Population growth means increase in the number of people. Rapid population growth puts heavy pressure on natural resources.

Impacts on environment:

• deforestation for housing and agriculture
• overuse of water leading to groundwater depletion
• increased demand for energy causing fossil fuel use and emissions
• higher waste generation and pollution
• loss of biodiversity due to habitat destruction

To reduce pressure:

• promote education and awareness
• family planning and women empowerment
• efficient resource use and sustainable lifestyle

Thus managing population growth is important for environmental protection and sustainable development.
