Without the Montreal Protocol, more solar radiation would have destroyed plants, lessening the CO2 they absorb One of the most successful environmental treaties in history was finalized 34 years ago to phase out industrial chemicals that eat away at the Earth's delicate ozone layer. The Montreal Protocol introduced an international agreement to phase out chlorofluorocarbons, or CFCs — ozone-depleting chemicals that were once found in refrigerants and other industrial processes. In the decades since, CFCs have plummeted and the infamous “ozone hole” in the Earth’s atmosphere is steadily recovering. Fears of a future in which humans couldn’t safely walk outside in the sun have evaporated. And that’s not all. Studies suggest that global warming could have been even worse than it is today without the Montreal Protocol.
