Naomi Krysel Ricarte, México, 15 years old.
In my student life I gave myself the task of studying the issue of the loss of biodiversity in the world as well as in Mexico; this has become a very important issue in this century since the enormous problems caused by the loss of biodiversity.
I took on the task of investigating this topic with experts in environmental matters. I attended the ecology coordination with engineer Carlos Trevizo. The subject was studied very carefully and the following conclusión was the next: population growth and the demand for food has increased in recent years, this translates into increased demand for natural resources. As a result, thresholds that has have been exceded, should not have been touched, but it’s required to cover the basic needs of each person on the planet. After interviewing the engineer, we managed to reach the following conclusion: that the biggest problem that causes the loss of biodiversity comes from the environmental “immaturity” of society and of the authorities.
Currently, in the world there is a lot of overexploitation, which severely damages the ecosystem causing a rampant loss of resources and species; If this is not controlled, millions of species will disappear. 1 million species are on the verge of extinction. This is the frightening conclusion of the panel’s latest report international group of experts on biodiversity and ecosystem services of the UN, IPBES (the equivalent of the IPCC for climate change) which has become the worst data in history. It is estimated that about 23 to 36% of species are in danger of extinction without counting all the habitats that are being destroyed, of these there are a total of 4,748 threatened species (407 species more than in 2011). The total number of extinct species is of 35, 14 extinct in the wild, 749 critically endangered, and 1,518 endangered. In addition, the total number of vulnerable is of 24,811,042 of near threatened, 2,328 with insufficient data and 7,444 in a state of concern. 
In recent decades, Mexico has indicated that around 50% of natural ecosystems have been lost. The main transformations have been carried out in the humid and dry forests, the grasslands, the cloudy forests, and mangroves to a lesser degree in thickets and temperate forests. The most accessible ecosystems, more productive, with better soils and in less accessible or less productive places, with better soils and in flat places have been the ones that have undergone the greatest transformation; the main remnants are found in inaccessible or unproductive places. 
Pollution based on chemical substances has serious environmental impacts.
consequences for many species. 
For a long time, contamination was a problem on a small scale, without
However, this mostly has a solution, which is to trust society to help make a change and leave our descendants a habitable and healthy planet.
