Speaker one: Ecology is a branch of science which deals with the world of nature, including humans, at certain levels of biological organization. It is the study of living organisms interacting with each other and with their environment. The focus of ecology is on ecological systems.

Speaker two: Ecology is a multidisciplinary science. Facts about ecological systems are drawn from biology, geology, chemistry, physics and other sciences. Modern ecology has to deal with environmental problems resulting from human activities.

Speaker three: Ecologists also think about the natural balance between plants, animals, people and their environment. If certain species of animals begin to go down in numbers, it usually means that their habitats have been destroyed or are being destroyed. Scientists do research and speak about endangered animals, and in the end, help to save various species.

Speaker four: Ecological problems are becoming more and more serious every year. Pollution is one of them. The environment cannot clean itself because millions and millions of tons of waste get into our lakes, rivers, seas and oceans, and into the soil, and toxic gases get into the atmosphere, poisoning it. There is too much toxic waste in the world. If nothing changes, the planet will die.

Speaker five: Ecologists say that some pollution happens by accident. Chemical factories and nuclear power stations can have accidents, and then you can often do nothing. Everything around these places can become polluted with radiation, and it takes a lot of time to make the area clean and safe again. Unfortunately, some people in different countries destroy the ecology of the planet by polluting it on purpose. They understand how dangerous it is, but still pollute the air, the water and the soil, because it is less expensive to dump toxic waste than buy some modern equipment and safely recycle the waste.

Speaker six: Ecology and the process of global warming are also connected. Nowadays the climate is becoming much warmer in all parts of the world. If the weather gets warmer and warmer, the ice caps in the Arctic, in the North, and in Antarctica, in the South, will melt. The waters of the ocean will rise and many millions of people will lose their homes.
