Question

Which of the following human health effects could result from an increase in ultraviolet radiation?

1) an increase in cataracts cases
2) an increase in skin cancer cases
3) an increase in respiratory diseases
4) an increase in cardiovascular diseases

Answer 1

An increase in ultraviolet radiation can result in an increase in cataract cases and skin cancer cases. Cataracts are clouding in the eye's lens that can lead to vision loss, while UV-B radiation can cause skin cancer by damaging DNA. Treatment for cataracts is available, and prevention measures can help protect against UV radiation.

Step-by-step explanation:

An increase in ultraviolet radiation can lead to several human health effects. One of these effects is an increase in cataract cases. Cataracts are clouding of the eye's lens, which can result in a loss of vision. UV-B radiation can also cause an increase in skin cancer cases, including malignant melanoma. UV-B radiation can damage DNA and lead to mutations, increasing the risk of skin cancer. However, it's important to note that treatment for cataracts is available and successful, and prevention, such as wearing sunglasses, can help protect against UV radiation.
