Air pollution has reached such devastating proportions that it is now the cause of one in four deaths among children under five, according to the World Health Organisation (WHO).
Chart showing the sources of air pollution
Water pollution affects both terrestrial and aquatic life. Aquatic and terrestrial life all depends on water for survival. For example the oil spill by BP caused a lot of damage to both aquatic and terrestrial life. Such a spill prevents air and sunlight from reaching the organisms that live in the water. Without air and sunlight life will not be able to be sustained and all the organisms die. Such pollution also affects the fish since pollutant may block the gills of fish, preventing them from breathing and thus killing them. Oil is also dangerous if ingested by the organism and may cause death because it is harmful. Fertilizers and other farm chemicals find themselves in rivers and lakes when they are washed up by rains. Such chemicals are dangerous to the living organism in the water. Since they are chemicals when ingested they kill organisms in the water. If the water that is contaminated is ingested by humans and other terrestrial animals it may also be dangerous. Such chemicals in humans may cause various conditions including liver and kidney problems. Other diseases for example cholera and diarrhea are a direct effect of ingesting contaminated water. Such diseases lead to loss of life. Industrial wastes that are dumped into rivers and water bodies are also very dangerous (David 28).
