Today, the top environmental challenge is a combination of people and their aspirations. If the aspirations are more like the frugal answer had after the Second World War, a lot more is possible than if we view the planet as a giant shopping mall. We need to get beyond the fascination with glitter and understand that the planet works as a biological system.

Correct Option (C)

The passage explicitly contrasts "frugal aspirations" with viewing the planet as a "giant shopping mall," indicating that excessive consumption and materialistic desires are the primary environmental challenge. It suggests moving "beyond the fascination with glitter" and understanding the planet as a biological system. Therefore, reducing consumerism is presented as a crucial step, aligning with the idea that it is in humanity's self-interest to ensure planetary sustainability.

Incorrect Options:

Option (A): The passage does not assert that the Earth can only meet basic needs. Instead, it critiques the scale of human aspirations and consumerism, implying that current demands exceed sustainable limits, rather than stating an absolute limit to basic provisions.

Option (B): While population can be a factor in environmental challenges, the passage's central argument focuses on the nature of human "aspirations" and consumerist behaviour ("giant shopping mall," "fascination with glitter") as the core problem, not solely the number of people. It emphasizes lifestyle changes over population control.

Option (D): The passage mentions understanding the planet as a "biological system" as important. However, the most crucial inference drawn from the passage's overall emphasis on "aspirations" and the contrast between frugal living and consumerism is the need for a shift in lifestyle and consumption patterns, rather than merely acquiring scientific knowledge. The passage prioritizes behavioural change.
