The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air.
And, just to clarify, the kitty litter in your trunk, to be used for traction, needs to be taken out and spread around your tires. Most cars are front wheel drive, so the extra weight alone in the back ain't gonna do you much good.
Clay based cat litter is not the only game in town, and itâs by no means the greenest, either. That eco-distinction actually belongs to far more sustainable alternatives such as recycled shredded newspaper, dried corn, non-food grade wheat hulls, compressed wood sawdust pellets and yes, even sand.
