Every modern inhabitant of the Earth knows very well that the environmental problems of the planet are a real scourge of the 21st century. Also, many think about the issue of preserving and restoring the environment. Otherwise, future generations will only get a lifeless surface.

One man in the field

It is likely that at least once in a lifetime each of us asked ourselves the question: "What environmental problems of the planet exist at the present time and what can I do to solve them?" It would seem, indeed, that only one person can? Nevertheless, each of us is capable of much. First, begin to "look after" the environment on your own. For example, throwing garbage into strictly designated containers, and it will not be superfluous to also pay attention to the separation of waste into specific materials (glass in one tank, and plastic in another). In addition, you can regulate and gradually reduce the consumption of both electricity and other resources (water, gas) necessary for your comfortable living. In that case,if you are a driver and are faced with the choice of a suitable vehicle, then you should pay attention to cars that have a reduced content of harmful compounds in exhaust gases. It will also be right - both for you and for the whole planet - a small engine size installed in the selected car model. And, as a result, reduced fuel consumption. With such simple and accessible activities for everyone, we can solve the environmental problems of the planet.

Let's help the whole world

However, despite everything described above, you will not be left alone in this struggle. As a rule, the policy of many modern states is aimed at the well-known environmental problems of the planet and, of course, ways to solve them. In addition, there is an active propaganda program, the purpose of which is to limit deforestation and the extermination of rare representatives of flora and fauna. Nevertheless, such a policy of world powers is quite purposeful and allows you to create conditions for the normal life of the population, which at the same time do not violate natural ecosystems.

Ecological problems of the planet: list

Modern scientists identify about a few dozen basic issues that require special attention. Such global environmental problems of the planet arise as a result of significant changes in the natural environment. And those, in turn, are the result of destructive natural disasters.disasters, as well as the ever-increasing human impact. The environmental problems of the planet are quite easy to list. One of the first places is air pollution. Each of us knows from an early age that, due to the content of a certain percentage of oxygen in the air space of the planet, we are able to exist normally. However, every day we not only consume oxygen, but also exhale carbon dioxide. But there are still plants and factories, cars and motorcycles roam around the world, planes fly and trains knock on the rails. All of the above objects in the process of their work emit substances of a certain composition, which only aggravates the situation and increases the environmental problems of the planet Earth. Unfortunately, even though modern factories are equipped with the latest developments in cleaning systems, the state of the airspace is gradually deteriorating.

Deforestation

Ever since the school biology course, we know that representatives of the plant world contribute to maintaining the balance of substances in the atmosphere. Thanks to natural processes, such as photosynthesis, the green spaces of the Earth not only purify the air of harmful impurities, but also gradually enrich it with oxygen. Thus, it is easy to conclude that the extermination of flora, in particular forests, only exacerbates the global environmental problems of the planet. Unfortunately, the economic activity of mankind leads to the fact that felling is carried out on an especially large scale, butGreen spaces are often not replenished.

Decrease in fertile land

Similar environmental problems of the planet arise as a result of the previously mentioned deforestation. In addition, the misuse of various agricultural techniques and improper farming also leads to the depletion of the fertile layer. And pesticides and other chemical fertilizers for many years poison not only the soil, but also all living organisms that are interconnected with it. But, as you know, the layers of fertile land are restored much more slowly than forests. It will take more than one century to fully replace the lost land cover.

Decreasing fresh water supplies

If you are asked: "What environmental problems of the planet are known?", you have the right to immediately remember the life-giving moisture. Indeed, in some regions there is already an acute shortage of this resource. And as time goes on, this situation will only get worse. Therefore, the above topic can be considered one of the most important in the list of "Ecological problems of the planet". Examples of misuse of water can be found everywhere. Starting from the pollution of lakes and rivers by all kinds of industrial enterprises and ending with the irrational consumption of resources at the household level. In this regard, already at the present time, many natural reservoirs are closed areas for swimming. However, it doesn't end there.environmental problems of the planet. The list can be continued with the next item.

Destruction of flora and fauna

Scientists have calculated that in the modern world one representative of the animal or plant world of the planet dies every hour. At the same time, it is important to remember that not only poachers are involved in such actions, but also ordinary people who consider themselves respectable citizens of their country. Every day, mankind conquers more and more new territories both for the construction of their own housing and for agricultural and industrial needs. And animals have to move to new lands or die, remaining to live in an ecosystem destroyed by anthropogenic factors. Among other things, it must be remembered that all of the above factors also adversely affect the state of flora and fauna, both present and future. For example, pollution of water bodies, destruction of forests, etc., entails the disappearance of the diversity of flora and fauna that our ancestors used to see. Even over the last hundred years, the species abundance has significantly decreased under the direct or indirect impact of the anthropogenic factor.

Earth's protective shell

If the question arises: "What environmental problems of the planet are currently known?", then holes in the ozone layer are easily remembered. Modern human economic activity involves the release of special substances thatcause thinning of the Earth's protective shell. Consequently, the formation of new so-called "holes", as well as an increase in the area of existing ones. Many people know this problem, but not everyone understands how all this can turn out. And the destruction of the ozone layer leads to the fact that dangerous solar radiation reaches the Earth's surface, which negatively affects all living organisms.

Desertification

The global environmental problems presented earlier are causing the development of a major catastrophe. It's about desertification. As a result of improper agriculture, as well as pollution of water resources and deforestation, there is a gradual weathering of the fertile layer, drainage of soils and other negative consequences, under the influence of which the land cover becomes unsuitable not only for further use for economic purposes, but also for living. people.

Depletion of mineral reserves

A similar topic is also on the list of "Ecological problems of the planet". It is quite easy to list the currently used resources. These are oil, coal of various varieties, peat, gas and other organic components of the solid shell of the Earth. According to scientists, in the next hundred years, mineral reserves will come to an end. In this regard, humanity has begun to actively introduce technologies that work on renewable resources, such as wind, solar, tidal andother. However, the use of alternative sources is still quite small compared to more familiar and traditional ones. In connection with this state of affairs, modern governments of countries are conducting various incentive programs that contribute to a deeper introduction of alternative energy sources both in industry and in the everyday life of ordinary citizens.

Overpopulation

Over the past century, there has been a significant increase in the number of people on the globe. In particular, over a period of just 40 years, the world's population has doubled - from three to six billion people. According to scientists, by 2040 this number will reach nine billion, which, in turn, will lead to a particularly acute shortage of food, water and energy resources. The number of people living in poverty will increase significantly. There will be an increase in deadly diseases.

MSW

In the modern world, a person produces several kilograms of garbage every day - these are tin cans from canned food and drinks, and polyethylene, and glass, and other waste. Unfortunately, at present, their secondary use is carried out only in countries with a highly developed standard of living. In all others, such household waste is taken to landfills, the territory of which often occupies vast areas. In countries with a low standard of living, heaps of garbage can lie right on the streets. This contributes not onlysoil and water pollution, but also increases the growth of disease-causing bacteria, which in turn leads to widespread acute and sometimes fatal diseases. It should be noted that even the Earth's atmosphere is filled with tons of debris left after the launch of research probes, satellites and spacecraft into the vastness of the Universe. And since it is quite difficult to get rid of all these traces of human activity in a natural way, it is necessary to develop effective methods for processing solid waste. Many modern states are implementing national programs that promote the spread of easily recyclable materials.
