The importance of the ozone layer in sustaining life on earth

Itis responsible for the survival of life on earth. This region is called he "ozone layer". It protects us from the harmful ultraviolet rays of the sun Share to: Nearly half the world's people live in towns and cities.

Why Is the Ozone Layer Important?

Ozone in the Earth's stratosphere is created by ultraviolet light striking ordinary oxygen molecules containing two oxygen atoms O2splitting them into individual oxygen atoms atomic oxygen ; the atomic oxygen then combines with unbroken O2 to create ozone, O3.

After negotiation of an international treaty the Montreal ProtocolCFC production was capped at levels with commitments to long-term reductions. See " What does the ozone layer do.

Up to 10 per cent of coral reefs - among the richest ecosystems - have been destroyed, and one third of the remainder face collapse over the next 10 to 20 years. It acts as a blanket and keeps the atmosphere cool.

For example, fisheries that have fed communities for centuries have been depleted in a few years by huge, sonar-guided ships using nets big enough to swallow a dozen jumbo jets at a time.

Up to 10 per cent of coral reefs - among the richest ecosystems - have been destroyed, and one third of the remainder face collapse over the next 10 to 20 years.

The ozone molecule is unstable although, in the stratosphere, long-lived and when ultraviolet light hits ozone it splits into a molecule of O2 and an individual atom of oxygen, a continuing process called the ozone-oxygen cycle.

Holds in our atmosphere like a skin. Why the ozone layer is important. These natural services are so varied as to be almost infinite. February Learn how and when to remove this template message The thickness of the ozone layer varies worldwide and is generally thinner near the equator and thicker near the poles.

We have moved from hacking down trees with stone tools to literally moving mountains to mine the Earth's resources. While the loss of individual species catches our attention, it is the fragmentation, degradation, and outright loss of forests, wetlands, coral reefs, and other ecosystems that poses the gravest threat to biological diversity.

What is the importance of ozone layer?

For approximately 5 percent of the Earth's surface, around the north and south poles, much larger seasonal declines have been seen, and are described as "ozone holes". UV-B radiation can be harmful to the skin and is the main cause of sunburn ; excessive exposure can also cause cataracts, immune system suppression, and genetic damage, resulting in problems such as skin cancer.

The ozone is important to our health. This question has been answered in other categories Our personal health, and the health of our economy and human society, depends on the continuous supply of various ecological services that would be extremely costly or impossible to replace.

Red line shows surface energy level with 10 percent decrease in ozone Levels of ozone at various altitudes and blocking of different bands of ultraviolet radiation. Bynitrous oxide was the largest ozone-depleting substance ODS emitted through human activities. Our need for pieces of nature we once ignored is often important and unpredictable.

The importance is blocking the suns rays from hittimng earth to earth to much but that is just simple 4 people found this useful What is the importance of ozone layer. It helps us to protect against the harmful UVradiations of the sun.

Beginning January 1,only recycled and stockpiled CFCs were available for use in developed countries like the US. It permits there to be life near the surface of the ocean, and on the surface of land.

It protects us fromUV rays of the sun. While the loss of individual species catches our attention, it is the fragmentation, degradation, and outright loss of forests, wetlands, coral reefs, and other ecosystems that poses the gravest threat to biological diversity.

The reduction in biodiversity also hurts us in other ways. Already, we are spending huge sums in response to flood and storm damage exacerbated by deforestation; such damage is expected to increase due to global warming.

This GALEX image of the Cygnus Loop nebula could not have been taken from the surface of the Earth because the ozone layer blocks the ultra-violet radiation emitted by the nebula. See " What is the ozone layer. Scientists warn that even a one-degree increase in the average global temperature, if it comes rapidly, will push many species over the brink.

From the dawn of agriculture, some 10, years ago, through the Industrial Revolution of the past three centuries, we have reshaped our landscapes on an ever-larger and lasting scale. Would you like to make it the primary and merge this question into it.

What is the ozone layer and why is it important?.

Sustaining Life on Earth

This helpful ozone is found in the stratosphere, which is the atmospheric layer just above where life exists and weather occurs. When that same gaseous ozone is found in our lower layer (called the troposphere), it is considered an air pollutant and is.

How do the Ozone layer protect life one on Earth?

Health and Environmental Effects of Ozone Layer Depletion

The Ozone layer blocks the UV rays from entering the Earth, making earth a safer place for humans and animals as the sun is not as extreme as it would be without the ozone layer. There has been a slight uptick of ozone in the air closest to the Earth’s surface (probably from pollution), and a decrease of ozone in the closest layer of the stratosphere.

Ozone is also found much nearer the ground, in the troposphere, the lowest level of Earth’s atmosphere. Unlike the ozone that occurs naturally in the stratosphere, tropospheric ozone is man-made, an indirect result of air pollution created by automobile exhaust and emissions from factories and power plants.

Earth's atmosphere makes conditions on Earth suitable for living things What are three ways in which the atmosphere is important to life on Earth? 1. contains oxygen and.

Ozone acts like a heat shield, to help keep heat on the Earth. Its effect is fairly weak here, but non-zero. Ozone acts to absorb the UV that other gasses cannot, UV which will rapidly cause skin.
