The natural pollution and the anthropogenic pollution
- 1. the Anthropogenic pollution and the Natural pollution USAMVB Timisoara Faculty of veterinary medicine Hygiene department presented by Tannous Jameel
- 2. Pollution is the introduction of contaminants into the natural environment that cause adverse change.
- 3. Pollution can take the form of chemical substances or energy forms (Physical).
- 4. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.
- 5. Major forms of pollution include: Air pollution, light pollution, littering, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, water pollution and etc.
- 6. All living things from one- celled microbes to blue whales depend on Earth’s supply of air and water and soil. When these resources are polluted, all forms of life are threatened.
- 7. Anthropogenic pollution (human-made) : is caused due to human activities. (Burning of fossil fuels, deforestation, mining, sewage, industrial effluent, pesticides, fertilizers, etc.)
- 8. Anthropogenic pollution has always accompanied civilizations , it started from prehistoric times, when man created the first fires. According to a 1983 article in the journal Science, "soot" found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires."
- 9. Metal forging appears to be a key turning point in the creation of significant air pollution levels outside the home.
- 11. Human activities can influence nature , generally on an environment, the change can be overwhelming giving the ravaging effects of present-day climate. Among the major threats of environmental problems that disrupt the natural equilibrium is the reckless discharge of pollutants generated from industrial activities.
- 12. The reason why environmental issues have become such an encircling hazard for the world boils down to people's unawareness of the environmental issues and their irresponsible and cruel attitude towards nature for their own selfish gains.
- 15. Natural pollution A natural pollutant is a pollutant created by substances of natural origin such as volcanic dust, sea salt particles, photochemically formed ozone, and products of forest fibres , among others.
- 17. Volcanic eruptions and forest, swamp and grass fires launch soot and ash into the atmosphere, which reduces sunlight and lowers temperatures. Eruptions and fires also produce carbon dioxide, carbon monoxide and other polluting gases.
- 18. Ozone A chemical formed naturally by the action of sunlight on oxygen, is a pollutant at ground level but beneficial in the upper atmosphere and as a gaseous therapeutic in some treatments in alternative medicine. Ozone shields the Earth from harmful ultraviolet rays from the sun, but it damages plants and causes breathing problems in the lower atmosphere.
- 19. Natural catastrophes can cause immense floods, storms, earthquakes, droughts , forest fires and volcanic eruptions which can also contribute in some types of pollutions or even be initiated by their occurance.
- 20. Ways in which disasters worsen air pollution: - Disasters facilitate release of hazardous material. - Increased release of accumulated pollutants fromvolcaniceruptions and wildfires. - A breeding ground for airborne microbes and mold. - Increased droughts promote sandstorms. - Radon is a radioactive gas that seeps from the ground in some areas.
- 21. Not all natural catastrophes are the work of fate some are man-made. However, the distinction is not always straightforward , particularly in the case of floods, landslidesor wildfires.
- 22. Despite that the pollutants usually get filtered gradually by the main 3 components of the environment which are air , water and soil , the exaggeration of the pollution above the natural limits creates a large damage which can create a cyclical events of different pollutive incidents which are started by the initial pollution cause. Sometimes the natural and the anthropogenic factors can have a combined process of spreading the pollution such as man-made hazards contaminating other regions and soils with the help of sandstorms and floods , or the human-mining releasing nature's dangerous underground gases to the surface of the earth and etc.
- 23. However, the distinction between natural and man-made catastrophes is not always as clear cut as one might think. Some events are wrongly assumed to be natural catastrophes. Either ways we as consciouscreatures must be looking forward and to assist in the preservation of our environment in order to continue thriving and living in a natural and clean world with the human- ecology cooperation and for the survival of life.
