Taste

Taste buds or taste receptor cells in the tongue allow a person to taste the different flavors of the food he or she eats. An average person has around 10,000 of these cells, which gets replaced every week or two. As a person gets older, cell replacement is much slower and some of these cells do not get replaced anymore. An older person may then have only about 5,000 working taste buds. 

Heyhonestly, probably not. humans have always had a tendency to waste things. whether it's food, cosmetic, infrastructure, or our abandoned constructions,the landscape is littered with the refuseof man. archaeology wouldn't be a developed discipline if humans didn't leave things behind. in a way it makes us human

hope it mark me as brainlieast.
