Discussing Cause-2--Revised

Over the past 150 years there has been a huge increase in population and there are some reasons why this situation happens.  First of all, people have advances in medicine and health care; hence, more and more people can be saved from dying and they can receive better care than ever.  Another reason is that people have better sanitation so that there are less infections spreading.  Furthermore, people improved farming methods that produce more and better food; consequently, people could have healthier bodies.  Finally, there are fewer infant deaths and more people living longer; as a result, there are more and more people living in the world.  It’s for all the above-mentioned reasons that find why population increases.
