22. In general, people are living longer now. Discuss the causes of this phenomenon.
People in the world are now living much longer. For example in Europe and North America, the average life expectancy has risen to 68 years for men and 73 years for women. In India life expectancy has been much lower. But improved health and living conditions has now lifted the average life expectancy there to 56 years.
One of the causes that the life expectancy is increasing is the agriculture. Now the agriculture is improved. This means that the people in the world are better fed.
Another cause that people now live much longer is the public health. The public health is improved very much nowadays. There are better living conditions so people live longer because they are protected a bit from diseases.
The last cause is the medicines. The medicines are now better used. There are new medicines in hospitals. So people now have a cure for almost all the diseases. A lot of new chemicals are now discovered. The technology is improved so there are machines that cure diseases.
In conclusion, the people are now living longer for different causes. Some of these causes are: public health, improved agriculture, improved technology, medicines, new chemicals etc. This is a bad thing because there are a lot of natural resources that are being finished and can’t be renewed like coal etc. and the all this because of the population size.
