What are the causes of global warming?

The causes of global warming is mainly human activities such as deforestation,industrial processes,burning of litters and car produces carbon dioxide.
Deforestation can cause global warming because the process require cutting down of trees which makes the earth to have more carbon dioxide because there are no plants to take in that carbon dioxide.Too much carbon dioxide can cause the atmosphere to disappear and global warming will occur.Industrial processes can cause global warming because the process will produce greenhouse gases also known as carbon dioxide which can cause global warming.Burning of litters can cause global warming because the process requires fire and fire produces carbon dioxide which can also cause global warming.

What are the effects of global warming?

The effects of global warming is mainly droughts,famine and also water level starts to rise.Droughts is a long period of abnormally low rainfall,epsecially one that adversely affects growing or living conditions and a prolonged shortage.Famine is drastic,wide-reaching food shortage where people experience severe hunger,starvation.Water level rising will allow sea creatures to roam all around the world and they get to eat humans like us so that is quite dangerous.
