The three challenges introduced by population growth and crowding are:
Too much housing
Spread of Diseases
Not enough jobs
<u>EXPLANATION:</u>
Too much housing:
With increased population, the number of houses has also increased because everyone needs s shelter.
Houses are being constructed by cutting down trees thereby harming the environment.
Spread of Diseases:
Spread of diseases is a consequence of population growth and its impact on the environment.
Increased population has led to an increase in the pollution levels which is increasing the spread of diseases.
In this present day, there is 30 percent more chances of people being affected with cancer.
Not enough jobs:
The growing population has led to unemployment.
The number of jobs being created is not increasing in proportion to the population and so, a lot of people are not employed and are unable to earn for their living.
