Benefits of wetland protection

1. Water resources regulation: Wetlands can absorb and store a large amount of water, and play a role in regulating rainfall and river flow. They can slow down the occurrence of floods and release water to maintain water supply in dry season.

2. Natural filter: Wetlands can filter out pollutants and nutrients in water and purify water quality. Wetlands can filter out many harmful substances, including chemicals, heavy metals, pesticides and fertilizers.

3. Biodiversity conservation: Wetland is the habitat of many rare and endangered species, including birds, fish, amphibians and insects. Wetlands provide abundant food resources and breeding places, and maintain the balance of the ecosystem.

4. Carbon storage and climate regulation: Wetlands have high carbon storage capacity, which can absorb a lot of carbon dioxide and store it in soil and vegetation. By protecting wetlands, we can reduce greenhouse gas emissions and slow down climate change.
