The production of apples is a major food industry for humans, making products as fresh apples, applesauce and cider available year-round. The fruit is highly nutritious and parts of the tree have medicinal value as well.

The domesticated apple has escaped into the wild in many areas. These "wild" apples provide an abundant food supply to wildlife, such as deer and birds.

The seeds of apples are highly toxic.

One unfortunate effect of the apple industry has been the widespread use of the chemical compound known as Alar, a ripening agent that can cause cancer and nervous system problems. Its use on U.S. food crops was voluntarily ended by the manufacturer in 1989.
