Answer 1

Answer: (D)

All of the above

Hydrocarbons are a class of compounds primarily composed of carbon and hydrogen, and they are major components of oil, natural gas and pesticides. These substances contribute to the greenhouse effect and global warming, deplete the ozone, increase occurrences of cancer and respiratory disorders, reduce the photosynthetic ability of plants and, in the notorious form of oil spills, do untold damage to ecosystems.
