What on earth has happened? We have lived on Earth thousands of years. It has taken care of us, but have we really taken care of wonderful planet? Look at what we’ve done so far!
Our seas, rivers and lakes We have polluted many of rivers, seas and lakes. We have thrown rubbish from our towns and cities into the oceans. We have also poured chemicals from factories into our beautiful rivers and seas. This has killed millions of fish and other water animals and plants!
Our forests We have cut down thousands and thousands of our plant’s trees, most of them in tropical rainforests. The destruction of the rainforests has killed a large number of animals and plants, and they have disappeared forever. Cutting down the rainforests has also caused flooding in many areas. We’ve got to stop now, before it’s too late!
The air we breathe We have polluted air with chemicals from our cars and factories. This has caused serious health problems for thousands of people all over the world.
We’re Talking Rubbish You’re hungry, so you buy a packet crisps and throw away the packet. No problem, right? Wrong!
Rubbish The disposal of social and environmental problem for thousands of years. The first landfill site in history was opened by the Ancient Greeks about 2500 BC. They realised they had a problem with rubbish in Athens, so they dug a big hole several kilometres outside town, where all the rubbish was thrown.
Landfill Sites The main problem is that we’re producing a huge amount of rubbish each year – millions of tones of it-and the existing landfill sites are nearly full. Where are we going to put all our rubbish in the future?
Animals Ever since true humans appeared on Earth, they have lived in close association with animals. They needed animals for tasks that required strength and speed. People depended on animals for food and clothing, but they also found a source of pleasure and spiritual strength in the animal life.
Trees Trees are amongst the biggest and longest-living things on Earth, some dating back longer than the oldest buildings. Trees are one of the most valuable parts of the environment. People like trees for a lot of reasons. As well as being nice to look at, trees also play an important role in improving the quality of our life.
Pollution People are now more concerned about their environment. One of the most serious environmental problems is pollution in its many forms : air pollution, water pollution, noise pollution and nuclear pollution. As the population of large cities continues to grow, pollution problems become worse.
Environmental Problems Environmental problems have become exceptionally acute in the modern world and environmental protection has become a vital necessity for all people. Our planet is in serious danger. One of the most important environmental problems in the world today is the shortage of clean water.
How to help our planet Today environmental issues are much spoken about on TV, radio and in newspapers. If people want to survive, they must do their best to solve these problems. Fortunately, it’s not too late to save our planet. We understand that our environment is not just our home town but the whole Earth.
Protection of the Environment “Ecology” is a very popular word today. But what does it mean? Ecology is a science which studies the relationship between all forms the Greek “oikos” which means “home”. This 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.
Conclusion We mustn’t forget that planet Earth is our home! We must protect it!
