Buses use diesel fuel, one of the worse kinds of fuel you can use. It emits a lot of pollution that is toxic to human health. Diesel cars make people sick. So why use diesel school buses?
School buses travel in places where a lot of children are, so aren't they getting intoxicated with nasty gases like carbon dioxide, carbon monoxide, nitric oxide, nitrogen dioxide, sulfur oxides, and others? And these gases often concentrate inside of buses, making it even worse. Also, studies have shown that longterm inhalation of these gases can lead to lung cancer and other diseases.
So, isn't it best if we replace diesel buses by some other fuel? Like with a hydrogen generator so that it would run on water. Or on trash like in Back to the Future ( no thats just wishful thinking ).
I'm done ranting.
