Solving Environmental Problems-15
Many now have forgotten that the ozone layer used to be one of the biggest worries back in the eighties.The atmosphere’s ozone levels were dropping fast, and nobody knew why.But since then, the ozone hole has stopped growing, and it is now slowly shrinking.

It seems this coordinated approach has been successful, according to the American space agency, NASA, which has been using satellites to monitor the ozone hole.

In 1979, the hole had an area of 1.1 million square kilometres, and it grew rapidly in the following years, until it reached a maximum of 29.6 million km2 in 2006.

These are some of the findings from the latest annual surveys conducted by Concito, a Danish think-tank specialising in environmental issues.

But based on lessons learnt from decades of struggling with environmental problems, it seems that the countries of the world can accomplish a lot in a short time, when they manage to work together.

The ozone layer is healing slowly, because the gases that break down ozone remain active in the atmosphere for a very long time.

This means the ozone hole will remain in place over Antarctica for years to come, due to the gases that we have already emitted.Already the following year, the countries of the world agreed to stop using the harmful gases.Little by little, the world turned down the emissions, until they finally stopped using CFC-gases in 2010.If the ozone were to disappear completely, it would be disastrous, since this thin layer of gas serves as a natural shield against the sun’s harmful ultraviolet radiation.The ozone layer became so thin in an area over the South Pole that it became known as the ‘ozone hole’, and the size of this area kept growing.Read to find out the best solutions to save nature!Every day you can see thousands of people buying food, clothes, items of furniture or goods to make their life better.The world’s average temperature has already risen by about 0.85 degrees Celsius, and if we stopped all CO2 emissions tomorrow, we would still end up with a global warming of about 1.5 degrees compared to pre-industrial levels.This is due to the gases that we have already emitted.The 2 degree solution requires that we reduce the emissions of the problematic gases by 40-70 percent before 2050, and then continue to reduce emissions further until 2100.Even though Denmark is among the most climate-conscious nations of Europe, less than half of Danes consider the climate when they go to vote, and more than one in five do not believe that humanity can do anything to solve the problem.
