Yet the fact that our cars are poisoning the air we breathe is like finding that friends are stealing from you. They poison us through the fuel they use. Our car engines really don't work that well, and a lot of waste leaves the exhaust pipe and enters the air. These wastes steal a bit of our health every time we breathe. The worst kinds of waste are carbon monoxide, hydrocarbons, and lead.
Carbon monoxide is the waste that leaves the exhaust in the greatest amounts.
It is a gas that has no taste and no smell. It keeps us from getting enough oxygen from the air. When the brain tells the heart that there isn't enough oxygen, the heart pumps harder. Too much of this overwork can weaken the heart, especially during the course of many years, and possibly lead to heart disease. E. One million 2.
