write four problems caused in increasing population
Answers
Answer:
Causes of population of growth:
(1) In older days many deaths occurred due to diseases. But the development in medical sciences has controlled the diseases and brought about decrease in the death rate.
(2) Development in agriculture, better techniques to grow more and better quality food.
(3) Food available at all the times due to better storage conditions. So people do not die of starvation when food is not available.
(4) Man formed houses so that he is protected from wild animals and environment. He is safe from the elements of nature.
Today the Earth is home to more than 7.8 billion people. By 2100 the population is on track to hit 10.8 billion, according to the United Nations — and that’s assuming steady fertility declines in many countries. Interestingly, if extra progress is made in women’s reproductive self-determination, and fertility falls more than the United Nations assumes is likely, the population in 2100 might be a relatively smaller 7.3 billion.
