Question

what does the montreal protocol regulate regarding ozone - depleting substances? mining and extraction production and use price and advertising

Explanation:

The Montreal Protocol is an international environmental agreement. Its main goal is to protect the ozone layer. It does this by controlling substances that deplete the ozone. These substances are regulated in terms of their production and use. Mining and extraction are not relevant to ozone - depleting substances in the context of the protocol. Price and advertising are also not the focus of the Montreal Protocol. The key is on production (how much is made) and use (how they are utilized) of ozone - depleting substances.

Answer:

production and use
