What single-use container uses the least amount of resources from environment

a plastic bottle
a steel bottle
a glass cup
or a paper cup

Paper cup

Explanation:

A paper cup consists of paper and its extracts that are derived from plants and trees. In this regard some people can claim that paper cup uses the maximum resources but this is not the case. Though paper is derived from trees and plants, its overall life cycle cost is very low. Being a natural product its production, decomposition, reduction, re-usage and recycling involves the least cost as compared to a glass, plastic or steel cup or bottle.
