Answer 1

We will get a lot more UV radiation from the sun, leading to more mutations and cancers. It may dramatically alter life on earth, but it won't destroy it.

How human civilization would fare is a whole 'nother story.

Answer 2

If the ozone layer is sufficiently reduced to cause widespread costs to the consumer, researchers and inventers will create methods for protecting people and property from the effects, and once the side-effects on unowned property start affecting their wallets, the same groups will turn their attention toward protecting the rest of the planet.
You want an efficient way to replenish the ozone from someone whose seen it done? Catalyze the change in the Antarctic ice, creating an ice free zone for settlement and creating ozone and hydrogen for fuel. Biggest danger is the creation of self-reproducing catalysts getting loose, so don't do it.
Not that hydrogen can be used directly as a fuel, but that's another story.

Answer 3

We will have no protection from UV rays, get sick, our ecosystem will quickly deteriorate and everyone will cease to survive due to the lack of being able to grow crops and deal with the unbearable changes in climate/weather conditions...

In other words, we'll be toast.

Answer 4

The deadly UV rays are going to enter the atmosphere which causes skin cancer and many other things. The planet will be distroyed.

Answer 5

It will no longer exist....but you are being overly dramatic. It won't happen in your lifetime (or ever, probably).

Answer 6

We will look like Mars.

Answer 7

it will be toasted baked to a crisp

Answer 8

THE PLANET WILL BE HISTORY
