What types of outdoor activities can be pollution and how can they be affected

Using any type of heavy machinery such as a car or lawn mower can cause pollution. (As for the second part I’m not sure if you’re asking how the world is affected by pollution or how we can prevent pollution, so I will answer both). The world is damaged by pollution in many ways such as the ozone layer thinning out causing global warming, making the water dirty causing animals to die, etc. We can prevent pollution by converting to biofuel.

Pretty sure this would be b. the rest are trick questions. the bystanders  won't go near you if u have cpr cuffs that could hurt them. the dog will back off because the sound will scare him. and the vomits just a stupid trick. if there is that much slober and vomit on the guy hes either choking on it, or just take off his shirt.
