Some people say that we should invest money in ecology projects, while others believe that nature is doing well by itself.
The earth is the only planet that people can live on, but nowadays they seem to be doing everything to make their home unfit for living. Industrialization has brought us into conflict with the natural environment. Our planet is in danger; air, water and land pollution have disastrous consequences which threaten human life on Earth.
I strongly feel that the more money is invested in ecology projects, the better our lives are going to be. People have technologies to make our planet cleaner: we can control pollution, recycle waste materials, protect rare animals and plants and install antipollution equipment. We need more disaster-prevention programs in order to control environmental pollution, fight the destruction of wildlife and preserve woodlands. There should be more newspaper articles, TV-programs and science-popular films about ecological problems. They help people become environment-educated.
However, many people still believe that nature is doing well by itself.
To conclude, ecological problems concern everybody and there are ways to solve them. People must always remember that the earth is our home and it depends on us what it will be like.
Many people think that they can't solve the world's environmental problems on their own and that the government and big companies must care about these problems. However, others say that individuals can do much to help the environment.
Our planet is in danger: air, water and land pollution have disastrous consequences which threaten human life on Earth. Most people are convinced that something must be done to stop pollution, but they don't know if they can help.
In my opinion, much can be done by an average citizen. People have to be smart about such things as driving a car or using electricity. Whenever we drive a car, we are adding greenhouse gases to the atmosphere. To make our planet cleaner and to use less energy we can try carpooling. That is when three people ride together in one car instead of driving three cars to work. We can also use public transport, ride a bike, or walk. People can save electricity by turning off lights, our TV-set and computer. We can use less washing up liquids to keep the water clean. We can also plant trees, collect litter and recycle cans, bottles, plastic bags and newspapers. Besides, we can buy products that don't use much energy.
There is a lot of discussion about the destruction of rain forests. Some people don't care about this problem, while others feel that the rain forest must be preserved.
Nowadays rainforests occupy a relatively small area. One can find them in South America and Indonesia, in Thailand and Sri Lanka. Worryingly, rainforests are disappearing at an alarming rate owing to deforestation, river pollution and soil erosion. Quite a lot of people still don't know what effect the destruction of the rainforest may have on the world climate.
Tropical rainforests are called the "world's largest pharmacy" because a lot of natural medicines have been discovered there. More than half of the world's species of plants and animals are found in rainforests. They also offer a way of life to many people living in and around the forest. What is more, rainforests are the lungs of our planet because they produce a significant amount of the world's oxygen.
To conclude, if people want to be healthy and to live happily on Earth, they must preserve rainforests. I think that governments must work together with environmentalists to fight deforestation and to prevent the disappearance of "the lungs of our planet".
Everybody understands that we should recycle our waste. However, most people continue disposing of it in the usual way.
Recycling is an important issue nowadays. Unfortunately, people have always polluted their surroundings. The development of big industrial cities has led to the concentration of huge amounts of waste into small areas. So the obvious solution of this problem is recycling.
I strongly feel that everybody can help recycle waste by collecting litter and by sorting rubbish into different categories. Paper, glass and plastic can be sold to recycling companies. Recycled waste can be made into new products and it can help save natural resources.
But in spite of all the advantages of recycling, there is still a lot of waste everywhere. Many people don't want to sort their rubbish. Some areas still have plenty of landfill space and no recycling centres. They find it rather expensive to transport materials for recycling to big cities. To my mind, there must be more recycling centres not only in big cities, but in small towns as well.
In general, recycling is good for the environment. What is more, it is an interesting and profitable business.
However, all is not so bad. We have thousands of organizations and even corporations that are trying to popularize alternative energy sources. And their work is noticeable. Electric automobiles are becoming more and more popular. Plants and factories are using modern technologies to reduce emissions. Somebody could say "Hey, you're too optimistic and we all are going to the abyss." But I'm not an optimist, I just see all the improvements last years that are believed to change the situation all over the world.
You and I have only to help in this by promoting new harmless technologies. Maybe they aren't too profitable right now, but someday they will replace old and harmful one.
I believe that our future world will not be a big trash. It will be a pretty place with beautiful nature and complementary synthesis of nature and technology.
