Human beings attitudes contribute to damage the environment

It’s scientifically proved that human’s beings are not the cause of the damage of the environment. A cycle described by Milankovitchexplained the effects of chances in the Earth's movements upon its climate. However, it’s not an excuse to the people unconscious.
What is has been denominated astronomical theory of glaciations isexplained in a perfectly way by Milankovicth Theory. It shows how the climatic patterns are determinate by variations in eccentricity, axial tilt, and precession of the Earth's orbit.
“The Earth's axiscompletes one full cycle of precession approximately every 26,000 years. At the same time the elliptical orbit rotates more slowly. The combined effect of the two precessions leads to a 21,000-yearperiod between the seasons and the orbit. In addition, the angle between Earth's rotational axis and the normal to the plane of its orbit, obliquity, moves from 22.1 degrees to 24.5 degrees and backagain on a 41,000-year cycle; currently, this angle is 23.44 degrees and is decreasing.”
It’s explains the global warming and all the climate variations that the earth is having.
Nevertheless,environmental contamination is caused by another factor, the anthropogenic influence on climate.
Technological and exponential demographic increasing threatens the biological equilibrium of the earth.Industrial goods, commercial, agriculture, house hold and sources mobile are the sources produced by human’s beings that generated more pollution.
Carbon dioxide and greenhouse gases are contributing tothe global warming. The destruction of ozone due to human activities has become so dangerous, because has reached the point where the sun's harmful rays, ultraviolet B, come inlarge parts of the earth’s surface at levels capable of causing extensive damage to life.
The increasing doses of UV-B threaten the health and human welfare, crops, forests, plants, wildlife and marine. There has been a...
