Ultraviolet radiation levels are at record highs
According to a report released by the Canadian Ministry of Environment on April 22, the level of harmful ultraviolet radiation this year is said to be the highest ever, because the earth's protective ozone layer is getting thinner.
The report says ultraviolet radiation shining on the earth increased by 4% this summer and, as a result, exposure to the sun can be more dangerous than ever. The report says cases of skin cancer, sunburn, cataracts and other conditions are increasing corresponding to ultraviolet radiation levels.
Scientists recommend that people avoid the sun between 11pm and 2pm, when the radiation is most intense. At the same time, they advise people to use sunscreen all year round because it prevents ultraviolet rays, wears hats and sunglasses when out in the sun.
Statistics show that the rate of skin cancer has increased from 3-5% per year in recent years.
