The soil, origin, nature and degradation The soil is the surface of the earth’s crust that covers a large part of the continents and islands of the world. It has been formed thanks to the action of abiotic and biotic components for hundreds of millions of years by the mechanical dissolution of rocks, the incorporation [...]
Environmental pollution, pollutants and endangered species Environmental pollution, in the classical concept, occurs when certain elements that cause harmful effects accumulate in quantities that nature cannot recycle. A contaminant is a substance that is found in a medium to which it does not belong or that does so at levels that can cause adverse effects. [...]
“Borneo, a place where birds no longer sing and orangutans are homeless.” Alex Shoumatoff “Man has made the Earth hell for animals.” Arthur Schopenhauer Those of us who belong to the species Homo sapiens owe our name and surname to our two main characteristics: we are human, and we are endowed with the [...]

There are millions of people who already use electricity generated by solar energy. The world is aware of the importance of the transition towards a [...]
On this planet, the only one with life that we know, the wide biodiversity that inhabits it is born, lives, grows, eats, sleeps, reproduces, attacks, escapes and dies using energy in all these stages. We live in a wonderful planet in which biochemical energy differentiates us from all other stars. We humans, in addition to [...]
Two and a half million years ago the Homo habilis, sitting on the wooden log of a tree fallen in the Olduvai gorge, Tanzania, Africa, did not take his eyes off something that with his clumsy hands he was handling. They were a pair of pebbles and with them, based on trial and error, managed [...]
Today Earth Day is celebrated, as it has been done every April 22, since 1970. This year the theme that has been chosen is that of contamination with plastics due to concern about the subject. Plastic pollution is the accumulation of products of this material in the environment, which negatively affects the lives of almost [...]
By using clean energy instead of fossil fuel, the electric car is the most effective tool to meet the main objective of the Paris Agreement, such as limiting the increase in global warming to 2°C from its pre-industrial level. For this, the transcendental document indicates that greenhouse gas (GHG) emissions must be reduced until they [...]
The main objective of the Paris Agreement is to limit the increase in global temperature to no more than 2°C, from its pre-industrial level, by the end of this century. To achieve this key objective, greenhouse gas emissions must be reduced until they are completely eradicated. Through the premise “Zero fossil fuels” is intended to replace oil, [...]
At all times and in all sciences, there have always been visionaries, those people who anticipate situations long before other persons can glimpse them. This is the case of Jean-Baptiste Joseph Fourier (1768-1830), a French mathematician and physicist, who in 1824 calculated that an object the size of the Earth and with a similar distance [...]
