Ecology is the study that helps to preserve the Earth, its plants and animals. It is also supposed to study the environment and the relationship between human activities and nature. Until recently this relationship was in balance. However, at present times we have to face such ecological problems as acid rain, global warming, loss of rare species, ozone reduction, etc. Many scientists think that it is connected with industrial boom and development of civilization in the world. Building numerous factories people have started to interfere intensively in nature. Every year world industry pollutes the atmosphere with tons of dust and other harmful things. As a result many species of animals and plants disappear forever, including fish and birds. Many large cities suffer from factory smog. Their activity pollutes the air, the water, the forests and the land. Apart from factories there are lots of vehicles in the streets of every more or less developed city. It includes cars, motorbikes, buses, minivans, trucks and other types of transport which use fuel. First of all, they exhaust toxic gases into the air. Secondly, they are considered to be the main noise offenders in the city. This problem progresses as the number of cars increases from year to year. As a result the level of harmful substances in the air also increases. Another problem which is worth mentioning is the tree cutting. Trees are a source of oxygen and clean air. So, by doing this people simply violate the biological balance. All the above mentioned ecological problems are the result of man’s careless interaction with nature. In my opinion, environmental protection should become of a global concern and serious measures should be taken to create ecological security.
I do not like winter because:
- Coldly. I do not like the cold.
- To go out, you need to wear a whole mountain of clothes. And she is heavy.
- Without a hat is cold. A hat has a bad effect on hair and hair.
- Winter clothes are expensive. And to walk all winter in one jacket is mortal boredom.
- Ice. You can easily fall and hurt yourself. Or break something.
- On the street in any way without warm clothes. But in stores and pharmacies in it is very hot. Well, even outerwear can be removed, but the shoes are not.
- Short light day and rarely sunny days. And I love the sunshine.
“When you enter a trolley bus or tram, there are heaps of dirty, melting snow and mud puddles from the already melted on the floor.”
- The tracks are sprinkled with sand mixed with salt. It spoils shoes and all this dirt you carry home.
- We do not have adjustment on batteries, so there are two states - hot or cold. And if it's hot, it's still stuffy. And if you open the window, it immediately becomes cold. And all this winter you make this difficult choice.
- Children are constantly sick. Because in winter it is easier to either overcool or overheat.
- It is very difficult to guess with clothes. Especially when it’s sunny and windy at the same time. It turns out that the cheeks are cold, and the back is sweating.
- If you go to the cinema or to the exhibition, you need to look for a place to donate warm clothes. And most often there is a queue.
- Because of the slippery road a lot of accidents.
- If you have a long car ride, it turns out that if it is very cold, you need to get warm to get to the car. And in the car in warm clothes hot. I have to shoot it. And then dress again. And again, the problem of warm shoes.
- If it was snowing at night, by the morning they don’t have time to clear the path and have to wade through the snow.
- The world becomes black and white. There is an acute lack of bright colors.
