Environment effects of pollution

 

Pollution has been found to be present widely in the environment. There are a number of effects of this:

·                    Biomagnification describes situations where may pass through trophic levels, becoming exponentially more concentrated in the process.

·                    Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO₂ becomes dissolved.

·                    The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.

·                    Invasive species can out compete native species and reduce biodiversity. Invasive plants can contribute debris and biomolecules that can alter soil and chemical compositions of an environment, often reducing native species competitiveness.

·                    Nitrogen oxides are removed from the air by rain and fertilize land which can change the species composition of ecosystems.

·                    Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.

·                    Soil can become infertile and unsuitable for plants. This will affect other organisms in the food web.

·                    Sulphur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.
