22. In general, people are living longer now. Discuss the causes of this phenomenon. Use specific reasons and details to develop your essay.
We all know that human populations are increasing and scientists can easily prove that. Over the last 300 years there has been a huge increase in human populations. We are going to reveal together the causes of this increase. All these reasons are based on facts that we can also find in scientific books.
One of the most important things is the improved medical care, including control of diseases and improved public health. If those things are improved then lives get better, less people die, more of them are careful, eat better food, go to the doctor, etc. Also there are some drugs that can control diseases inside the body, and there are others which totally destroy diseases. With public health we can have better sanitation and water supplies.
Another reason is the improved agriculture and the increase in amount of buildings and places to live. Improved agriculture means more food, more food means that all people are fed properly and don’t die of starvation. Buildings are needed for people without shelter so they don’t die of the cold outside.
There is also the last but not the least of importance, the war. We know that in wars hundreds and thousands of people die. But now countries can deal with each other about their problems without including war, so less people are dead.
So, these were the things I wanted you to know about the causes the increase of human populations all over the world. These were the reasons of this phenomenon. We hope it will not continue forever or everybody would die of the lack of food, diseases, wars, lack of shelter, etc., etc. Help be part of the solution, not part of the problem - one person can and does make the difference!
