Today I am writing about pollution. Pollution is caused by cars, airplanes, cigarettes etc. You can’t see stars in the sky at night too. Since Covid-19 there are curfews so there is not that many cars which means less pollution. Cigarettes are bad for your lungs and makes pollution. Cars make pollution by the engine that’s what makes pollution same thing with an airplane. So, since an airplanes engine is much bigger than a car’s engine. So, personally I think that airplanes make more pollution just a theory. Factory’s are known for making so much pollution. That’s it. Bye bye!!!!!!!!!!!!
