What is slash and burns?

Slash and Burn is a forestry technique that includes a decrease in trees and shrubs on a large line of Earth, allowing them to dry and then ignite. It is a fast and effective method for cleaning a piece of land, usually with the intention of converting it into agricultural use. This soil clearing method is also cited as the main cause of deforestation around the world, because it is very destructive when it is not practiced sustainably. People have used fire to clean soil for thousands of years, although early methods have been practiced on a much smaller scale. Many European forests bear evidence of earlier slashes and burns, and it is not unusual in Africa and Australia. Theevyi soil experiences a short explosion of fertility, thanks to the large amount of biomass that has been burned and is managed for several seasons before it can return to the forest. If the technique is practiced in a very slow rotation, with several decades between each Burning episode can be in fact healthy for the forest, allowing new growthHe established and supplemented the soil.

, however, usually jumping and combustion of agriculture completely promotes the country and contributes to the erosion and final collapse of the environment in the area that was treated. Instead of recovering for several years, the soil can take many decades to return to the earlier level of fertility, and in the meantime, species that settled in the meantime can assert themselves, thus suffocating slow growing native trees and plants. It also reduces the animals of the habitat and can contribute to poor air quality when it is a large scale practiced as it is in Amazon.

Economically useful trees and plants will usually be removed before the burns. The remaining brush and unhealthy trees are freely collected to form large fires that can burn weeks before the exhaustion of dried fuel. A large scale of slashes and burnis actually visible from space and many environmental activistsIt shows photographs of technology that is practiced in the Amazon when trying to convince people that this practice is dangerous and unsustainable.

people who are against this form of agriculture have been working on promoting alternatives to this practice, from the encouragement of people to grow crops under the rainforest cover to the promotion of vegetarian diet so that the soil in South America does not have to be cleaned for cattle for cattle. It is also growing on the internal economic value of forests as a source of new medicine, tourist income and living space for animals and humans.
