What we see now a days is not the world how it was 20 years ago and this is because of Global warming.
Global warming can be described as the general increase in temperature of the earth and its oceans, it is believe that this will change the whole world atmosphere and will result in a total climate change. according to scientist the earth temperature is getting higher and higher with a rate of 0.4 'C per year to 0.8 'C per year which is something really to worry about. These Changes results in the form of rising sea levels due to the melting of the polar ice caps, as well as an increase in intensity and severity of climate storms and severe weather change.
some of the most important causes of global warming are :-
Burning Fossil Fuels:-
burning fossil fuels etc in large industries causes a huge amount of smoke containing of highly toxic gases which are disturbing the ozone layer and making a high risk to damage and creating gaps in ozone layer which is very dangerous for all human entities health.
Deforestation:-
another main cause is deforestation. human a destroying forest for their own needs and deforestation is on its peak no a days and no more trees are been planted because of which causes the weather changes, e.g lack of rain, cold weather and warm weather, season duration changes. when the same wood is burnt CO2 is again released which is not friendly to atmosphere. (we need to think about it)
Farming
Animals specially livestock e.g sheep and cattle, produce methane, a greenhouse gas. grazing at a large scale the methane produced is a big contributor to global warming.
Some fertilizers that farmers use also release nitrous oxide, which is another greenhouse gas.
Using different fertilisers and different stock feeds can help to reduce farming's contribution to climate change.
think about it, contribute to save your world not to destroy your world.
