Evidence of the greenhouse effect is already evident today — polar melting, tsunamis, heat waves, and flooding are in the front pages of every newspaper.

So now lets discuss the Arctic Polar Bears along with climate change. The ice is melting at an astonishing 9% per decade. Some ice caps have been around for thousands of years, and have only begun to melt in recent times. This melting of the arctic causes displacement of the polar bear population into more temperate areas, where survival is more difficult for them. There are already reports of polar bears being seen wandering around beaches and near whale kill sites. According to a recent study, polar bears may be extinct in the next century due to the rapid decrease of arctic landmasses.

This is a cause of worry for biologists and environmentalists because of the role that polar bears play in the food chain. They are primarily the top predators of the arctic region, feeding largely on seals. A decrease in polar bear population would lead to overpopulation of seals. Seals feed on fish, and their increase in number would lead to decrease of fish population. Since fish eat algae, a decrease in fish population would amplify algae production which would in turn increase oxidation in the water, ultimately affecting water biosphere.

As long as we remain to ignore the telltale signs of global warming and carry on with our lifestyle without thought of our carbon emissions, we will continue to see seemingly small climatic changes which will turn disastrous if not acted upon. To act now is crucial to our survival and the most important gift that we could give to future generations.  Don't ignore this problem because we live in a tropical country and could care less.. let your voices be heard !!!
