how long do you think mankind could last if we keep burning gasoline and our ozone layer?

The ozone layer is recovering. Ozone is also a Greenhouse Gas so it will just add to the Global Warming brought on by man's burning of Fossil Fuels. If we use all Fossil fuels available on the planet, then at some point in the next century Earth will get caught in a "Runaway Greenhouse Effect" similar to what is happening on our sister planet Venus where surface temps are 860F and the atmospheric pressure is 92 times greater than Earth's. That would obviously mean death for every living thing on Earth.

It's real, but your right about there being a natural hole. The size of the hole changes with the season. The cause of the increased size was dealt with in the 1980's with the Montreal Protocol limiting the use of CFCs. It has gotten smaller over the years. It is really more of a history thing now. Ozone close to the ground is a bad thing - hurts peoples lungs if the concentration gets to high and has an effect on global warming (can't remember if it is a greenhouse gas or if it cools off the top of my head). Ozone in the stratosphere blocks some very destructive ultra-violet radiation. Without the ozone layer, life would of had a very hard time moving from the oceans to land because ultra-violet radiation has enough energy to sometimes alter DNA. If you live under the hole (a country in South America did in the 1980s when the hole was largest at the south pole), you can end up with skin cancer. It will kill you if you don't treat it. It was a real problem. There are orbital influences as well as solar cycles that affect the climate and ice age cycles. This also has been long known. Global warming and climate change are affected by the natural cycles but also by human activity. You are just becoming aware of the different ways people change their environment and the potential consequences. All animals change their environment. People just have the unique ability to think ahead and recognize problems that need to be addressed. Back when I was a kid, cancer was the big thing. Everything causes cancer (it may in excess), but one week was hotdogs, the next tap water. It just took a little time to sort out the potential risk and determine if they were really significant. I think that is the link between the ozone hole (a problem identified and solved years ago), global warming (a problem we recognize and are searching for a way to solve), and a "eco-friendly car (a potential solution that may help reduce CO2 emissions partly responsible for global warming). We'll sort the potential risk out and determine a reasonable response at some point. The difference is the cancer problem only required individuals (mostly) to respond, the global warming problem requires major government as well as individual response for all the earth. That is much harder.

Ozone does in fact deflagrate (burn or explode very slowly), if the concentration is high enough (10wt% or higher). This does not happen in Nature, at least not on this planet.

And it is not so much burning gasoline (or any fuel that contains hydrogen), but how much and where.

Why do you think anybody on YA! could answer your question? The question is not "when" (because we can't know), but are we going to hide under rocks until the time comes (because it won't help, there are only so many corpses you could feed on at night).

Look into your neighbor's eyes, and apologize for killing his children's or grandchildren's future, so we can continue to do things in the same old way. For believing the lies long enough that all we can do is save millions and not billions.

But the "haves" don't care, because they will be among the millions... And the really destitute are already pretty much hardended, and able to live on little.

We don't burn the ozone layer. Ozone is non-combustible.

Until we figure out how to turn off the volcanoes, anything we do with gasoline is not going to change anything.

burning has nothing to do with ozone layer - completely different problems

our days are numbered.......
