Answer 1

The correct option is B Human population growth

The most serious of environmental problems facing the world today is overpopulation.

Human population growth is reaching unsustainable levels as it faces a shortage of resources like water, fuel, and food. The population explosion in less developed and developing countries is straining the already scarce resources.

It is a result of an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources.

There are major problems associated with overpopulation: Inadequate fresh water for drinking as well as sewage treatment and effluent discharge. Increased levels of pollution, deforestation, and loss of ecosystems, Changes in atmospheric composition and consequent global warming, etc.

Hence, the correct answer is option B.
