Final answer:
Human population growth and overconsumption, including the excessive use of fossil fuels, have had a negative impact on the Earth. This has led to unsustainable resource use, habitat destruction, and reduced populations of fish species.
Step-by-step explanation:
Human population growth has led to unsustainable resource use, habitat destruction, and unsustainable fishing and hunting of wild animal populations. This overconsumption, coupled with the excessive use of fossil fuels, has had a negative impact on the Earth.
Climate change, for example, is occurring due to the enhanced greenhouse effect caused by human actions and excessive use of fossil fuels. Additionally, the unsustainable fishing and hunting of wild animal populations have resulted in reduced populations of fish species.
