Environment can be polluted by natural resources or by human activities; this pollution may affect one of the part of environment or all part when those part have an interaction between them. In living part there all organisms including humans but in non living part there are: Water, soil and air as well as temperature and sunlight. Much of the research that is done in the area of environmental science involves interactions. Organisms interact with biotic and abiotic factor in environment An organism may be affected by changes in the environment, and the environment can be affected by organisms. The change that occurred in the environment may have an effect on other organisms The use of chemical fertilizers cause the eutrophication process whereby the use of fertilizers gives the large amount of nitrates and phosphates promote the runaway growth of algae and aquatic plants. In time open-water areas become choked with plant growth. The plants die and decomposed, resulting in a huge increase in the number of recomposed bacteria. This process lowers the amount of oxygen in the water, causing many animals community to die out. My project will be based on how technology of bioremediatio can be used to save our environment .
