Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [1]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from ...
This group of organisms includes viruses, bacteria, fungi, and protozoans. While these pathogenic organisms can quickly adapt, other marine life is weakened by rapid changes to their environment. In addition, microbes are becoming more abundant due to aquaculture, the farming of aquatic life, and human waste polluting the ocean.
While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
The types of marine pollution can be grouped as pollution from marine debris, plastic pollution, including microplastics, ocean acidification, nutrient pollution, toxins and underwater noise. Plastic pollution in the ocean is a type of marine pollution by plastics , ranging in size from large original material such as bottles and bags, down to ...
[1] [2] Water pollution and general stresses to aquatic life have a major impact on the environment. The main sources of pollution to oceans, rivers, and lakes are human caused events or activities, such as sewage, oil spills, surface runoff, littering, ocean mining, and nuclear waste.
The aquatic ecosystem consists of a chain of organisms which are dependent on each other. When pollution causes harm to one organism only, this process can start a chain reaction and danger the entire aquatic habitat. When the proliferation of newly introduces nutrients evoke plant and algae growth, oxygen levels in the water decrease.
"The waste from tens of millions of intensely-farmed chickens is finding its way directly into the catchment into the River Wye, causing massive algal blooms, destroying all aquatic life and ...
