the ozon layer keeps out harmful uva rays or uvb rays. without the layer, the water would evaporate, and we'd all burn to death. the ozon layer also makes it possible for different gases to stay on earth and not drift off into space. (i.e. oxygen)Why the ozone layer important to living things?
The ozone layer provides form of life for living things. Air to breath, resonable temperature, hydration etc. Basically it is a way to keep these variables constant. As well as fighting global warming..(sheilds from UV rays)
It filters out UV rays. If this light were to hit Earth, most life would die. See the link below to learn about it.
