Final answer:
The Earth's biodiversity is being depleted by human activities, including habitat loss, overharvesting, and climate change. The correct option is (d).
Step-by-step explanation:
Animal extinction, loss of wetlands, damage to coral reefs, and depleting ice floes are all examples of how Earth's biodiversity is depleting the planet's supply of natural resources.
The core threat to biodiversity on the planet, and therefore a threat to human welfare, is the combination of human population growth and the resources used by that population.
Habitat loss, overharvesting, and the introduction of exotic species are a direct result of human activity. Moreover, anthropogenic (human-caused) climate change is predicted to become increasingly significant and represents a substantial threat to biodiversity.
Human activities have increased levels of carbon dioxide in the Earth's atmosphere, leading to the greenhouse effect and climate change, affecting biodiversity.
The depletion and destruction of habitats for agriculture, urban development, and resource extraction such as deforestation for palm oil plantations contribute to the extinction of numerous species.
Thus, human population growth and unsustainable resource use lead to harmful impacts on biodiversity, emphasizing the need for environmental conservation and sustainable practices to protect the Earth's natural resources and the myriad of species that rely on them.
