Carbon has been our epic issue due to global warming. Carbon levels increased since Industrial Revolution (1800s) where natural sources, especially the combustion of fossil fuels, were used massively for human activites and the process of the industry. These caused ‘greenhouse effect’ where atmosphere traps the outgoing heat from inside and makes heat goes back. This trapped heat then makes temperatures higher and changes the climate.
Today, we still contribute in producing carbon emission by doing some habits we are accustomed with.
