Answer 2

Answer:  

We are advised to use an umbrella in the sun to protect ourselves from the sun’s ultraviolet radiation.  

Explanation:  

The ultra violet radiation reaches the earth’s atmosphere from the sun,  the ozone masks the harmful radiation from the sun but due to continuous environmental exploitation the ozone layer has lost its filtering capacities and therefore the ultraviolet radiation enters the earth’s surface and cause diseases such as skin cancer to the people who get exposed to the radiations.
