POLLUTIONS







INTRODUCTION


Pollution is a massive global problem with far-reaching consequences. Air, water, radioactive, and terrestrial pollution affect the lives of millions of people daily, causing disease and death, and contributing to global warming. This book examines how pollution has become a worldwide issue and discusses the debate over possible solutions.



TYPES OF POLLUTION

1. Air Pollution.
Air pollution happen when the air contains gases, dust, fumes or odour in harmful amounts. It may be
dangerous to our health, to animal and plants too.
2. Water Pollution.
Water pollution happen when the river, lakes or seas got contiminated and it will give effect to water creatures, plants and any organism that live in the water
3. Land Pollution.
Land pollution is the contimination of land surface and soil.





CAUSES OF POLLUTIONS

WATER
  • Oil spills make up about 12% of the oil that enters the ocean. The rest come from shipping travel, drains and dumping.
  • An oil spill from a tanker is a severe problem because there is such a huge quantity of oil being spilt into one place.
  • Oil spills cause a very localised problem but can be catastrophic to local marine wildlife such as fish, birds and sea otters.
  • Oil cannot dissolve in water and forms a thick sludge in the water. This suffocates fish, gets caught in the feathers of marine birds stopping them from flying and blocks light from photosynthetic aquatic plants.

AIR

  • Carbon dioxide is one the main pollutants that causes air pollution. This is because, although living beings do exhale carbon dioxide, this gas is harmful when emitted from other sources, which are caused due to human activity.
  • An additional release of carbon dioxide happens due to various such activities. Carbon dioxide gas is used in various industries such as the oil industry and the chemical industry. The manufacturing process of most products would require the use of this gas.
  • There are various human activities that add to the increased proportions of carbon dioxide in the atmosphere. The combustion of fossil fuels and the harmful effects of deforestation have all contributed towards the same. show that amongst the various gasses emitted during a volcanic eruption, carbon dioxide remains to be at least 40% of the emission. Scientists have now therefore identified carbon dioxide as one of those elements that have contributed to global warming.

LAND
  • Solid Waste: Semisolid or solid matter that are created by human or animal activities, and which are disposed because they are hazardous or useless are known as solid waste. Most of the solid wastes, like paper, plastic containers, bottles, cans, and even used cars and electronic goods are not biodegradable, which means they do not get broken down through inorganic or organic processes. Thus, when they accumulate they pose a health threat to people, plus, decaying wastes also attract household pests and result in urban areas becoming unhealthy, dirty, and unsightly places to reside in. Moreover, it also causes damage to terrestrial organisms, while also reducing the uses of the land for other, more useful purposes.


SOIL

  • Soil Pollution: Soil pollution is chiefly caused by chemicals in pesticides, such as poisons that are used to kill agricultural pests like insects and herbicides that are used to get rid of weeds.
  • Hence, soil pollution results from:Unhealthy methods of soil management.
  • Harmful practices of irrigation methods.


EFFECTS OF POLLUTIONS
  • Stingy smell
  • Living things will die
  • Causing many trouble
  • Effects our health .
  • reduced energy levels
  • reduced lung functioning
  • premature death

WAYS TO CURB POLLUTIONS


  • Authoraty the law of polutions
  • Joining prevent polutions campaign
  • Recycling
  • Stop open burning
  • Stop loitering


CONCLUSION



  • Pollution is an undesirable change which affects the physical properties, chemical properties or the biological characteristics of land or water or air. Pollution of natural resources like air, water, and land is due to increased undesirable and uncontrolled human activities.

  • Pollution affects the living organisms and other natural resources on earth. The substance which causes the pollution is called pollutant. The three major types of pollution are the pollution that affects the three major natural resources namely: air, water and soil.
