text: Like how much pollution we were really letting off from our cars. Different settings had different levels of pollution, but it all leads up to be a ridiculous amount. If we limited our car use; we could make a big difference in the amount of greenhouse gases we throw up into our air. Meaning we'll have cleaner air. Can you smell that? Thats the smell of crisp clean air. There's nothing like taking a breath of air out in the wilderness. Where the trees absorbs the contaminated air; only leaving the crisp refreshing air behind. That could be everywhere if we limited car use!
