Q

evidence of global warming

A

rising sea levels, melting snow and ice, increased atmospheric temperature, changes in animal and plant behavior

17
Q

ozone depletion

A
  • industrial gases and CFC’s destroy ozone layer
  • ozone layer protects organisms from UV rays
  • ozone depletion not caused BY CO2
  • depletion will increase skin cancer and damage autotrophs
