Causes and consequences of Toxic Pollution - Coggle Diagram

- - - - Nutrient pollution is caused by wastewater, sewage, and fertilizers. The high levels of nutrients in these sources end up in bodies of water and promote algae and weed growth, which can make the water undrinkable and depleted oxygen causing aquatic organisms to die.
    - - Land pollution is the destruction of land as a result of human’s activities and the misuse of land resources. This occurs when humans apply chemicals such as pesticides and herbicides to the soil, dispose of waste improperly, and irresponsibly exploit minerals through mining.
        Soil is also polluted through leaking underground septic tanks, sewage systems, the leaching of harmful substances from landfill, and direct discharge of waste water by industrial plants into rivers and oceans.
    - - There are two types of air pollutants, primary and secondary. Primary pollutants are emitted directly from their source, while secondary pollutants are formed when primary pollutants react in the atmosphere.
        The burning of fossil fuels for transportation and electricity produces both primary and secondary pollutants and is one of the biggest sources of air pollution.
    - - Noise is considered an environmental pollutant caused by household sources, social events, commercial and industrial activities, and transportation.
        Light pollution is caused by the prolonged and excessive use of artificial lights at night that can cause health problems in humans and disrupt natural cycles, including wildlife activities. Sources of light pollution include electronic billboards, night sports grounds, street and car lights, city parks, public places, airports, and residential areas.
- - - - The effects of water pollution depend on which chemicals are being dumped where. Bodies of water that are near urbanized areas tend to be heavily polluted by dumbing of garbage and chemicals, both legally and illegally, by industrial plants, health centers, and individuals.
    - - Land and soil pollution has substantial consequences for humans, animals, microorganisms and aquatic life. Contaminated land and soil can cause various problems on the skin, respiratory problems, and even different kinds of cancers.
    - - High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications.
    - - Noise pollution can cause stress, anxiety, headaches, irritability, hearing loss, and sleep loss resulting in decreased productivity. Oil drills, submarines, and other vessels on and in the ocean can cause excessive noise that has resulted in the injury or death of marine animals, especially whales.
