Global Environmental Changes

Human beings are now causing real alterations to the environment on a huge level by changing landscapes, the atmosphere, and the oceans. Our knowledge in the attempt to comprehend the changes has evolved from pure research, mostly in the physical sciences, with the goal of understanding climate change directed towards a field of science that works , hand in hand, with other sciences such as ecology and the various social sciences. The field of studying global environmental changes focuses on the accurate categorization of the weakness and flexibility of ecosystems, that are either natural or managed, and the effects of human societies on the global change.

The Industrial Revolution and the continuous growth of human population on the planet led to more destruction of major areas of forest cover and to an increasing need to eliminate forests for agriculture and for the required expansion of cities and urbanized zones. Another point causing the changes is the increase of atmospheric temperatures as a result of the amounts of carbon dioxide that is being emitted continuously into the planet’s atmosphere resulting in what is commonly known as global warming.

Another global change in environment is the decline of fish stock. The Decline of fish stocks is mostly related to a wide range of human activities, and again we find that the growth of human population and the extended life spans of human beings in the last few decades have contributed enormously to the decline of fish stocks as commercial fishing has increased to a very large extent.

Numerous approaches to solve these problems have been developed by now, but any of them could considerably better the situation.
