Amazon Rainforest in the context of "Squirrel monkey"

Brazil once had the highest deforestation rate in the world, and recent data still shows high rates of deforestation. Between 2001 and 2023, Brazil lost 68.9 Mha of tree cover (13% of its total tree cover lost since 2000), and in 2022, Brazilian forest loss accounted for 43% of global deforestation. In 2005, Brazil still had the largest area of forest removed annually. Since 1970, over 700,000 square kilometres (270,000 sq mi) of the Amazon rainforest have been destroyed. In 2001, the Amazon was approximately 5,400,000 square kilometres (2,100,000 sq mi), which is only 87% of the Amazon's original size. According to official data, about 729,000 km² have already been deforested in the Amazon biome, which corresponds to 17% of the total. 300,000 km² have been deforested in the last 20 years.

Rainforests have decreased in size primarily due to deforestation. Between May 2000 and August 2006, Brazil lost nearly 150,000 square kilometres (58,000 sq mi) of forest, an area larger than Greece. According to the Living Planet Report 2010, deforestation continues at an alarming rate. At the Convention on Biological Diversity's 9th Conference, 67 ministers signed up to help achieve zero net deforestation by 2020. Due to deforestation the Amazon was a net emitter of greenhouse gas in the 2010s.

The following is a list of the 100 largest cities in the Americas by city proper population using the most recent official estimate.

Nauta is a town in the northeastern part of Loreto Province in the Peruvian Amazon, roughly 62 miles (100 km) south of Iquitos, the provincial capital. Nauta is located on the north bank of the Marañón River, a major tributary of the Upper Amazon, a few miles from the confluence of the Río Ucayali.

Established by Manuel Pacaya–Samiria, a leader of the Kokama people, following the 1830 uprising at the Jesuit mission of Lagunas, Nauta soon became the primary commercial hub of the Peruvian selva baja (known also as Omagua, or the Amazonian lowlands). In 1853, a Brazilian-owned paddle steamer made it all the way to Nauta.

Richard Evans Schultes (SHULL-tees; January 12, 1915 – April 10, 2001) was an American biologist, considered to be the father of modern ethnobotany. He is known for his studies of the uses of plants by indigenous peoples, especially the indigenous peoples of the Americas. He worked on entheogenic or hallucinogenic plants, particularly in Mexico and the Amazon, involving lifelong collaborations with chemists. He had charismatic influence as an educator at Harvard University; several of his students and colleagues went on to write popular books and assume influential positions in museums, botanical gardens, and popular culture.

His book The Plants of the Gods: Their Sacred, Healing, and Hallucinogenic Powers (1979), co-authored with chemist Albert Hofmann, the discoverer of LSD, is considered his greatest popular work: it has never been out of print and was revised into an expanded second edition, based on a German translation by Christian Rätsch (1998), in 2001.
