Pollution

Pollution


There are three types of pollution. Air Pollution, Land Pollution and Sea Pollution.


Air pollution fills the air we breathe with poisonous gasses. The poisonous gasses can kill humans and the air will not be safe to breathe. The poisonous gasses are things that humans can not breathe and if they do not die from it they will get very sick. Acid Rain is the term for pollution when sulfur and nitrogen dioxides combine with atmospheric moisture to produce highly acidic rain, snow,  hail or fog. Pollution from exhaust gases of vehicles is responsible for 60% of all air pollution and in cities up to 80%. There is a large variety of harmful chemicals present in these gases, with lead being one of the most dangerous.
  
Water pollution is the introduction into fresh or ocean waters of chemical, physical, or biological material that degrades the quality of the water and affects the organisms living in it. Mines, especially gold and coal mines, are responsible for large quantities of acid water. Agricultural pesticides, fertilisers and herbicides may wash into rivers and stagnant water bodies. Sewage as well as domestic and farm wastes were often allowed to pollute rivers and dams. Water is discharged from after having been used in production processes. This waste water may contain acids, alkalis, salts, poisons, oils and in some cases harmful bacteria.


Land pollution is the degradation of the Earth’s land surface through misuse of the soil by poor agricultural practices, mineral exploitation, industrial waste dumping and indiscriminate disposal  of urban wastes. It includes visible wastes and litter as well as pollution of the soil itself.


Pollution is not good for planet earth.

Hello,

You have included a lot of information in this report, and a number of interesting words and concepts (like the degradation of the land, and water being discharged). People plant trees near waterways (like we saw on or walk near the stream in Churchill Park) to help stop pollution (from cow manure and fertilisers) going into the waterways.
