Are Humans causing global warming
all factories cause smoke and this causes global warming.
cars can cause global warming to because they burn gasses.
Rockets can be cool but they still cause a lot of global warming because once they take off they burn tons of gas
A solution is if humans use their cars less and less then we can save our planet
if humans use bikes then there will be less cars and less cars means no factories which means no global warming!
if we use less of our cars then we can cut down on global warming
if we can do this then the world can be saved
