Biodiversity suffers from the demands of the dominant species, which is now destroying natural habitats on a scale equal to its population and its technological capacity. For urban and agricultural purposes, or simply for exploiting the wealth of the region, all kinds of ecosystems are being stripped. The forest habitats are the most notable example. Every day, and all around the world, approximately 1 and 1/2 million trees are felled. Barely half of them are replaced. And when they are, the 100-year-old trees are substituted by very young ones, which are not capable of carrying out the same functions. The forest is the most varied, complex, and qualified scope of land for providing basic elements. It is the most nourishing and where the most living species nourish. Without a doubt, it is the home to the largest number of species. More than half of all species on the planet live in the forest. And at least 70% of the vital multiplicity of the planet is aided by it. But above all, and at this time, the forest is considered, more than ever, to be the great solution. One of the great disasters of our world is the loss of soil. The forest creates soil and maintains it. And the forest, right now, could also be the best therapy for climate change because they even act like a fixer, not only for CO2, which we already know, but the forests fix noise pollution. They fix water pollution, and they fix soil pollution. Trees have also invented isolating control and reduction systems for the strongest contaminants, including the most aggressive heavy metals like mercury, lead, and cadmium. Right now, there isn’t anything wiser than having the maximum number of trees in the world because what they are doing is creating good living conditions. They are creating raw materials, and they are curing the worst environmental diseases.
