      The Amazon River, which begins in the Andes Mountains in Peru, is the source of twenty percent of all water that enters the oceans worldwide. At 6,400 kilometres in length, it is the second longest river in the world. During the rainy season, parts of the river are 190 kilometres wide. The Amazon River passes through the world's largest tropical rainforest. The Amazon rainforest is home to the highest number of plant and animal species on Earth. many of which are found nowhere else. There are 2.5 million kinds of insects, at least 3,000 kinds of fish, and one-fifth of all bird species in the world. The Amazon rainforest is considered one of the world's most important natural resources, as it plays a crucial role in controlling the Earth's climate and weather patterns. Unfortunately, the Amazon rainforest is under threat from human activities. The clearing of land for agriculture, logging, and the construction of roads and infrastructure has led to the destruction of 20 percent of the Amazon rainforest over the last 40 years, and an additional 20 percent is at risk of being destroyed. As deforestation continues and the effects of climate change increase, we run the risk of losing this spectacular ecosystem for future generations.
