However, the consequences of deforestation are far-reaching. The South American rainforest, for example, has an impact on regional and even global water cycles, and it is critical to the supply of water in Brazilian towns and neighboring nations. The Amazon actually assists some of the soy growers and beef ranchers who are removing the forest by providing water. But it also removes carbon that would otherwise be stored in the tree trunks and preserved in the soil.
The destruction of the rainforest affects many other organisms living in or near it as well. Insects such as bees, which are important for pollination, are being killed off by pesticides used on agricultural crops. Animals that rely on the forest for shelter or food include monkeys, birds, and reptiles. Human beings may use the timber or hunt certain animals for profit; however, this benefit is rarely realized because most wood from tropical forests is exported, used as fuel, or left to decay untreated.
In conclusion, the loss of the Amazonian rainforest will have significant effects on the environment and human life in general. This beautiful area of Earth plays a crucial role in maintaining a healthy climate and resource pool for future generations.
Soy cultivation in Brazil contributes to destruction of the Amazon rainforest both directly through forest clearance for new soy fields (which are often massive in size) and indirectly by displacing small farmers, who subsequently relocate to forest regions for subsistence agriculture.
Large-scale deforestation occurs when farmers clear land for crops like soy or sugarcane. The Amazon is one of the most biodiverse places on Earth, so losing its forests is bad for biodiversity. But even if a farmer only clears a few acres for soy they can have an impact on the environment. The process of clearing land for agriculture tends to damage soil quality and drain water tables, which can lead to soil erosion and flooding. In the case of soy production, this means that less carbon is stored in the soil and more of it ends up in the atmosphere as CO2.
In addition to causing land degradation, large-scale deforestation has many other negative effects for the environment. It can lead to desertification - where land is transformed from forest or grassland into arid scrub - due to the removal of vegetation that acts as a natural protector against wind and water erosion. This can be a problem for soy growers because their main source of income is dependent on having fertile soil with high rates of crop growth. Without trees to protect them from wind and water, farmers will need to invest time and energy into maintaining their soil rather than focusing on growing crops.
The primary source of deforestation in the Amazon rainforest is cattle grazing. This has been the situation in Brazil since at least the 1970s, with government data putting large-scale cattle ranching to blame for 38% of deforestation between 1966 and 1975. In Brazil, the figure is rapidly approaching 70%.
The main reason for this is the need for pasture land. In order to produce beef in quantities suitable for global markets, large areas of forest are needed. In fact, according to one estimate, the Brazilian cattle industry requires about 5 million acres of new land every year, mostly for pasture but also some for beef production. The majority of this land is deforested outside the Amazon basin, because it's the only place able to provide sufficient rainfall for cattle farming.
Another factor is the price of meat. In spite of its high cost, beef is one of the most profitable products to farm. To make money you need to maximize your output which includes trees cut down to make way for livestock feed and water supplies.
Finally, there's the issue of poverty. Many farmers rely on using the land as collateral when they take out loans from banks or microcredit organizations. If they can't pay back the loan then the bank will sell the land to cover its losses. All of these factors combine to show that development work in the Amazon rainforest is not driven by a desire for luxury goods nor oil palms nor soybeans but by economic necessity.
