest and most bio-diverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species. Know as the “Lungs of the Earth”, experts estimate that we are losing 137 plant, animal and insect species every single day due to rainforest deforestation. That equates to 50,000 species a year.
