3 The word "ecology" ("Ökologie") was coined in1866 by the German scientist Ernst Haeckel(1834– 1919). Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics. Ancient Greek philosophers such as Hippocrates and Aristotle laid the foundations of ecology in their studies on natural history. Modern ecology became a much more rigorous science in the late 19th century. Evolutionary concepts relating to adaptation and natural selection became the cornerstones of modern ecological theory.1866Ernst HaeckelHippocrates Aristotlenatural historyscienceEvolutionarynatural selection ecological theory

4 Ecological problems In early days of mankinds history people lived in harmony with the wild nature. They were a part of this environment. But years were going forward and people created their own civilization and rules of live. They began explore the planet and use its resources more and more. But this interference was harmful for the environment. Needs of people were increasing and natural riches wasnt unlimited. Mankind began to build big cities and burn out forest. It was the reason of disappearing of many wild animals, fish and birds. Many factories spoil water and air of our planet with dust and harmful substances. The development our civilization destroys the explosion of Chernobyl Atomic Power Station. It isnt the only case of mens activity which brings damage to the environment. But we mustnt forget about the fact that we all live in the planet which we are destroying. We drink dirty water and breathe in a poisonous air. We kill ourselves when destroy wild nature around us. Now people see this great ecological crisis of our planet. So different organizations such as "Greenpeace do everything possible to save the environment.

20 We depend on the Earth so we better start taking care of it. Every day we are given the option to make positive change for the future of our planet. Dont ever let someone tell you that one person cant make a difference! The truth is that for centuries it has always been the action of one person that inspires the action of many. Be a leader in your community and do what you can to reduce the misuse and overuse of our natural resources. We are not entirely to blame; we inherited a polluted Planet Earth and are seeing the consequences of the decisions made by previous generations. Luckily we have all the tools we need to ensure that our children can grow up in a cleaner, safer planet than ourselves! Making a difference for the future of Planet Earth doesnt have to include huge life changing choices!! Some of the most important things are simple lifestyle changes that, if we can all commit to, will create a huge reduction in our ecological footprint.
