Good things from Vehicle Emissions

[Sir Mankalot]

What is a possible positive thing that comes from vehicle emissions? I have to do it for a chemistry project and I can't think of one thing. Any ideas? Oh, and by the way its only for High School.

[Spork!!!]

Well, if emmissions include sound energy, then there are some sweet noises to listen too! Is water vapour an emission or is it only emitted @ startup? Heat can also be a positive thing, and plenty of that emitted when an internal combustion engine is running. As the question includes the word possible, your imagination is the limit. You could (possibly) argue that any toxins are in fact helping prevent vegetation from overgrowing the road. Go torment teacher. ;)

The research being taken to reduce emissions leads us to create innovative technological advancements in engine design.

If you were to remove every single car from the road in the UK for a year, it still wouldnt make up for the pollution that Heathrow & Gatwick airport combined produce in a single day

[superspy]

because of emmison crisses the tree huggers now have yet another reason to get together for cheese and crackers and whine about doing nothing....
ie: it brings ppl together socially lmao

I like the idea of tormenting my teacher. He's kind of a perv. Touches everyone. Thank you all for your insight.
