Describe how the population of the Earth increase if the number of children being born is less?
Ghella [55]

Answer:

As this ratio of land and man was given by demographer Thomas Malthus who said population on grew in an arithmetic and earth production in a geometric fashion.

Explanation:

  • The population or the production capacity of the earth will double and increase as long as it's kept stable i.e no interference from the outside world or human world. Even when there are lower birth and population is still decreasing the earth still will produce less as comparatively due to the slow growth of resources.
  • This population may increase due to the number of medical aid facilities provided or may increase due to the population reaches its maturity and gets fixed or stabilized.
  • Population and growth in resource distribution are always linked to the demographic changes in the population distribution around the world. \
  • As the country of Africa has large scale childbirth and is next after Asia in terms of the population even after several years when its population stabilizes there still going to be pressure on the natural resources as these are finite in numbers.

On the other hand, a person heterozygotes for sickle-cell trait has a selective advantage in environments where malaria is present.
