Why does population growth put pressure on the environment?

1) The pressure of population growth on land resources. The per capita land in the world is decreasing year by year. Land degradation in developing countries,

Grain output can't keep up with population growth, which makes the world grain supply increasingly tight.

2) The pressure of population growth on forest resources. Excessive population growth will inevitably destroy forests for farmland and houses, which will destroy more and more forest resources.

3) The influence of population on energy. The increase of population makes the energy supply tight and shortens the exhaustion time of fossil fuels.

4) The influence of population on water resources. Population growth is equivalent to the reduction of per capita water resources. At the same time, with the improvement of living standards, the expansion of urban population and the development of economy, the per capita water consumption, domestic water consumption and production water consumption have increased greatly, leading to large-scale water shortage. Population growth has expanded the demand for cultivated land, and "reclaiming farmland around lakes" has seriously damaged surface water resources and greatly reduced the number and area of lakes.

5) The influence of population on mineral resources. With the rapid growth of population, the demand for various mineral resources is increasing, which has caused long-term supply and demand pressure of resource supply and also induced serious environmental problems.

6) The influence of population on climate. Population growth will increase carbon dioxide, nitrogen oxides and sulfur oxides discharged into the atmosphere due to breathing, combustion and industrial development, which may cause acid rain and photochemical smog accidents.
