Option 1 -> The passage mentions energy consumption but doesn't specifically emphasize saving energy "for our future" as the primary concern.
Option 2 -> These activities are mentioned as "ceremonial" actions, but the passage explicitly asks if there's MORE we can do beyond these symbolic gestures.
Option 3 -> Plastic bags are used as just one example of sustainable choices; the passage doesn't advocate for a complete ban nor is this the main focus.
Option 4 -> This captures the core message: the passage begins by highlighting how our energy extraction has increased from 3,000 to 100,000 calories per capita, calls this "abuse of resources," and discusses ways to reduce consumption through sustainable development.
Hence, Option 4 -> The entire passage revolves around the dramatic increase in our resource consumption (from 3,000 to 100,000 calories) and explores how to address this "abuse" through sustainable practices and reducing our ecological footprint -> correct
