Expository Text on the Environment

Expository Text on the Environment

The environment is, simply put, the environment in which life sustains, grows, reproduces. All forms of life, however small or complex they may be, exist in a continuous relationship with their surroundings: they feed on available resources, defends itself from threats and eventually joins the environment, upon death, providing matter and energy to others living beings who in turn take advantage of it. Life, therefore, consists of a complex series of physical, chemical, and biotic exchanges between organisms and its environment, that is, its environment.

Seen this way, the environment is much more than the place we inhabit. The environment is of key importance for the well-being and continuity of life, and that is why throughout the history of the planet Drastic changes in the environment have repercussions, often dire, on life in general.

For example, all the mass extinctions that took place in prehistory have their explanation in environmental changes, which occurred so rapidly or violently that most of the

species The living creatures could not adapt in time, and they disappeared. This is what happened, for example, with the fall of the meteorite that extinguished the dinosaurs and 75% of life on the planet 65 million years ago.

Environmental damage

The environment is not, as we have seen, something static and permanent but can change as a result of the appearance of substances new, or of the same substances as always but in different proportions. For example, the eruption of a volcano it not only spews lava towards its surroundings, forming new layers of rock as it solidifies, but it also spews into the atmosphere gases and tons of volcanic ash, whose composition and properties are different from those of the region before the volcano exploded. And this sudden appearance of gases and substances has a detrimental effect on the ecosystems close, as it damages the life around them irreparably.

But volcanic eruptions are very sporadic and last a limited time, so given the long enough, life regains lost ground and things go back to being more or less as were. Or even if they don't do it again, new life forms, adapted to the new environment, will emerge and thrive if given enough time.

In contrast, the damage caused to the environment by humanity has much more damaging effects in the long term, although in the short term it may appear less harmful than the eruption of a volcano. Dumping polluting gases in the atmosphere, dirty water in the seas o plastics and garbage around the world are terrible and constant factors for the environment.

And although humanity depends, as much as the others animals, that their environment remains more or less stable, the Homo sapiens we are the only species that in a short period of existence (barely 400,000 years or so) has altered the environment in a drastic and often unpredictable way. We have not only created new environments and discovered materials that did not exist before but we have also caused the extinction of entire species and, as they warn some sectors of society, we could be turning the planet into an inhospitable place for us themselves.

Defense of the environment

The environmental defense groups, also known as environmentalists or environmentalistsThey have been around in the West since the mid-20th century, more or less. These political, social and economic movements fight for a more harmonious coexistence between human beings and the environment, and warn of the dangers of not taking active responsibility for the environmental damage caused by our way of working. life.

In the final decades of the 20th century and the beginning of the 21st century, these voices have multiplied and have echoed the serious warnings of the science regarding the immediate future of humanity, if pertinent measures are not taken to reduce the damage we do to the environment. Warnings that, on the other hand, some question, claiming that it is an interpretation only of natural cycles in which the human being has little to do.

There is, however, incontrovertible evidence regarding the environmental damage caused by human industries. Climate change, microplastic pollution and loss of biodiversity These are three examples of this that could cost future generations dearly, but whose solution is difficult as it contradicts current economic models. That is why, according to environmental voices, we are obliged to undertake a change in the production model on the entire planet, before the consequences are terrible and irreversible.

What is an expository text?

A expositive text It is a type of writing whose essential mission is to provide the reader, in an objective way, specific and specific information on a specific topic. In this it differs from other textual types, such as argumentative text or the narrative text, since the expository text does not contain or arguments or opinions in favor of a perspective, nor any kind of story or narration.

Expository texts focus above all on information, so they are usually impersonal and rigorous in their approach to the subject. They are texts in which data, observations, quotes and other resources to, as the name implies, expose the reader to an aspect of reality.

To write an expository text we must first of all document ourselves on the desired topic and then reproduce the ideas, of the most general to the most specific (or the other way around), without involving our own points of view on the matter, but adhering to the strictly informative.
