Final answer:
Replacing Oak trees with Ginkgo trees in an ecosystem could disrupt local wildlife and ecological balance, as Ginkgoes do not establish themselves naturally without human intervention and may not provide the same benefits as native Oaks.
Step-by-step explanation:
The question asks whether Oak trees in an ecosystem should be replaced with Ginkgo trees, which are native to Asia. Replacing native species with non-native ones can have profound effects on the local ecosystem. The Ginkgo biloba is notably resistant to pollution and has been cultivated by humans for thousands of years, particularly around Buddhist temples. It is also known for its ability to thrive in polluted urban environments. However, Ginkgo trees do not naturally establish themselves without human intervention, suggesting that if they were to replace Oak trees, they may not sustain themselves in the long term without continued human cultivation. Additionally, considerations such as the local wildlife that may rely on Oak trees and the ecological balance that Oak trees contribute to would need to be considered before making such a change.
