Greenhouse gases cause global warming
Greenhouse gases pollute the air
Greenhouse gases harms us
Greenhouse gases harm us. When greenhouse gases take away ozone level, we would get more of the sun's rays. Many people get sick from the sun's rays. Air pollution makes our air dirtier and makes it harder for us to breath. When greenhouse gases melt glaciers, rivers and streams would dry up. Farmers could lose their jobs if they didn't have enough water to grow their crops.
