From time immemorial, humanity by its very nature strives for a state of security, security and tries to create the most convenient and comfortable conditions for life.
On the other hand, all living things are 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 others. others
The security of the planet and, accordingly, of all mankind is the main problem of our time.
The main types of danger to the planet
Trends in the development of the main types of disasters (environmental, natural and man-made) show that a high degree of probability of major emergencies will remain on Earth in the coming years. An increase in the number of such cataclysms will lead, accordingly, to an increase in damage, which already todayhuge.
It is important to note that a characteristic feature of these types of dangers and threats today is their complex interrelated 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.
Environmental disasters
From the very beginning of human exploration of the vast territories of the planet, many major environmental disasters have occurred, which are the most global problems of our time.
Irreversible changes in natural resources and resources are taking place in the world, leading either immediately or over time to the death of many living beings.
In total, there are 4 types of disasters - 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 for this. More often than not, this type of danger is local in nature, but its consequences are worse than many more global problems.
Especially serious accidents at nuclear power plants, in connection with which the environmental safety of the planet has become more likely an unrealizable myth than reality.
Dangers of nature
On the surface of the Earth and in the layers of the atmosphere closest to it, the most complex processes (physicochemical and biochemical) occur,accompanied by the exchange of energy of various types. The sources of these energies are the processes taking place in the bowels of the Earth, the chemical and physical interactions of its outer shells and physical fields. A person cannot stop or change the course of such transformations, he can only predict their development and influence the dynamics.
Global warming is the biggest danger threatening the planet and all mankind. According to skeptics, the activity of people, quite possibly, plays a role in the formation of this disaster, but not decisive. However, the safety of the planet to some extent depends on the activities of people.
The most common phenomena are those associated with exogenous, endogenous and hydrometeorological processes. Among the endogenous are 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), the action of underground (subsidence, karst, swelling) and surface (abrasive, erosive) water.
Man-made threats
The safety of the planet also depends on man-made threats. People learned and realized this kind of danger later than natural ones. Why? Because these events (technogenic disasters) were facilitated by the accelerated development of the technosphere. The sources of disasters were terrible man-made disasters.
It is important to note that objects andstructures are divided into the following groups:
- Nuclear, biological, chemical weapons and defense facilities. These are all weapons of mass destruction.
- Nuclear power facilities.
- Space-rocket complexes.
- Biotechnological and chemical complexes.
- Oil and gas complexes.
- Energy facilities.
- Metallurgical complexes.
- Gas and oil pipelines.
- Various structures (dams, bridges, stadiums, etc.).
- Constructions for civil and industrial construction, etc.
Our planet is huge and beautiful. Her safety is in danger. All mankind should take seriously the above global problems and live in such a way as to preserve all the riches bestowed by the generous nature of the Earth, and thus try to save the planet itself.
