Every year, people pollute the environment with 85 billion tons of waste. Among them are solid and liquid wastes from industrial enterprises and transport, agricultural waste (including pesticides), household garbage and atmospheric precipitation of harmful substances.The main role in soil contamination is played by such components of technogenic waste as heavy metals (lead, mercury, cadmium, arsenic, thallium, bismuth, tin, vanadium, antimony), pesticides and petroleum products. From the soil they penetrate into plants and water, even spring water. Through the chain, toxic metals enter the human body and are not always quickly and completely removed from it. Some of them have the property of accumulating over long years, provoking the development of severe diseases.Global Environmental Issue No. 6: Water PollutionPollution of the world's oceans, underground and surface waters of the land is a global environmental problem, the responsibility for which lies entirely on man.
Winter and summer holidays - are the most favourite and popular among students. Summer holidays are the longest therefore the most long-awaited, and popularity of winter vacation is connected, first of all, with celebration of New Year! This winter holidays began for me in the last school day. We were given the diaries whith final marks, then I took part in Big New Year perfomance as an actor and after the concert we traditionaly had a tea-time in class. Next day was a New Year which I spent in a circle of my big family. Almost right after 0.00 we went for a walk , to arrange salute and to play snowballs. I felt asleep in a second as soon as my head touched a pillow. When I woke up in the morning I found a heap of gifts under the Christmass Tree for me and my cousines. I can't remember a day of this holidays that I have spent playing a computer or watchin TV. I had a lot of fun. I walked with friends and parents. I visited a skating rink, cinema and an exhibition of ice figures, played bowling and even went skiing with the grandfather. The program was so saturated that I didn't notice how time of rest came to an end and I was need to wake up to school.
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. We went to the forest to ski, we made snowmen and played snowballs. We even played hockey! But the winter holidays were over and I returned to the city again. I liked my holidays very much.
