Climate change and protection of our environment
Air pollution probably already started with the industrial revolution around 1750. One reason why we are now confronted with such alarming effect of global warming, is that this process does not follow a linear (e.g. 1,2,3,4) but exponential (e.g. 1 2,4,8,) function. Changes are multiplied with the same number with each step in time. And its dramatic manifestations, such as melting glaciers permafrost and ocean ice are not something that can be restored in a couple of years or decades. Even in the unlikely event that fossil fuel depletion and CO2 emission would now be drastically reduced, its beneficial effects would probably still take many generations to become manifest.
Nevertheless, the climate models although realistic, should not lead to despair. Because there is something we can do on the short term and that is protecting the parts of the environment that we cherish and want to preserve for future generations. This can only be accomplished if we change the mentality of our leaders of industry and their political allies. And convince them that a healthy economy should go hand in hand with environmental protection not destruction.
