The ecological situation in the world

   From the very beginning, man interacted with and influenced the environment.  However, this effect reached its true scale only in the XVIII century, with the beginning of the industrial revolution.  At this time, man abandoned the natural cycle of wildlife and began to tell the planet its rules.

   The planet began to change, but we immediately noticed - our civilization was engaged in other activities: mining (coal, gas, shale, oil), metals and other minerals.  All these substances, which man naturally receives and stores, have returned to nature, but in a different way.  This has become a global pollution of soil, water and air, causing an environmental crisis.  And the intensity of this process is growing at an alarming rate, and humanity will soon have to deal with the severe consequences of the environmental crisis.

   The difficult political situation of the twentieth century (the collapse of the world community and world wars) did not help mankind to pay attention to environmental issues.  Add to this the arms race (the Cold War), social inequality in countries and the incredible speed of technological progress.  At the end of the twentieth century, all these factors made mankind calm down, look back and realize how much damage they have done to their homes.

   Types of environmental problems

   1. Global warming, in fact, is a by-product of the existence of a huge human population.  Simply put, this is a general increase in the temperature of our planet due to human activities (such as burning fossil fuels).  As a result - melting glaciers, rising sea levels, excessive rainfall, acidification of the ocean.

   Not all out-of-context processes seem particularly scary.  However, it should be remembered that the Earth is a very thin and delicate system, where all connections are interconnected.  Such a large-scale intervention destroys this system and leads to negative consequences - leads to seismic activity and extinction of all species of animals.

   2. Ocean pollution.  More than half of our planet (70% to be exact) is water.  The ocean is a key factor in shaping the Earth's climate: currents cause heat or cold, and evaporated water forms clouds and precipitation.

   About a hundred million people live near the ocean, which means that their lives are directly related to water bodies.  But in reality, the oceans affect the lives of each of us in one way or another: rain and other precipitation;  delivery of goods between continents;  Fish and other seafood that we eat every day.  However, today the world's oceans are threatened by constant man-made disasters (tanker accidents, etc.), dumping of wastewater and industrial waste into the ocean.

   3. Destruction of the ozone layer.  Ozone is one of the components of the stratosphere (at an altitude of 12-50 kilometers), it is one of the types of oxygen.  The value of ozone for humans is that it blocks part of the ultraviolet rays and protects all living things from direct sunlight.

   Although humans have been harmful to the ozone layer for centuries, our science has only recently discovered the existence of ozone.  As a result, holes are formed in the ozone layer due to lack of substances.  Among the causes of this phenomenon are:

   International Space Program.  Launch of rockets and satellites;

   Flights from twelve kilometers and above;

   Freon industrial and domestic emissions.

   In the eighties, humanity began to take the first steps to protect and restore the ozone layer.  Environmental programs have been adopted at the state level, and global nonprofits have begun to develop ozone protection projects.  Unfortunately, such measures are very expensive and rarely find full funding.
