Human beings form an integral part of society and have the greatest impact on our environment.
Human beings form an integral part of society and have the greatest impact on our environment. They have resourcefully influenced every facet of life on earth. It helped shape the evolution of humans, right from the very first human ancestors to our modern-day selves. And we have indeed come a long way – almost 2 million years of evolution. From advancements in the social behaviour of man to achieving new feats every day in the fields of science, technology, and medicine, we have tremendously explored and still paving a way to find better ways to deal with real-time problems to provide the society with a better standard of living.
While we would have greatly contributed to the well being of our society, we have overlooked or neglected the fact that eventually, we have been playing up with the environment in which we stay. This has been showing up in recent times in the form of global warming , floods, cyclones, tsunamis etc which are a few consequences of various activities of man. Few are:
Let us understand two of these environmental issues in detail.
Three atoms of oxygen make up a molecule of Ozone(). While , oxygen gives life to organisms, ozone is a poisonous gas. It may be hazardous on earth, but up in the different atmospheric levels, Ozone plays a vital role. UV rays are given out by the sun and cause damage to organisms, skin cancer in human beings to be precise, hence are dangerous. Ozone blocks these UV radiations from reaching the earth.
At the atmospheric levels, Ozone is a product of UV rays acting on a molecule of oxygen (O 2 ), these rays cause oxygen molecules to split up into free atoms of oxygen (O). Free oxygen atoms then combine with molecules of oxygen to form ozone (O 3 ), look at the equation below to understand better-
Over the years, this protective layer around the earth has been depleting. A sharp depletion was discovered way back in the 1980s which are caused due to CFCs (chlorofluorocarbons) used in refrigerators and fire extinguishers. This is why it is now mandated on manufacturing companies to make CFC-free appliances throughout the world.
The process of treating solid wastes by gathering, transporting and disposing of garbage is called waste management. Wastes can either be biodegradable or nonbiodegradable.
Biodegradable wastes are acted upon by biological processes which help in their break down but non-biodegradable substances are not broken down by these biological activities. They exist in nature for a long time and prove to be hazardous in the long run, hence treating them is very necessary.
The activities of human beings are so impactful on the environment that suitable measures need to be taken. Few are:
