Such a valid point and what an unexpected point of view!
Historically, I believe the introduction of the ginkgo tree has not been found to be threatening to the introduced envrionment on the whole-- otherwise, I doubt it'd be so popular.
But you're absolutely right, this is not the case for all species and we need to be careful about how we move plants and animals across borders. Thank you for sharing this! A good reminder that critical thinking will be necessary to solve the world's most pressing problems.
