Final answer:
The weakest argument in the con-globalization article is the claim that globalization could destroy enough of the planet's biological and physical systems that prospects for life itself will be radically compromised. This argument lacks specific evidence and relies on extreme hypothetical scenarios, making it less compelling.
Step-by-step explanation:
The weakest argument in the con-globalization article is the claim that globalization could destroy enough of the planet's biological and physical systems that prospects for life itself will be radically compromised. While it is important to consider the environmental impacts of globalization, this argument is weakened by its lack of specific evidence and reliance on extreme hypothetical scenarios. Without concrete examples or data, this argument fails to provide a convincing critique of globalization.
