global warming by demi tay

summary :
Greenhouses gases, such as carbon dioxide, trap heat in the atmosphere and regulate our climate. These gases exist naturally, but humans add more carbon dioxide by burning fossil fuels for energy (coal, oil, and natural gas) and by clearing forests. gases act like a blanket. The thicker the blanket, the warmer our planet becomes.Due to deforestation ,many plants trees are being cut down and thus lesser and lesser trees can take in the harmful gases and produce good gases.As the world become more develop there would be more factories that produce harmful gases.

In my opinion, i think that people should reduce using non-biodegradeble stuff such as plastics as it takes a long time to decompose and also release harmful gases that contribute to the global warming.we should also recycle paper and newspaper so as to be more environmental friendly.If every one contribute by doing a small part such as reduce using too much paper it can really make a lot of difference to the environment.
