Question

easy 10 points on population of 7th class​

Answer 1

Answer:

a population is all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.[1][2] The area of a sexual population is the area where inter-breeding is potentially possible between any pair within the area, and where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas.[3]

In sociology, population refers to a collection of humans. Demography is a social science which entails the statistical study of human populations. Population in simpler terms is the number of people in a city or town, region, country or world; population is usually determined by a process called census (a process of collecting, analyzing, compiling and publishing data).

Answer 2

The world population is increasing at a very fast pace. The last five to six decades have especially seen a tremendous growth in the human population. There are several reasons for the same. One of the main reasons for this is the development in the field of medical science that has brought down the death rate. Another reason is the growing birth rate especially in the poor and developing countries. Lack of education and lack of family planning are among the top reasons for the high birth rate in these countries.

Ironically, while the human population is increasing rapidly, the population of animals and birds is decreasing by the day. In an attempt to satisfy their needs, the humans are cutting down on forests that serve as a shelter for the wild animals. Several species of animals and birds have been impacted due to this. The growing pollution due to the ever increasing traffic and the establishment of various industries is another reason for the decrease in population of the fauna. This is because it is having a negative impact on the weather.

It is time the governments of the countries with high population must take strict measures to control the same else our planet will no longer be fit for the survival of the mankind.
