Our Planet - this is our home.It provides human food, heat resources.It has everything you need for a fulfilling life.But human activity is destructive force, which leads to global disturbances of the world.Today, with the naked eye you can see how nature has changed during the lifetime of a person, because the consequences are reflected in the quality of life of these same people, the environment, flora and fauna.
Why delve into the issue
known that in order to solve the problem, you need to understand the root of the problem.This principle is effective in this case, it is important to prevent the pollution of the planet, but not eliminate the consequences.If there is no power, ruining the environment, our earth would be able to recover.But in order to give the result of action, you must first learn how to change the nature of human existence in the time and what factors disrupt the balance of the ecosystem.
Species influence
human impact on nature can be intentional.In this case, to meet the needs of society produced the mass deforestation, built waterworks and other facilities or mined resources to the detriment of nature.
In addition, the harm can be applied inadvertently, for example, developed the place of extraction of resources formed in man-made landforms, and processing of resources leads to pollution of the atmosphere.
natural world also suffers from the indirect and direct human impact.From irrigation fertilizer in the soil of entire fields occur negative changes (direct effect).Broken the chain of metabolic processes involve further disruptions in the ecosystem (indirect).
negative impact
impact of human activity on the biosphere is essential because of the impact of our world as we know it today.It may be noted several negative aspects of how to change the nature of the existence of man:
- disappeared many forest areas.The main role of trees - a "struggle" with carbon dioxide.Due to this property, the trees should soften the climate, but as forests become smaller, the weather around the world much changed.In addition, the hillsides, left without trees, doomed to erosion, which leads to the collapse.
- are polluted waters of the earth, its atmosphere and the surrounding nature.
- depletion of the soil.To increase the productivity of the fields, use chemicals and pesticides, which are taken from the latest ground minerals.To the soil was able to recover the lost balance, required decades.
- disappeared many species of flora and fauna.The activity of people has changed the ecosystem to which some species could not adapt.Others have been destroyed by man.Also, many of the animals suffered from the indirect influence of human activities.So, the natural world has been subject to deforestation due to the increased needs of the person, causing many types of flora have lost their habitat and killed.
- depletion of resources, which were formed millions of years.Generating unprecedented rates of coal, oil and other deposits lead to the fact that even after 100 years, mankind will be left without these vital resources.
ponds, oceans
This is certainly not an exhaustive list of examples of how to change the nature of the existence of man.Almost all rivers that pass by the towns subjected to ruinous pollution.Also do not forget about the oil that constantly gets in the water.Just one drop of making unsuitable 25 liters of water, and the oceans are constantly get tons of oil.
In addition, each year the mankind emits tons of garbage, which is dominated by plastic.Ultimately, the majority of waste that can not be decomposed into minerals, find their "peace" in the world's oceans.Already much is known about the "dead zone", which is located in the Pacific Ocean.This is debris that floats on the water surface and occupies a vast territory.Each year, a "dead zone" is replenished with tons of fresh garbage.From the height of the helicopter this "dump" like a big island.Such floating debris does not allow light and air to reach the sea creatures.Some species can not find a new home and die.
