You need to know what the problems are, where the problems are and how they will impact our future
.
Knowledge is power and the only way change will happen is with knowledge. The more we know about the complex and interrelated systems involved such as the ecosystems, the more likely we are to make the right choices.
While just about every ecosystem on the planet is threatened in some way by pollution perhaps none is less understood and clearly threatened than the polar ice caps.It has been clearly established that the ice caps are melting are the result of air pollution. It is also known that over the years the ice caps have trapped other pollutants that have been deposited there in the form of ice and snow. As the melting occurs these toxins are then released into the waters of the world and ready to react with biological organisms the world over.
Pollution from all its many and varied sources is responsible for the extinction of many species.When even one species disappears,it can set off a chain of events that has profound ramifications. A study concerning the removal from Olympic National Park in the State of Washington resulted in a series of events that rerouted rivers and affected the viability of salmon populations by changing the population and grazing habits of their former prey.
The loss of even one species or factor can change everything in such a manner that it may take tens of thousands of years to fully repair the associated environmental damage.
A lack of habitat is the leading cause of extinction pressure and is a direct result of human expansion into these previously wild areas.
Pollution is not only destroying the ozone layer that protects us from the ultraviolet rays of the sun but is producing carbon dioxide in such large quantities that it is causing the polar ice caps to melt.This in turn exposes more of the earths surface to the rays of the sun and increases the overall temperature of the earth thus causing climate change.
