Ground level ozone and the ozone hole are two different issues. The delayed EPA regulations would be limiting ozone produced. At ground level, ozone has various health hazards. The ozone hole is from ozone depleting substances reaching high altitude in the environment and destroying naturally occurring ozone. That high elevation ozone blocks UV light from the sun, and is protective for those of us who dislike skin cancer it what not.
Well that's a throwback. Not sure I care for this particular reboot of my childhood media.
