Environment hazards

 Human activities play important role on Earth's atmosphere. During burning of fossil fuels  many harmful gases release  Carbon dioxide (CO2), Carbon monoxide (CO), Methane (CH4), Nitrous oxide (N2O) which is dominant green house gases.Human beings physical activities effect on climate change in different ways: Deforestation, Industrialization, agriculture process, Overpopulation, Burning of fossil fuel ( coal , oil , natural gas) , human waste , green house gas, volcanic activities, Livestock farming . 

Industrialization: They are main source of air and water pollution.  Due to industrial emission poisonous and toxic gases are released in air. Different diseases  cause in human and animal body. As a result, the ozone layer of atmosphere effect,cause acid rain(acidic rain is responsible oxidification or control environment or control  decrease in biodiversity)

Agriculture process:  machinery used for agriculture  these machinery consume fossil fuel . Through burning of fossil fuel  smoke are emitted in air. 

Chemical sprays are use on agriculture to kill insect or pesticide. They are good for agriculture But they cause climate change and global warming. 

Deforestation: (cutting down of trees for human or industrial activities).Trees are main source of oxygen and they absorb carbon dioxide from surrounding.The Deforestation effect on climate such as decrease humidity, less rainfall , climate change , global warming, food shortage , soil erosion. 

Overpopulation: ( human population rise in an area so difficult to fulfill the requirements of population)  Due to the rise of population more  carbon emission cause global warming . Overpopulation effect such as Deforestation,   climate change , biodiversity loss . 

Human waste:  The human waste cause  effect on climate change . By human waste the Carbon dioxide emissions , affect ozone layer or global warming . The human waste mostly affect on the human and animal body. 

Global warming: (  global warming is the gradual increase in Earth's temperature) .The human activities cause  Global warming impacts on environment such as green house gases effect, temperature increase of earth , increase of carbon dioxide emissions, floods , storms , drought , tornadoes, biodiversity loss, water shortage.

 Livestock farming : Animals are necessary for control health and they provide food or milk . Animals are cause many environment issues : pollution of air, climate change, global warming, Carbon dioxide emissions, Deforestation to feed livestock , Soil erosion,  damage wildlife habitat. 

Volcanic activities: ( volcano is a crack in a earth crust from which lava blow up). volcanic lava from earth have contain poisonous gases and Ash. Volcano impact on human: Temperature increase, carbon dioxide emissions, destroy crops, release of pressure, earth movement increase , hot spots get up the earth, environment problems,  damage marine life, volcanic lake, change earth rotation. The volcano occurs main cause is carbon dioxide emissions through human activities. 

Burning of fossil fuel: human being burn fossil fuel like coal , oil or gases for cooking process ,  industrial , agriculture, and to run machinery. They main problem is carbon dioxide, methane and nitrous oxide is harmful gases release that effect ozone layer of earth and global warming.
