Comprehension

1. Wetlands are among the most productive ecosystems on Earth, providing essential services such as water filtration, flood control, and habitat for a wide variety of species. They act as natural sponges, absorbing excess rainfall and reducing the impact of floods on surrounding areas.

2. Wetlands also play a critical role in improving water quality by filtering pollutants and sediments from water before it enters rivers, lakes, or oceans. Many species of fish, birds, and insects rely on wetlands for food, shelter, and breeding grounds.

3. However, wetlands are disappearing at an alarming rate due to human activities such as agriculture, urbanization, and industrial development. Over the last century, nearly 50% of the world’s wetlands have been lost.

4. Conservation efforts are underway to protect and restore wetlands. These efforts include creating protected areas, enforcing stricter regulations, and promoting sustainable land use practices. Communities are also being educated about the importance of wetlands for their health, economy, and environment.

5. Scientists warn that continued loss of wetlands will not only lead to a decline in biodiversity but also increase the risk of floods, water pollution, and loss of livelihoods for millions of people who depend on these ecosystems.
