What does it mean “to waste” really? When considering everything in existence, all is just recycled through the same systems. Any water going down the drain will eventually evaporate and reform into clouds which will condense, and any food or trash that is thrown out will break down into simple compounds that will be used by living things, such as plants and animals, to make their existence possible. Is there any moral transgression in wasting resources? No. But you should take into consideration whether you would be wasting money you have spent by throwing away things you’ve paid for if you can still use them.
