Final answer:
Human impact on tundra and rainforest ecosystems.
Step-by-step explanation:
Humans have impacted both the tundra and the rainforest in various ways. In the tundra, activities such as oil and gas extraction, mining, and infrastructure development have led to habitat destruction and pollution. This can disrupt the delicate balance of the tundra ecosystem and affect the survival of indigenous species. In the rainforest, deforestation for agriculture, logging, and urbanization has significantly reduced the area of pristine rainforest, leading to loss of biodiversity and disruption of ecosystem services. Both ecosystems are important for global climate regulation and provide habitats for unique plant and animal species.
