If you don’t know what a pollutant is, its like lets say acid rain its a pollutant and acid rain is bad for plants animals and buildings but a little is normal but a lot is bad. In my class were learning three pollutants they are acid rain, rode salt and fertilizer. rode salt is bad because it is when a car drives on a snow and the snow that got ran over by rubber into the grass and the plant die from the bad snow. we are testing plants to see how they react to pollutant so far its doing good and I hope it will still be good.
