MAN AND ENVIRONMENT

“If we surrendered to earth's intelligence we could rise up rooted, like trees. ”

The dictionary defines man as an adult human male and environment as the surrounding or conditions in which a person, plant or an animal lives or operates. The combination of these two words is a complex and an ever-changing relationship. Man has a massive impact on the environment. With the negative overshadowing the positive by a great deal.

The most noticeable and alarming environmental change that all humans experience is the drastic weather cycles. Does the summer seem hotter than it was last year? Does it seem like the monsoon has given up on a schedule and does just as it pleases? Does it seem weird that there are freak storms and floods? Do you see the green cover rapidly shrinking on Planet Earth and the pollution levels rising? All this is a result of our deteriorating environmental conditions. The biggest cause being global warming- the root of all other causes.

The current environmental problems our Planet Earth is facing include ozone depletion, pollution, loss of natural resources, nuclear problems, loss of biodiversity, energy crisis, improper waste management and the biggest of them all, global warming.

Chlorofluorocarbons (CFCs) are considered to be the main cause of ozone depletion. The term ozone depletion implies a decline in the quantity of ozone in the earth's stratosphere. The loss of ozone in the lower stratosphere was first recorded in Antarctica in the 1970s. As we know, the earth's atmosphere is composed of many layers; ozone forms one such layer in the stratosphere. CFCs are used in aerosol sprays as well as air conditioners. These, when released into the atmosphere add to the ozone depletion. The ozone hole in the Antarctic is caused primarily due to these CFCs. Due to ozone depletion; humans are faced with various other problems such as dealing with the harmful effects of UV rays. These affect not only humans, but also affect plants and various species of animals as well.

Pollution is something that we face on an everyday basis. It is probably a problem that we may have become immune to, given our fast-paced lives and the fact that it is being treated as a hackneyed issue, where a lot is spoken about but nothing concrete is ever done. Pollution can be divided into four main categories: air pollution, water pollution, soil pollution and noise pollution. Air pollution occurs with the addition of harmful chemicals into the earth's atmosphere. The main pollutants of air are carbon monoxide, CFCs (Chlorofluorocarbons), nitrogen oxides and sulfur dioxide. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Water pollution is caused when wastes are released into the water and contaminates it. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. Soil pollution takes place when the soil is contaminated due to various industrial activities. It has been mainly attributed to urbanization and industrialization, both of which destroy natural resources that are already present in order to build and become successful. Noise pollution occurs when the noise levels (honking, loud speakers, etc.) crosses the normal decibel level. This can have a harmful effect on one's hearing and lead to more severe after-effects, both physical and psychological (fatigue, irritation, stress, etc.). With the alarming rate of increase in population, the loss of natural resources has become one of the major concerns. Issues like deforestation, animal...
