Harvard and NASA the past few days have been talking about the Death Star Galaxy.

Please listen to this video as well as yesterday's video to learn how to reduce atmospheric carbons or greenhouse gasses.

  • @AusAsia Your chemistry may be right but it seems your earth science is off. You make it sound like the Ozone layer is part of the atmosphere that lies beneath the stratosphere. This isn't the case. the "ozone layer" isn't a separate layer of the atmosphere. Ozone is O3 a molecule that generally exists in the Stratosphere since conditions there are most suitable for O3. So your assertion that chlorine descends to the Ozone layer from the Stratosphere seems a bit off to me.

  • @luckyhubbie got 'sunblock'?

  • Well, let's stick to the laws of chemistry and not make up pretend science. Free radicals such as chlorine, DO exceed the altitude of the ozone layer. It's the stratosphere in which they stay for years until they reach the freezing conditions of those "exotic" clouds which the NASA gentleman discussed. The sunlight causes chemical compounds such as chlorofluorocarbon (CFC) to lose a chlorine molecule. Then, the chlorine molecule DESCENDS to ozone layer to convert ozone to oxygen. That's bad.

  • you look like my mom...

  • good thing there is a hole in the Ozone so those pollutants have somewhere to escape our atmosphere.

  • Thank you for wanting to save mother earth.

  • dumb broad

  • carbon is 380 bits per million of the air... carbon just doesnt stay in the air it goes through a process which creates oxygen...

  • good speech miss but i always watch youtube
