The environmental footprint per capita in developed countries is more than 10 tones per year. For example, 10,8 tones of carbon is emitted per capita by British, 12,7 per capita by Greek and 22,4 tones per capita by Americans. It takes both governments and the citizens to take measures to reduce the impact of each nation on Earth. Many every day habits need to be reconsidered and altered drastically.
19.312 Kilometers an average car travels per year, producing 6 tones of greenhouse gases. But you would have to travel 150.107 Kilometers by train to produce the same amount of carbon for the same period. At the same time, 18 times more carbon is emitted per mile per passenger in a car than in a bus. Buses emit less carbon per passenger than trains, planes, boats or automobiles (in that order). In 2007, of the European Union’s total CO2 emissions, the 12% was created by passenger cars.

A new scientific study from the National Oceanic and Atmospheric Administration (NOAA) in USA shows that “there’s no going back” from climate change caused by carbon dioxide. The study, led by NOAA senior scientist Susan Solomon, has reached the shocking conclusion that the effects of man-made climate change are largely irreversible for more than 1,000 years after carbon dioxide (CO2) emissions are completely stopped.
“Our study convinced us that current choices regarding carbon dioxide emissions will have legacies that will irreversibly change the planet,” said Solomon, who is based at NOAA’s Earth System Research Laboratory in Boulder, Colo.
“It has long been known that some of the carbon dioxide emitted by human activities stays in the atmosphere for thousands of years,” Solomon said. “But the new study advances the understanding of how this affects the climate system.”

Right after the industrial revolution, the exploitation of natural resources by human societies increased at top speed. Fossil fuels are ever since the main source of energy used to cover most of our needs. This made people believe that they do not depend on renewable energy, but can survive only by using old technological inventions.
However, as it takes millions of years for fossil fuels to be created, being extracted in such an alarming pace means that we will sooner or later run out. Only then will people realize how much we wrongly depend on them. Production of all kinds of goods, heating and transportation are only few of the fields that will be directly affected.
But even if fossil fuels were an infinite source of energy, they are the main reason why huge quantities of carbon dioxide accumulates in the atmosphere, causing the greenhouse effect as well as acid rain, breathing problems and destruction of natural habitats.
Concequently, scientists should concentrate on creating and improving the ways we use alternative sources of energy. Making these sources more effective and easy to use, humanity will be able to wean off fossil fuels and face climate change. Generous fundings are given to laboratories dealing with medical care and weaponary. It is time that we realise that fossil fuels should not play the dominant role in producing energy, and thus major steps should be taken.
