Nowadays, global warming is one of the biggest problems facing humans. It is the rise in the average temperature of the earth. The main cause of global warming is human activities and its impacts on humans and nature are catastrophic. Therefore, people should find many ways to stop global warming. The essay will discuss global warming, its causes, effects and suggest some solutions for it.

Global warming is mostly man-made. The first cause of the temperature rise is the increase of greenhouse gases emissions from motor vehicles. The burning of fossil fuels from factories also contribute to the emission of harmful gases into the atmosphere. The second cause is the deforestation for farmland, wood and paper. Another reason for global warming is the increasing use of chemical fertilisers on croplands.

Global warming leads to climate change and catastrophic weather patterns such as severe storms, floods, droughts and so on. Thus, people have to suffer from famine, water shortages, heat-related illnesses and infectious diseases. Moreover, the melting of polar ice caps and rising of sea levels make people lose their homes. Another scary effect of global warming is widespread extinction of species since humans cannot exist without species diversity on Earth.

Global warming is seriously affecting our life so everyone of us should do something to reduce it. To begin with, we should use public transport, ride a bicycle or just walk as this helps to reduce a amount of emissions from the burning of petrol in vehicles. Next, we should use renewable energy instead of fossil fuels. Another solution is cutting down use of paper products. This helps to save trees and forests since these products are made from wood.

In conclusion, it is very important to stop global warming for human existence. If we do not prevent global warming, the earth will suffer terrible catastrophes. Consequently, we should take some actions to reduce the risks. I hope we can all understand that it’s everyone's duty to help reduce global warming right now.
