Answer:
Wetlands are usually defined as the land that is submerged under shallow water, or the soil is saturated with water throughout the year. These inland wetland areas and coastal areas are affected both naturally as well as due to the human activities in different ways such as-
- Due to the increasing rate of water pollution, where the waste particles produced from the industries and factories, and are eventually mixed with the water and polluting it.
- Due to climate change also, these areas are affected.
- Tide also is another factor affecting these areas.
Three of the major harmful impacts of humans on coastal areas are-
- The pollution has increased in the coastal areas as the humans throw the waste materials here and there near to the sea, where these substances are later mixed with the water.
- Due to the setting up of different things such as seawalls, sea-fence, the rate of erosion has considerably increased.
- The marine life also is affected in the coastal areas, because humans often go for fishing in this area.
Three of the major harmful impacts of human on the freshwater ecosystem are-
- The construction of dams directly affects the aquatic species and also degraded the quality of the water.
- Due to the usage of waterways, these marine species are affected.
- A large number of radioactive waste, chemicals, and other waste materials are released from the industrial sectors which are responsible for affecting the freshwater ecosystem.
