From time immemorial, mankind in its essence has been striving for a state of security, security and is trying to create the most convenient and comfortable living conditions.
On the other hand, all life is constantly in the world of a wide variety of risks. The threat is present everywhere and comes from everywhere: from criminogenic situations, from rulers, from accidents, from the risks of various infections, from the risks of military conflicts, and many more. other
The safety of the planet and therefore of all mankind is the main problem of our time.
The main types of danger to the planet
The development trends of the main types of disasters (environmental, natural and technological) show that on Earth in the coming years a high degree of probability of the occurrence of major emergencies will remain. An increase in the number of such disasters will lead, respectively, to an increase in damage, which is already huge today.
It is important to note that a characteristic feature of these types of dangers and threats today is their complex interconnected nature, which is expressed in the fact that one disaster can cause a whole chain of others and even more catastrophic ones. The safety of the planet is the most serious issue today.
Ecological disasters
From the very beginning of human development of vast territories of the planet, many major environmental disasters occurred, representing the most global problems of our time.
Irreversible changes are occurring in the world of natural resources and resources, leading either immediately or over time to the death of many living creatures.
There are 4 types of catastrophes in total - global, local, man-made and natural.
Environmental safety is one of the most important issues today.
The biggest problem arises precisely in man-made accidents. And humanity is completely to blame. More often this type of danger is local in nature, but its consequences are worse than many more global problems.
Especially serious are accidents at nuclear power plants, in connection with which the ecological safety of the planet has become more likely a pipe myth than a reality.
Natural hazards
On the surface of the Earth and in the nearest atmospheric layers, complex processes (physico-chemical and biochemical) occur, accompanied by the exchange of energy of various kinds. The sources of these energies are the processes occurring in the bowels of the Earth, the chemical and physical interactions of its outer shells and physical fields.
A person cannot suspend or change the course of such transformations; he is only able to predict their development and influence the dynamics.
Global warming is the greatest danger threatening the planet and all of humanity. According to skeptics, people's activities, quite possibly, play a role in shaping this disaster, but not decisive. However, the safety of the planet to some extent also depends on the activities of people.
The most common phenomena are those associated with exogenous, endogenous and hydrometeorological processes. Endogenous include tectonic phenomena (earthquakes, etc.). Hydrometeorological - tornadoes, floods, hurricanes, typhoons, snowfalls, heavy rains, frosts, etc. Exogenous are associated with gravitational processes (landslides, landslides, mudflows, snow avalanches), underground (subsidence, karst, swelling) and surface (abrasive) erosive) waters.
