Wetlands play a crucial role in maintaining ecological balance and supporting human activities. They provide essential habitat for various species, assist in controlling flooding by absorbing excess rainwater, and filter pollutants from water sources. Wetlands are found in a range of climates, from warm to cold, and their diverse ecosystems are often threatened by agriculture, development, and invasive species. Understanding the significance of wetlands can help in their conservation and highlight the need for protective measures.
