What if no ozone

But, it is very important that the world comply with the Montreal Protocol; delays in ending production and use of ozone-depleting substances could cause additional damage to the ozone layer and prolong its recovery. However, this protective layer has started healing itself. In April , a report surfaced suggesting that a massive hole had developed in the ozone layer over the Artic. Scientists attributed this to climate change. In the first step, solar ultraviolet radiation breaks apart one oxygen molecule O2 to produce two oxygen atoms 2 O see Figure Q The gas is lighter than air.

Chemical dangers: Heating may cause violent combustion or explosion. Reacts violently with air, oxygen, halogens and strong oxidants causing fire and explosion hazard. If it should escape from its tank and come in contact with skin it can cause severe frostbite. Yes, hydrogen can be dangerous. Hydrogen is a colorless, odorless, and tasteless gas. Inhaled hydrogen gas H2 has been shown to have significant protective effects on ischemic organs.

Clinical trials abroad have shown promise that treatment of patients suffering from stroke, cardiac arrest, or heart attacks may benefit from inhaling hydrogen gas during the early recovery period. On the one hand, hydrogen is plentiful in sources such as natural gas and water — and unlike fossil fuels, hydrogen is relatively gentle to the environment. Why so? In as much as the sun has gotten a bad reputation, granted that too much of it can cause sunburn and trigger those early signs of aging wrinkles, sunspots, and a sagging skin , it is also true that the essence it gives out, in the form of light and heat are crucial to our existence and to our health.

It contains high concentration of ozone O3 and is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers 9. Ozone depletion is caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities.

The thinning is most pronounced in the Polar Regions, especially over Antarctica. Scientific studies indicate that the cause of ozone layer depletion is human activity, and specifically, human-made chemicals that contain chlorine or bromine. When these gases get to the stratosphere, they cause depletion of the ozone layer. The greatest ozone depleting substances include;. The production and consumption of all principal halogen source gases by human activities are regulated worldwide under the Montreal Protocol.

Without the Ozone layer in place, radiation from the sun would reach earth directly, damaging the DNA of plants and animals Including humans. Skin cancer rates would be on the rise.

Do sunscreen pills really work? Can we plug the hole in the ozone layer?
