Final answer:
Extinction is the loss of a species, often accelerated by human activities that reduce habitats and resources. Resource depletion is the unsustainable consumption of natural resources like fossil fuels, contributing to habitat loss and biodiversity decline.
Step-by-step explanation:
Extinction is defined as the irreversible loss of a species from our planet. When human population growth and reckless resource use escalate, we witness a rise in the extinction rates of various species. As humans expand their territories and consume resources, we displace and reduce the habitats essential for the survival of different organisms. For instance, deforestation for agriculture diminishes the living spaces of forest-dwelling species, leading to higher chances of their extinction.
Resource depletion refers to the exhaustion of natural resources due to rapid and unsustainable extraction. Resources such as fossil fuels, fresh water, and wilderness areas are consumed faster than they can be replenished, if at all. This unsustainable exploitation has two key implications: first, it endangers human economies and livelihoods, which depend on these resources; second, it can lead to biodiversity loss by destroying the habitats that species rely on for survival, such as a frog living in the forests of Costa Rica facing threats from deforestation and climate change.
