What You'll Learn
The Amazon is the world's largest tropical rainforest
The Amazon rainforest is a vast and vibrant ecosystem, receiving torrential rainfall of between 1,500 mm and 3,000 mm every year. The region has all the typical attributes of a tropical environment, with temperatures averaging 27.9°C during the dry season and 25.8°C during the rainy season. The rainforest's immense extent and great continuity are a reflection of the high rainfall, high humidity, and monotonously high temperatures that prevail in the region. The Amazon's influence on the movement of moisture extends beyond the water that flows down the Amazon River. The trees of the rainforest pump around 20 billion tonnes of water vapour into the atmosphere every day via transpiration.
The Amazon River Basin encompasses a variety of landscapes and ecosystems, including rainforests, seasonal forests, deciduous forests, flooded forests, and savannas. The basin is drained by the Amazon River, which has more than 1,100 tributaries and streams. The Amazon is home to the largest number of freshwater fish species in the world. The vast forest consists of four layers, each featuring its own ecosystem and specially adapted plants and animals.
The Amazon has been under threat from deforestation for many years, with the Brazilian government incentivizing forest clearing for beef production and ranching. Settlers have also cleared land to obtain lumber and to create grazing pastures and farmland. In recent years, the Amazon River Basin has also been under siege from fire and other destructive human interventions. These threats have put the Amazon at risk of reaching a tipping point, where it could no longer sustain itself as a tropical rainforest. This would have devastating consequences for our fight against climate change.

It covers an area of 2.3 million square miles
The Amazon rainforest is the world's largest tropical rainforest. It covers an area of 2.3 million square miles (6 million square kilometres). This makes it roughly the same size as the continent of Australia. To be precise, the Amazon is slightly smaller than Australia, which is the world's sixth-largest country by total area.
The Amazon rainforest is located in northern South America and comprises about 40% of Brazil's total area. It is bounded by the Guiana Highlands to the north, the Andes Mountains to the west, the Brazilian central plateau to the south, and the Atlantic Ocean to the east. The forest widens from a 200-mile (320 km) front along the Atlantic to a belt 1,200 miles (1,900 km) wide at the Andean foothills.
The Amazon is home to the richest and most varied biological reservoir in the world, containing several million species of insects, plants, birds, and other forms of life, many of which are still unrecorded by science. The rainforest is also home to more than 30 million people, including approximately 2.7 million indigenous people from over 350 different ethnic groups.
The Amazon River Basin, of which the rainforest is a part, covers some 40% of the South American continent and includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, and Suriname, as well as French Guiana, a department of France. The Amazon River, which gives life to the rainforest, is the second-longest river in the world after the Nile and accounts for 15-16% of the world's total river discharge into the oceans.

The Amazon is home to 10% of the world's biodiversity
The Amazon is the world's largest tropical rainforest, covering an area of 2.3 million square miles (6 million square kilometres). It is comparable in size to the continent of Australia. The rainforest stretches from the Atlantic Ocean in the east to the tree line of the Andes in the west. The forest widens from a 200-mile (320-km) front along the Atlantic to a belt 1,200 miles (1,900 km) wide at the Andean foothills. Brazil holds approximately 60 percent of the Amazon within its borders.
The Amazon is also home to a diverse range of wildlife, including anacondas, sloths, macaws, capybaras, tapirs, squirrel monkeys, red howler monkeys, jaguars, caimans, tarantulas, leaf-cutter ants, scarlet ibis, and black skimmers. Many of these species are unique to the Amazon, and scientists estimate that there are places in the Amazon where up to 90% of the species are yet to be discovered. The Amazon is also home to numerous indigenous communities, who have a right to their livelihoods and territories.
The Amazon is currently facing several threats, including deforestation, fires, and degradation. Data from the first half of 2022 shows that forest loss is continuing to grow, with 17% of Amazon forests already lost and an additional 17% degraded. Deforestation is driven by logging, agriculture, and grazing, with large-scale industrial timber plantations replacing natural forest areas, resulting in a loss of biodiversity. The rollback of environmental protections and enforcement under the Bolsonaro government has also harmed indigenous communities and accelerated deforestation and habitat destruction.
The World Bank-led Amazon Sustainable Landscapes (ASL) Program aims to address these challenges by improving the management of 82 million hectares of forest across Brazil, Colombia, and Peru. The ASL will work to protect indigenous peoples and their rights, enforce existing protections, and connect protected areas to make biodiversity more secure.

Australia is the world's sixth-largest country by total area
Australia is officially the Commonwealth of Australia, a country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It has a total area of 7,688,287 square kilometres (2,968,464 square miles), making it the sixth-largest country in the world.
The Amazon rainforest, on the other hand, covers an area of 2,300,000 square miles (6,000,000 square kilometres). Some sources state that the Amazon is the size of the continent of Australia, covering an area of 2.8 million square miles. However, this is not accurate, as the Amazon rainforest is significantly smaller than Australia.
Australia is the largest country in Oceania and is sometimes considered the world's largest island, often dubbed the "island continent". It has a long coastline of 35,877 kilometres (22,293 miles), excluding all offshore islands. Australia also has an exclusive economic zone of 8,148,250 square kilometres (3,146,060 square miles), which does not include the Australian Antarctic Territory.
The Australian mainland is relatively flat, with an average height of 325 metres (1,066 feet) compared to 870 metres (2,850 feet) for all continents. The country has a wide variety of landscapes and climates, including deserts in the interior and tropical rainforests along the coast. Australia is highly urbanised, with 67% of the population living in metropolitan areas in 2018. The population is heavily concentrated on the east coast, particularly in the south-eastern region between South East Queensland and Adelaide.

The Amazon's influence on the movement of moisture extends beyond the Amazon River Basin
The Amazon rainforest is the world's largest tropical rainforest, covering an area of nearly 2.8 million square miles. This makes it roughly the same size as the continent of Australia. The Amazon rainforest covers 40% of the South American continent and includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, and Suriname, as well as French Guiana, a department of France. Brazil holds approximately 60% of the Amazon within its borders.
The Amazon River Basin receives about 2000 mm of precipitation annually, contributing about 17% of the global river freshwater input to the oceans. The hydroclimatic variations in the Amazon River Basin have profound impacts on the marine ecosystem in the Amazon plume region, leading to enhanced seasonalities in river discharge and ocean salinity.
The Amazon rainforest is incredibly biodiverse, housing at least 10% of the world's known species, including 370 types of reptiles and over 3,000 freshwater fish species. The rainforest's ability to create a moist sub-canopy microclimate is essential for containing and recycling moisture. However, deforestation and fires compromise this ability, making the environment drier and more susceptible to fires. Deforestation also reduces the Amazon's capacity to absorb carbon dioxide, limiting its function as a carbon sink and contributing to climate change.
The Amazon's influence on moisture movement has far-reaching consequences, affecting agricultural output in countries thousands of miles away. By sustaining delicate water cycles, the Amazon supports ecosystems and human activities on a global scale, underscoring the importance of its preservation for regional stability and global climate health.
