Ozone

The Ozone is a molecule,with three oxygen atoms. The Ozone blocks harmful UV rays from hitting us and the Earth. In different layers of the atmosphere the Ozone can be good or bad. In the Troposphere, the Ozone contributes to the smog and greenhouse gas effect. Also it can act as a chemical oxidant, which means it can rip oxygen off you, animals, plants, etc. In the Stratosphere, the Ozone is mostly here. This is where most of the protection is from the UV rays. The Mesosphere, is where there is hardly any Ozone; but the Ozone still protects us from some of the UV rays. Ozone depletion is when the Ozone is being destroyed more than it can produce. Which means the Ozone is disappearing faster than it can produce more Ozone. Also when the CFCs/chlorofluorocarbons, reach the Stratosphere they release chlorine atoms. The chlorine atoms rip off the oxygen atoms from the Ozone, which depletes it.

Greenhouse Gas

Greenhouse gas has a big effect on the world and the environment. The actions we do, effect the greenhouse gases. Whatever we do either helps or makes things worse for the world. Why are greenhouse gases bad? Well they are the cause of global warming, you know the thing that's melting the ice caps and killing polar bears. Yeah, that! Greenhouse gas is made up of water vapor, carbon dioxide, and methane. The atmosphere is trapping those gases, which makes a hole/holes in the Ozone even bigger. And with such a big hole/holes in the Ozone, there's less protection against the harmful UV rays. We the people should be worrying about this crisis, us the children/teens should also worry about this crisis. Because we'll be living with it, and what we do now could either fix it or make it even worse. So please try to help, by saving energy, walking to school, carpooling, and anything else you can think of to help.
