A body of water or waterbody (often spelled water body) is any significant accumulation of water, generally on a planet's surface. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. 

In the environmental context, "waterbody" generally refers to any natural or artificial body of water, such as rivers, lakes, oceans, and wetlands. Waterbodies are important for supporting ecosystems, providing drinking water, and supporting various human activities such as fishing, recreation, and transportation. Here are some examples of "waterbody" in the environmental context:

1. Rivers: Rivers are natural waterways that can vary greatly in size and flow rate. They are important for supporting aquatic ecosystems and are often used for irrigation, hydroelectric power, and transportation.

2. Lakes: Lakes are bodies of water that are typically larger and deeper than ponds. They are important for supporting aquatic ecosystems and are often used for recreational activities such as swimming and boating.

3. Oceans: Oceans are vast bodies of saltwater that cover much of the Earth's surface. They are important for supporting marine ecosystems and provide resources such as fish and other seafood.

4. Wetlands: Wetlands are areas where the water table is at or near the surface of the soil, creating a unique ecosystem that supports a wide variety of plants and animals. Wetlands are important for water quality and can help to mitigate flooding.

5. Reservoirs: Reservoirs are artificial bodies of water that are typically created by damming a river or stream. They are often used for water storage, hydroelectric power, and irrigation.

6. Ponds: Ponds are small bodies of water that are typically shallow enough to support plant growth across the entire bottom. They are important for supporting aquatic ecosystems and are often used for recreational activities such as fishing.

In summary, "waterbody" in the environmental context refers to any natural or artificial body of water, including rivers, lakes, oceans, wetlands, reservoirs, and ponds. These waterbodies are important for supporting ecosystems, providing resources, and supporting human activities. Protecting and managing waterbodies is important for promoting environmental sustainability and human well-being.
