Recently, the total number of people in the world is still increasing significantly, especially youngsters. This phenomenon leads to youngsters being plentier than the old person in the countries and some say that it benefits us. I strongly agree with the statement and I reckon that it is incredibly true due to the effects it brings, such as a new and fresh mindset from them and the feeling of security that our future is guaranteed by knowing that there will be many pupils who are able to replace the old ones.
