In this project my partner and I will be tell you about the ozone layer. The ozone layer is disappearing. For those of you who don’t know what the ozone layer is, It’s the layer of atmospheric ozone above the planetary boundary layer. If the ozone layer disappears, temperatures would drastically increase on Earth.

My partner and I chose to do are topic on the ozone layer because not a lot of people care about this issue. Most people don't even know what could happen if the ozone layer disappeared. Like we said in the first paragraph, if the ozone layer disappears the temperatures would drastically increase on the Earth. If we didn't have a ozone layer the temperature would be about 400 degrease every day as an average temperature. The ozone layer allows heat to come in this Earth, without it there would be no filter.

If the Ozone layer disappears every single day it would be about 400 degrees Celsius. For those of you that don't know what “Adverse effects" means changes in the physical environment or biota, including changes in climate, which have significant deleterious effects on human health or on the composition, resilience and productivity of natural and managed ecosystems, or on materials useful to mankind.

The ozone layer exists high in the stratosphere, or a layer of the atmosphere that is roughly 10 to 50 kilometers (6 to 31 miles) above Earth. This buffer around the planet is made up of ozone gas molecules, which consist of three oxygen atoms bound together. Ozone molecules are very spread out. "If you could bring all the ozone molecules overhead together down to the Earth's surface, they would form a layer about 3 millimeters thick. That's only about the thickness of two pennies stacked together.



This thin layer of ozone acts as Earth's natural sunscreen, absorbing the sun's powerful ultraviolet (UV) rays. These invisible energy waves can cause serious damage to living cells. A weakened ozonelayer allows a larger amount of UV light to reach Earth's surface. Not only does that increase the chances of getting sun-burn when you go outside.

The world now knows that danger is shining through the sky. The evidence is overwhelming that the earth's stratospheric ozonelayer, our shield against the sun's hazardous ultraviolet rays. No longer is the threat just to our future; the threat is here and now. Ground zero is not just the South Pole anymore, ozone holes could soon open over heavily populated regions in the northern hemisphere as well as the southern. This unprecedented assault on the planet's life-support system could have horrendous long-term effects on human health, animal life, the plants that support the food chain and just about every other strand that makes up the delicate web of nature. And it is too late to prevent the damage, which will worsen for years to come. media type="custom" key="12151420" Why we need to save the Ozone layer

We need to save the ozone layer because of many different reasons, reason number one as i was saying before If the Ozone layer disappears every single day it would be about 400 degrees Celsius. For those of yo that don't know what “Adverse effects" means changes in the physical environment or biota, including changes in climate, which have significant deleterious effects on human health or on the composition, resilience and productivity of natural and managed ecosystems, or on materials useful to mankind. Reason number two, without the ozone layer there could not and will not be life on this earth. Last reason is that, the earth would be no more the earth would just be like a meterite floating in space.
