 La Biodiversidad 
Reino Fungi
Reino Animalia
Reino Plantae
In its more restricted circumscription, the kingdom Plantae refers to the group of terrestrial plants, which are the photosynthetic multicellular eukaryotic organisms, descendants of the first green algae that managed to colonize the earth's surface and are what we more commonly call plant or vegetable.
In the scientific classification of living beings, animals or metazoans constitute a kingdom that brings together a wide group of organisms that are eukaryotes, heterotrophs, multicellular and tissue. Animals form a natural group closely related to fungi. The part of biology that studies animals is zoology.
In biology, the term Fungi is used to designate a taxon or group of eukaryotic organisms, including molds, yeasts, and mushroom-producing organisms. They are distinguished from plants in that they are heterotrophic; and of animals in which they have cell walls, such as plants, made up of chitin, instead of cellulose.
	
Summary
Mexico is in a very interesting geographical position. Secondly, Mexico has a fascinating mountain region that crosses the territory from east to west, with an extension of almost 900 km, around latitudes of 19 to 20° N. The so-called Transversal Neovolcanic Axis is formed by volcanoes. The fact that these two large biogeographic zones converge in Mexico is one of the factors that explains their high diversity of species and ecosys tems.
To the east of the Mixteco Knot is the Sierra Madre de Oaxaca , which borders on its eastern part with the lower area of the Isthmus of Tehuantepec. Further south are the Sierra Madre de Chiapas and the Serconías de Soconusco, which frame the Central Table of Chiapas, an elevated area of cold weather located in the middle of a tropical zone. The Sierra Madre de Chiapas has its peak at the Tacaná volcano , right on the border between Chi apas and Guatemala.
In the mountainous areas, at intermediate altitudes, we have a very interesting ecosys tem called mountain mesophyll forest , which has the characteristic that species of tropical and temperate climates coexist there. Also at intermediate altitudes, especially on the great plateau of the Mexican Highlands, one can find an incredible variety of desert and semi-desert ecosystems . In higher altitudes we have temperate forests of oaks, pines, mixed forests and oyameles forests, among others.
Mexico not only has a high diversity of ecosystems, but it is also surprising that, in many places, the landscape changes dramatically over very short distances. This is surprising, if we think that the conti nental territory of Mexico represents only 1.3% of the total land emerged on the planet . For this reason, Mexico is considered a megadiverse country. Mega-diverse countries are those in which a greater percentage of known species is distributed than would be expected according to the percentage of land that corresponds to them .
There are only 17 mega-diverse countries in the world and Mexico is one of them. In fact, for some taxonomic groups, such as mammals and reptiles, Mexico is the country that has the highest diversity of species.
Written
As we saw in Section, throughout history the human being has had a strong im pact on nature. For a long time it has been considered that the negative effect that the human being has on the environment is, to a certain extent, inevitable in order to obtain in return the natural resources that they need to subsist and to enjoy the benefits of de velopment and progress. However, the level of environmental deterioration that occurs globally leads us to pause to reflect on this logic. The impact of human beings on nature also depends on their customs in regard to the pro duction and consumption of food, as well as the use of energy, water and other raw materials.
Societies with different consumption patterns produce different types and intensities of environmental deterioration. Another factor that determines the level of impact that human beings have on the environment are the technologies they use.
Pollution
From its interaction with nature, human being has always produced a certain level of pollution, but since the Industrial Revolution, in the eighteenth century, this phenomenon has been accentuated At this time, at least in Europe, they began to develop a series of technologies that had the effect of accelerating the production and distribution of food and many other consumer goods, leading to an activation of national economies. Pollution can be defined as the presence and accumulation of external components that may be of physical, chemical or biological origin, which affect the health of natural ecosystems by being harmful for the living beings that inhabit them, by altering fundamental ecosystem processes. Pollution is one of the ways in which environmental deterioration manifests itself, sometimes at local scales and sometimes at wider geographical scales. Toxic substances and environmental conditions are called pollutants that, upon reaching high levels, alter the original conditions of ecosystems and damage organisms, decreasing their performance and sometimes causing their death.
Global Warming
The Earth's atmosphere is a system that has very interesting properties, which ha given it enough stability so that life has flourished there. The chemical com position of the atmosphere is such that it functions as a kind of shelter that protects it from extreme temperatures. " On the Moon, for exam tures can reach 123 r example, without atmosphere, tempera °C when sunlight hits its surface, while where there is no sun, the temperature reaches -153 "C. This does not happen on Earth, because the atmosphere produces a phenomenon known as the greenhouse effect, which dampens temperature reflected in the changes A fraction of the solar radiation that Earth receives into space, and another fraction passes through the atmosphere and heats the Earth's surface, which, as a result, emits infrared radiation.
Climate Change
By changing the temperature of the atmosphere , naturally the other elements of the climate will also be altered, since these are environmental factors that vary in coordination. Thus, as the Earth's atmosphere warmed, the patterns of precipitation, atmospheric pressure and winds in different parts of the world have also begun to change. As we saw in Stage 3 , there is a whole system of classification of ch mates, depending mainly on the behavior of temperature and rainfall throughout the year , and of course, associated with each type of climate, there is a particular type of vegetation, as we can see in Figure 4 12d. Although each type of climate is characterized by this average behavior of the elements of the cli mate, it is also true that, in a particular year, temperatures and rainfall may be more or less remote from the average.
Even extreme events can occur, for example, years with a very acute drought, with particularly high temperatures during spring or with a very high frequency of hurri canes. That is why it has been difficult for climatologists to conclude unequivocally that we are witnessing global climate change, because if the behavior of precipitation and temperature moves away from the average in a par ticular year, in three or Even in 10 or 20 years, this does not necessarily represent a long-term directional trend.
Ecological Footprint
The ecological footprint is commonly evaluated in terms of the area of ecologically pro ductive land or water , as well as the volume of air, necessary to generate resources and also to assimilate the waste produced by beings humans according to their way of life. The mark that the human being has left and is leaving on our planet is very deep. An attempt has been made to project the conditions under which global warming could be limited so thatit does not exceed 1.5 °C. Global net emissions of CO, of human origin would have to be reduced by 45% by 2030 and continue to decrease until they reach zero by approximately 2050.
It is essential not to underestimate the important effect that such personal decisions can have on the environment. As already stated, it is evident that human beings have already left an indelible hue on our planet from the demand for natural resources that we have exerted on it. Natural ecosystems have the capacity to regenerate, and for this reason it is said that biotic resources are renewable . However, if we demand from them larger quantities than the ecosystems themselves are capable of regenerating, then we will be causing a deep and perhaps irreversible deterioration of nature.
Based on these ideas, the concept of the «ecological footprint» has been which has been proposed as a way of developed since the early 1990s measuring the level of ings exert on nature. These types of questions help us increase our level of ecological awareness, our effect on the plans by trying to quantify our planet, either as individuals or as societies, and, therefore, begin to take responsibility for our de cisions and our way of Interact with nature.
