Continued depletion of the ozone layer will most likely result in

• an increase in skin cancer among humans 
• a decrease in atmospheric pollutants 
• an increase in marine ecosystem stability 
• a decrease in climatic changes

Deforestation of areas considered to be rich sources of genetic material could limit future agricultural and medical advances due to

• the maintenance of dynamic equilibrium 
• the loss of biodiversity 
• an increase in the ecosystem’s carrying capacity
• the depletion of the ozone layer
