whte is one thing you can do to change the world ( youssef )

when I look to the wotld . I see more things need to change . But I wsnt to change the pollution . There are two pollutions most important first one air pollution second one water pollution . Every one can not live with out the air . But the people made air pollution by vactories , cars and other things as result there are more people have been goten diseases . fore example, bronchi asthma . Every one have to find about solotion to clear the air . Second one the water pollution . Every one need water for drink and clean , but the human throw the garbage into the ocean or rivers . And the same time all the people use the water . that is big problam to our health .
