What types of ecosystems are affected by pollution?

As a result of overfertilization, elevated nitrogen inputs also adversely affect a wide range of nitrogen-sensitive ecosystems such as forests, species-rich natural pastures and dry grassland, alpine heathland, raised bogs and fens.

How does pollution affect the forest ecosystem?

Air pollutants also weaken trees, predisposing them to further damage by insects and disease. Some air pollutants can also indirectly impact tree health by altering ecosystem processes such as soil chemistry and nutrient cycling. The result is decreased tree vigor and growth that can culmi- nate in tree death.

Why is air pollution bad for an ecosystem?

They can poison organisms and cause rapid and harmful changes in the environment. These changes may stress certain species, making them more vulnerable to disease and seasonal conditions like drought and cold, and may reduce their ability to respond and survive.

What is the negative effect of pollution?

Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.

In the most egregious cases of air pollution, the health impacts that animals suffer are even visible to the naked eye.

How does pollution affect the deciduous forest?

Air pollutants may impact trees as both wet and dry deposition. … Forests receive higher deposition loads than open fields, depending on the tree species and canopy structure. A higher roughness of the canopy causes higher air turbulences and more intensive interactions between the air and the foliage.
