UNIT 1 ECOLOGY AND THE ENVIRONMENT
1.1 INTRODUCTION TO ECOLOGYStudy the information about ecology and the environment and answer the questions after.
Speaking of the natural environment, we use the term ‘ecology’. This word was introduced in 1869 by German biologist Ernst Haeckel (1834-1919) for the science studying the relationship of organisms with their environment. This word came from Greek ‘oikoş’ which means ‘home’. The idea of home includes our whole planet, its population, nature, animals, birds, fish, insects and all other living beings and even the atmosphere around our planet. For a long time ecological problems were considered only in the context of biology. But from the mid-20th century the ecological approach invaded all disciplines.
When we study ecology we study the environment and the way plants, animals and humans live together and affect each other. We can say that the environment includes the air, water and land in which people, animals and plants live, but we can also say that it is everything around us. In our everyday life we live in various environments, e.g. in the countryside, in the streets, at home, in the cinema, on a beach, at a swimming pool etc. These different environments may not seem to be connected, but in fact they are.
Ecology is the study of living things in their natural surroundings, or environment. This is everything, living and non-living, that is around them. Its basic features stay very much the same, e.g. the air that you breathe, but the details are constantly changing.
Ecology investigates how plants and animals, including people, live with and affect each other and their environment. A good starting point is yourself. Notice how you affect your own environment. Anything you do to your environment will have an effect back on you, as well as on every other living thing sharing the environment with you. The connections between all living things stretch into a vast web.
If we compare ecology and environment we understand that these words are sometimes used in the same way although they have different meanings. What’s the difference? Ecology is the natural relationship, environment refers to the places or situations. But ‘ecological’ and ‘environmental’ are sometimes used with the same nouns, e.g. an ecological disaster = an environmental disaster. Eco-friendly and environmentally friendly are also used as synonyms for products and methods which do not damage the environment.
People who are concerned about the environment are called eco-warriors (environmental activists). They are often referred to as ‘greens’, e.g. “Greenpeace” and “Friends of the Earth”.

Species loss – 70 species lost every day.
Toxic substances – Can last for decades in animal and human organisms.
Water resources – 1950–2000 amount of irrigated land increase from 20 mln to 60 mln acres. Enormous usage pressure on aquifers, river systems.

1.14 Read the following short texts and answer the following questions. Which text:

● suggests to control energy sources?
● speaks about charity?
● gives the reason of global warming?
● gives information about polluted water?

PRACTICAL ACTION
All the suggested actions on the previous pages must happen worldwide if they are to be successful. This demands much more international cooperation, especially between rich and poor nations. The trouble is that politicians tend to be more concerned with gaining support in their own countries in the short-term, than with the long-term future of the world and its people.
Many people believe that even all these actions will not be enough, and that we must all make very great changes in the way we live. They are working towards this in what is known as the green movement. This used to be called the ecology movement.
At the moment it is mainly charity organizations, that are successfully helping the world’s poor to help themselves.
