GLOBAL WARMING
What the global warming ?
Global warming refers to a continuous rise in the average temperature of Earth's climate system.
The problem
In 1980’s three british scientists discovered that the ozone layer over Antarctic is getting thinner and the Earth temperature is rising. It is caused by aerosols and detergents containing chemicals.
The effects
Ozone is responsible for main absorption of UV radiation. An overexposure to UV can cause sunburn and skin cancer. It can also make some animals and plants extinct.
The sollution
In late 1980’s the international protocol was signed by many countries to control the emission of chemicals. We can help saving ozone layer by encouraging people to grow plants that produce oxygen.
