Health
There is hardly any person who would not like to live a long life staying healthy. For that we  need good health, a precious treasure given us by nature. Of course, some people can inherit bad diseases from their parents but totally there are many opportunities to take care of your own health. Nowadays people have started to realize that good healthis very important, much more important than wealth. To be in good health people must follow a healthylife style, to do things that will help keep a healthy body and mind, to feel fit.But what else must one do to be healthy? It’s necessary to stick to some rules to keep your body and mind in proper shape.
We all like tasty food and we stuff ourselves with all kinds of fat food, hamburgers and chips,pizza and hot dogs. But tasty things are not always healthy.Such food leads to obesity and obesity causes diabetes, heart diseases and other  serious health problems. So to avoid this we should give preferences to home- made meals with a lot offish, lean, vegetables, fruit, dairy products, rough sorts of bread, crops and etc.
Another serious problem of people in modern society is lack of exercise. People are always  in a hurry but still they are not physically active. They stay too long in front of computers and TV-sets. One of the ways to solve this problem is to go in for sports or have physical trainings at least three times a week.Our weak point is bad habits  which are smoking, drinking alcohol, taking drugs. Luckily moreand more people nowadays understand how dangerous these habits can be.Only smoking, for example, kills almost 3 million people each year. The worst thing is that people who live and work with smokers can also suffer from smoke and get  lung cancer as well. A positive sign nowadays is that it`s getting more and more widespreadto ban smoking in public places.
As for me I try to keep to healthy life style. First of all I am very careful about what I take as food and try to avoid products which contain conserving and preserving components which are very dangerous and can causeillnesses and diseases. Spending long hours in front of my computer is my bad habit so from time to time I force myself to give my body some training. I’m not a sporty type of person but I spend a few hours a week at the stadium jogging. As long as I keep to these simple things I feel well and fit.

Natural World in Danger
We have never seen a dodo. The last of these large birds that couldn’t fly died many years ago. Now it is extinct. A lot more endangered species – fish, reptiles, insects, birds and mammals may disappear. The reason is man who kills animals and destroys their habitats.

It is not just animals that are in danger. So are plants. Every day we use paper and cardboard. We use different kinds of wood in furniture and in other ways. Every year over 100000 sq.km. of forests on Earth can be destroyed. This includes rainforests in South America, Africa and Asia. The huge forests help to control the world’s weather and to produce much of the oxygen in the air. There are many illnesses which we still can not cure. It may be that the medicines we need will be discovered in wild plants, in savannas, in deserts or in rainforests.

If we won’t our lives to be healthy and interesting, a lot of other creatures and plants need growing space too.
