The document discusses tropical rainforests and the issues of deforestation. It notes that rainforests cover less than 6% of the Earth's land but are home to more than half of all plant and animal species. Deforestation removes nutrients from the ecosystem, degrades the soil quality over time, and can be done through burning, grazing, building, or slash-and-burn techniques. By 2050, experts predict there may no longer be any rainforests remaining if deforestation continues at its current rate.
