Exercise 4

Ozone depletion is cause for concern because:
A) without atmospheric ozone, greenhouse gases can escape earth's atmosphere, leading to global warming.
B) without ozone, fossil fuels are more likely to react with water vapor in the atmosphere, increasing levels of precipitation throughout the world.
C) without the protection against solar radiation provided by ozone, rates of skin cancer are likely to increase.
D) without ozone, solar radiation can irradiate the Antarctic ice shelf, causing unsafe levels of radioactive isotopes.
E) reduced levels of ozone can increase the rate of respiratory problems in humans, particularly children.
