1. Yes, the amount of UV light that Australians get is a major contributing factor to their high skin cancer rates. Australia has one of the highest levels of UV radiation in the world, and this is linked to the high rates of skin cancer in the country.
2. The high levels of ultraviolet radiation in Australia, combined with the fact that melanin provides less protection against UV radiation than lighter skin tones, contributes to the high skin cancer rates in Australia. Melanin absorbs UV radiation, but it is not as effective at blocking UV radiation as lighter skin tones. This means that people with darker skin tones are more likely to be exposed to higher levels of UV radiation, which increases their risk of developing skin cancer.
