Ozone depletion slowed, and scientists now project that the ozone holes over the North and South poles will heal themselves over the next few decades.

In a relatively short period during the 1970s and 80s, we discovered the depletion of the world s stratospheric ozone layer, then fixed it.

The Ozone Mafia

Ozone protects us.

Then, when it was discovered that certain chemicals called chlorofluorocarbons (CFCs) were causing the depletion of ozone in the atmosphere, the same groups launched a nasty campaign to discredit that science, too.

The Ozone Layer Winning One for Planet Earth

Consider also the depletion of ocean fisheries through over fishing.

To protect the stratospheric ozone layer, international agreements have been reached to ban the use and trade of the ozone destroying chemicals called chlorofluorocarbons (CFC s).

However, new reports show a thinning of the ozone layer over the Arctic, and last year s Antarctic ozone hole was as large and deep as ever.

Holes in the ozone layer exposed Australians to cancer causing radiation.

We should do more to protect the ozone layer from damage.

Ozone was used during the First World War to disinfect wounds.

However, statistical estimates of its depletion hide much more than they reveal.

The ozone layer helps protect us from ultraviolet radiation from the sun.

Republicans in Congress are pushing for a broader rewrite of the ozone rules.

Unlike its presence at high altitude where ozone acts as Earth's sunscreen from harmful ultraviolet radiation, at low altitudes, ozone is a health hazard contributing to respiratory problems like asthma and bronchitis.

Ozone pollution near Earth's surface is one of the main ingredients of summertime smog.

Yet advanced countries still account for more than 40 of global consumption and resource depletion.

Later, they fought the scientific evidence that sulfur oxides from coal fired power plants were causing acid rain. Then, when it was discovered that certain chemicals called chlorofluorocarbons (CFCs) were causing the depletion of ozone in the atmosphere, the same groups launched a nasty campaign to discredit that science, too.

By 2010, close to 100 ozone depleting substances, including CFCs, will have been phased out globally.

Some features in the conventions for protecting the ozone layer constitute holes of a legal kind.

The Montreal Protocol, which outlawed chlorofluorocarbons and other ozone killing chemicals, was agreed to in 1987.

The increasing population density in rural Africa, with its intensification of farming, is leading to massive soil depletion.

We teamed up underwater photographer Brian Skerry and photojournalist Randy Olson to document the depletion of the world's fisheries.

At issue is an Oct. 1 deadline for states to begin meeting 2015 standards for ground level ozone.

The EPA's website says breathing air containing ozone can reduce lung function and increase respiratory symptoms like asthma.

A few hours after the clouds cleared and the sun came out, and the desert smelled of ozone.

I do not envy future generations for having to address the possible ramifications of global warming and fresh water depletion.

The ozone layer plays an important role in depleting the amount of ultraviolet (UV) radiation that reaches the surface.

Without the decisions taken 20 years ago, atmospheric levels of ozone depleting substances would have increased ten fold by 2050.

Things could have become much worse the ozone destroying properties of halogens have been studied since the mid 1970 s.

What we saw in the destruction of the Bamiyan Buddhas was the depletion of matter, some solid substance falling down and disintegrating.

Twenty years ago, governments adopted the Montreal Protocol, a treaty to protect the Earth s ozone layer from emissions of destructive chemicals.

There are many examples of such action, such as the Montreal Protocol to help reduce the threat to the ozone layer.

The final pitfall is excessively rapid depletion of oil or mineral deposits, in violation of optimal rates of saving, let alone environmental preservation.

Bankwatch's concerns, voiced in 'Rushing into gold can leave people behind, EBRD', are around resource depletion, particularly water, and changes in commodity prices

Rapidly intensifying water scarcity reflects bulging populations, depletion of groundwater, waste and pollution, and the enormous and increasingly dire effects of manmade climate change.

This was especially strange, given that Australia has been one of the big beneficiaries of the Montreal convention, which banned ozone destroying gases.

The phase out of ozone depleting substances through the Montreal Protocol, for instance, shows what can be done when the international community works together.

But this is only part of the story that we celebrate on the International Day for the Preservation of the Ozone Layer (September 16).

With nuclear power regarded as the main technological bulwark against depletion of the world's oil supplies suddenly suspect, oil prices doubled again by the year's end.

Instead, these policies have left hundreds of millions of people even more desperately poor and hungry, and even more vulnerable to drought, pests, and soil depletion.

It is the spectrum of a planet like Earth, showing a presence of nitrogen dioxide, as a clear signal of life, and oxygen and ozone.

Ground level ozone is created when common pollutants emitted by cars, power plants, oil refineries, chemical plants and other sources react in the atmosphere to sunlight.

A legacy of being right on DDT, clean air and water, species and habitat loss, ozone protection, and toxic waste disposal has earned some bragging rights.
