Main global environmental problems, each of which can destroy humanity
What is the main danger to human life? Wars? A supervolcano eruption? Collision with a comet?
The life of the average person today is filled with comfort. He travels long distances by private car, plane or train, his diet consists of a variety of foods and his health is monitored by a whole army of doctors who constitute a unique health system. But this is only at first glance. In fact, each of us constantly faces serious risks that we may not even realize. We talk about global environmental issues.

The inhabitants of the metropolis are particularly concerned by the problem of air pollution. Huge volumes of exhaust gases, corporate emissions envelop cities in a thick layer of smog, in which it sometimes becomes simply impossible to breathe. Hence the many health problems in adults and children.
Sources of environmental pollution:
- operation of industrial installations;
- gasoline vapors from vehicles;
- radioactive elements;
- Agriculture; household and industrial waste.
Lack of drinking water
The population of the arid regions suffers cruelly from a lack of drinking water. Endless epidemics, chronic diseases, social tensions and territorial disputes over water sources force them to leave their homeland and seek a better life. The consequences of water scarcity have already been felt by Europeans, when the streets of their cities have been flooded with migrants from Africa and the Middle East.
- The growth of the human population means more people, respectively, they need more water for drinking and for hygienic needs.
- A large number of industrial installations that consume water in large quantities both as a raw material and as a cooling agent. And what about agriculture – in addition to irrigation, a large amount of water is spent on raising livestock and poultry. It’s hard to believe, but to produce 1 kg of beef, you have to spend 15,000 liters of water!
World ocean pollution
For several years, the environmental scientific community has been looking for technologies to solve a problem such as the pollution of the world’s oceans by plastic waste. At present, five huge islands of waste have been discovered which are drifting in the waters of the Pacific, Atlantic and Indian oceans and pose enormous risks to all their inhabitants.
Some animals and fish mistake plastic microparticles for phytoplankton and eat them by mistake. Seabird chicks are attracted to larger pieces of brightly colored plastic, young birds swallow them, dooming themselves to a painful death. At the moment, no effective way out of this situation has yet been found. However, new concepts and ideas are constantly being offered to experts.
- The greatest pollution started after the development of coastal areas. 60% of cities are located near seas and oceans. As a result, the aquatic environment is polluted by household waste. The “weak zone” of coastal settlements are the ports. Uncontrolled mass fishing is destroying ocean ecosystems. This leads to a deterioration in the condition of the banks. Fishermen, ship captains and workers in other maritime professions contribute to the pollution of the world’s oceans.
- Most petroleum products are transported by water. Although accidents on cargo ships and oil pumping devices are rare, they are of great magnitude. A malfunction of an oil rig can lead to the spillage of millions of tons of raw materials. As a result, stains form on the surface, which are extremely difficult to remove.
- The vast majority of waste arrives directly. People themselves throw parcels, bottles, food into the seas. Part of the waste enters the aquatic zone through sewers, rivers. To a greater extent, water pollution is caused by such substances:
- oil products;
- solid household waste;
- Plastic; fertilizers;
- waste water discharges;
- toxic chemicals.
Destruction of the ozone layer
Another problem facing humanity is the destruction of the ozone layer. Ozone, located at an altitude of 20-25 km above the Earth’s surface, is a kind of filter that absorbs the Sun’s aggressive ultraviolet rays. With the thinning of the ozone layer, people massively lose their eyesight, get sunburn, which subsequently leads to the development of malignant skin tumors.
In addition, marine ecosystems are threatened, because phytoplankton, acting here as the main link in the food chain, cannot develop normally under excessive exposure to aggressive UV radiation. The solution to this problem lies in the rejection of the use of freon gases, which most actively destroy the ozone layer.
- launching rockets and satellites into space;
- operation of air transport at an altitude of 12-16 kilometers;
- freon emissions into the air.
