Reforestation not only consists of planting trees where there are no longer or few, but a process that also seeks to improve the ecosystem as a whole. For this, an environmental study is necessary, since not all types of plantations are good for ecological balance.
Eucalyptus plantations are a widespread practice in Asia, India and Latin America. They are fast growing trees and therefore of rapid profit. Companies use the growing demand for paper and the creation of jobs as an alibi, knowing the terrible effects that these species have on the environment.
This has a negative environmental impact for the ecosystem. Soils are sterilized and acidified, underground water reserves diminish, rivers dry up and biodiversity is reduced. It causes more serious damage than it was intended to repair.
Farmers in Niger rehabilitated about 5 million hectares between 1986 and 2006. They used simple techniques that do not harm the ecosystem. In this way, the population made the desert fertile ground, and therefore a productive agriculture.
Martin Luther King said: “even if I knew that the world was going to end tomorrow, I, still today, would not stop planting a tree”, since then, humans have used trees as a double-edged sword. It has been able to make the desert a rich area, and the Amazon a poor area.
It is worth asking ourselves if the human being will position himself in favor of the planet that gave him birth and renewable energies for its care, a correct reforestation and a general respect for the environment. Or, on the contrary, it will continue with the bad practices that have caused damage to rivers, seas, forests and oceans.
