What is population explosion? Discuss causes, impact and control strategies of human population growth.

Population explosion refers to a rapid and dramatic increase in the size of the human population over a relatively short period. It occurs when the birth rate significantly exceeds the death rate, leading to exponential population growth. This phenomenon has important implications for resources, environment, social systems, and overall sustainability.

Causes of Population Growth:

1. High Fertility Rates: A major factor contributing to population growth is high fertility rates, particularly in...

Write down the causes of depletion of wildlife in animals?

The depletion of wildlife in animals can be caused by various factors, including:

Habitat loss and fragmentation: Destruction, fragmentation or degradation of natural habitats, such as forests, wetlands, and grasslands, due to human activities like deforestation, agriculture, urbanization, mining, and dam construction, can cause loss of habitat for wildlife and reduce their population.

Climate change: Changes in temperature and rainfall patterns due to climate change can disrupt the natural...

5. Explain Malthus theory of human population growth. 

'Malthus theory" is based on following facts:

1. The means of subsistence (mean of supporting life, like food) grows only arithmetically while unchecked population grows geometrically.

2. The rapid growth of population creates imbalances with the environment.

3. The imbalances at higher degree causes malnutrition, hunger, spread of diseases, droughts, war, etc. which ultimately reduce the population up to the level of the availability of substituent ( food etc).
