The best method to reduce the threat of overfishing would be to limit the harvest of particular fish species.   The risk of oil spills could be reduced by increasing the use of  renewable energy sources  , which should help decrease oil consumption .  . If an oil spill does occur, bioremediation could be used to help remove the oil so the ecosystem may more quickly recover.

Explanation:

African penguins, which inhabit the coasts of southern Africa, were classified as an endangered species in 2010. Two significant threats to their survival are ecosystem damage from oil spills and overfishing by humans. Overfishing depletes the food supply of African penguins.

The best method to reduce the threat of overfishing would be to

1. Construct a corridor to connect penguins and fish

2. Limit the harvest of particular fish species

3. perform a population survey on several fish species

 The risk of oil spills could be reduced by increasing the use of

1. Natural resources

2. Renewable energy sources

3. Nonrenewable energy sources

, which should help oil consumption

1. Increase

2. Decrease

. If an oil spill does occur, could be used to help remove the oil so the ecosystem may more quickly recover.

1. Bioremediation

2.reforesation

3. recycling

Overfishing can be prevented by formulating policies to limit the harvest of fishes on the basis of species they belong to.

Opting for renewable energy, such as solar or wind energy, would greatly reduce the dependence on non-renewable energy sources such as fossil fuels. Reduction in oil dependence will in turn reduce the risk of oil spillage into the environment. as well as reduce oil consumption.

Spilled oil can be removed from the ecosystem by relevant bioremediation processes. Bioremediation involves the use of biological species to clean up pollutants (such as spilled oil) from the environment.
