What happens to our earth? I warn you, this is not nice to watch!
Do not worry, nothing happens.
It’s just another bag, another sorbet, a plastic cup, a bath, a diaper, a bottle, a wrapper, a card ...
And so with you millions more other people think
Pollution (of the environment, environment, biosphere) is the introduction into the environment (environment, biosphere) or the emergence of new, usually non-characteristic physical, chemical or biological agents (pollutants) in it, or the excess of their natural long-term average in various environments leading to negative impacts.
When determining the main subject, anthropogenic and natural pollution are distinguished. The main objects are - soils, atmosphere and reservoirs. Classification by type of pollution is based on four components: mechanical, physical, chemical and biological. While classifying by scale, local, regional and global pollution [
- Biological - pollutants are organisms, the introduction and reproduction of which is undesirable for both humans and ecosystems in general. Penetration can go the natural way, and in some cases is a consequence of human activity. As a component, microbiological contamination is isolated.
- Mechanical - pollution of chemically and physically inert garbage in the environment, which, as a rule, leads to a deterioration in its quality and affects the organisms living in it. In reality, mechanical pollution occurs in conjunction with physico-chemical effects.
- Physical - a pollutant leads to a change in the physical parameters of the environment, including temperature and energy (thermal pollution), wave (light, noise, electromagnetic pollution), radiation (radioactive pollution) and some others.
- Chemical - a pollutant leads to a change in the natural chemical properties of the medium, expressed in an increase in their concentration, or to the penetration of substances that were absent in the medium before. An example of chemical pollution is aerosol.
It got too dirty on the planet
It is interesting to know which house we live in? Our home is planet Earth, where the air we breathe, the water we drink, the earth we walk on and feed us. Many people are completely mired in their work, entertainment, and see nothing around. Although, it is time to open our eyes and see that our house is close to destruction. And no one is to blame, except for each of us.
American environmental researchers studied natural change for 6 years. After the expiration of the deadline, they declared that it is no longer possible to live in cleanliness; everything that is possible is contaminated on the planet.
Thanks to a study worth six million dollars, it was possible to find out that toxic waste from industrial activities had already polluted everything. According to scientists, in the territory of 20 US national parks there are at least 70 types of toxic substances.
Michael Kent, a natural science professor at the University of Oregon, condemns the dirty intentions of toxic substances to pollute everything on which the light stands. "It is difficult to find more remote areas than the northern regions of Alaska and the peaks of the Rocky Mountains, but even there we found pollutants," the scientist explains.
Meanwhile, the United States is the leader in industrial air emissions. In second place are Saudi Arabia and Indonesia. At the last, Bali Conference, all three countries were honored with antipremises for not being able to keep the area clean. In the role of the award were small, stuffed with coal, bags of colors of the national flag.
To solve the environmental problem at the state level in the world is not accepted. So, according to the research of the Carbon Disclosure Project, only commercial structures solve the problem of atmospheric emissions, while state authorities cut good intentions in the bud. In numbers, 80% of companies see climate change as a significant risk to doing business. And they realize the seriousness of the situation and work on its solution - 95% of commercial organizations.
The greatest garbage dump on the planet
In the Pacific Ocean, “soup made of plastic” is growing terribly fast - a floating strip of garbage, and, according to scientists, at this point twice the size of the continental United States.
Back in 2004, the “island” weighed about 3 million tons — six times the amount of natural plankton. And the size corresponded to the territory of Central Europe. Four years later, the "island" afloat noticeably "recovered."
This huge pile of floating debris is held in one place under the influence of underwater currents with turbulences. A strip of soup stretches from a point approximately 500 nautical miles off the coast of California through the northern Pacific Ocean past Hawaii and almost reaches remote Japan.
Actually, the “soup” - these are two areas connected by a jumper on both sides of the Hawaiian Islands - they are called the West Pacific and East Pacific garbage spots. About a fifth of the garbage - various differences from soccer balls and kayaks to Lego blocks and plastic bags - is what is thrown from ships and oil platforms. The rest falls into the ocean from land.
The American oceanologist Charles Moore, the pioneer of this "great Pacific garbage spot", also known as the "garbage cycle," believes that about 100 million tons of floating rubbish are circling in this region. He warns that if consumers do not limit the use of plastic that is not recycled, the surface area of the plastic “soup” will double in the next ten years. This is due to the fact that modern plastic practically does not give in to decay, and objects of as much as half a century ago are found in the North Pacific dump.
As a result, it turns out like this: “What enters the ocean is in the stomachs of the ocean inhabitants, and then on your plate. Everything is very simple.”
Only 4% of the world's waters remained unpolluted by humans. As the new atlas of the ecological state of the oceans shows, ten times large areas were strongly affected. The most unexpected was that different types of human activity, combined, cause significantly more damage to biodiversity than their simple addition predicts.
Human activities - fishing, the release of industrial and household waste, mining, and so on - have left an indelible mark in almost every corner of the world's oceans. These are the conclusions of a new large-scale study, which for the first time allowed the creation of a map of world waters, reflecting the degree of human intervention in natural ecosystems. Scientists have discovered that today there are practically no water areas not affected by the life of the king of nature, and 40% of the world's waters have been severely harmful.
As a result of large-scale research work, mankind for the first time was able to see the whole picture of the consequences of its work on the development of what seemed to be the inexhaustible wealth of world waters. The supervisor, Ben Halpern, a researcher at the University of California at Santa Barbara, emphasizes that the resulting map of ocean pollution reflects the cumulative effect of various types of human activity. The total effect of these effects turned out to be much worse than one could imagine by simple addition, and was an unpleasant surprise for Halpern himself.
Every year, accidentally or intentionally, hundreds of tons of oil and fuels and lubricants enter the oceans. The world's most harmful effects on the part of the world were in the North, South and East China, Caribbean and Mediterranean Seas, ecosystems of the Red and Bering Seas, as well as the Gulf of Mexico, were severely damaged. A similar situation is observed along the entire eastern coast of the North American continent, as well as in the eastern part of the Pacific Ocean. Polar waters were least affected. However, due to the melting of the polar ice caps, they too will soon be in danger.
Scientists note that different ecosystems have been affected by humans to varying degrees. So, about half of the coral reefs today are on the verge of extinction, and the situation with thickets of seaweed - Posidonii, seaside, water-red and many others - is difficult. Things are bad with mangroves, ecosystems of the shallows, rocky reefs and on the continental shelf. The bottom ecosystems and inhabitants of the open ocean are least affected today, but in most places they have also experienced human impact.
