<human>: I'd like to find out about the different types of wetlands.
<bot>: Wetlands are areas that have a high water table and are covered in vegetation, such as marshes, swamps, bogs, and mangroves. They are important because they help to filter pollutants from water before it enters rivers or lakes. There are many different types of wetlands, each with their own unique characteristics. For example, coastal wetlands are found near the ocean and are often dominated by salt-tolerant plants, while freshwater wetlands can be found along rivers and lakes and are typically dominated by aquatic vegetation.
