all over the history of civilization our nature and its resources is increasingly exploited. when the resources exhaust, the nature becomes "sick". in this situation, it will be all about basic survival, not about the prosperity of mankind. nowadays acid rains, poisoned water and air pollution are the reality we live in.

all around the world there are big cities with thousands of industrial manufactories growing. the result of their work are dangerous substances that poison the air we and our children breathe, the water we drink and the soil on which we grow food.

forests are being cut down rapidly. the large-scale wildfires also contribute to deforestation a lot. unless something is done, people will have nothing to breathe.

water resources are also under the threat. oceans, seas, lakes and rivers are poisoned by industrial and nuclear waste, chemicals, pesticides and herbicides. there will be the day when nothing can live in the sea.

moreover, air is polluted by human activities. plants and factories emit huge amounts of chemicals, which has awful consequences for the environment. for example, acid rain and global warming.

fortunately, the situation is not that bad. if people are aware of that and try to make our world better, then together we can save both the earth and ourselves.

at last the winter holidays came! i was very happy!     i didn't have to get up early in the morning and run to school. i could stay in the bed till midday. but i didn't want to sleep. there were a lot of things to do.

the weather was fine so my freinds and i went to the skating- rink almost every day. it was fun!

then i spent a week in the country where my grandfather and grandmother lived. it was great. i drank milk and eat a lot of tasty food which my granny prepared for me.

i have many friends in this village because i go there every holidays.
