Until a hundred years ago as humans, we had a simple, uncomplicated biological connect with nature. It was a straightforward

equation: we drew roughly 3, 000 calories each of energy out of the Earth for our food and life's sustenance. Today that number

per capita has grown to 1, 00, 000 calories. We still need only 3, 000 calories each to nourish life itself. All the rest of this energy

is what we extract from the Earth for everything else besides keeping ourselves alive.

How to soften this abuse of resources? What is sustainable development? How can it be started in our homes? Beyond the

ceremonial planting of green and getting people to run marathons of various lengths in support of the environment, is there

more that we can add to the abstract value of "sustainability"? What are the little things we can do in our day-to-day lives, to

reduce the demand for things that people make and market? Of course, we know that it helps to avoid a plastic bag when you

can use a newspaper bag, or a brown bag, or even a jute bag, which you can use for many more years.

However, there's actually quite a bit more than you and I can do, with very little as cost incurred, and with solutions that are very

feasible and within our reach. It is possible to understand our ecological footprint and its disastrous consequences, in terms of

the impact on the environment that we make.

The primary concern of the passage is

Solution

✅ Correct Option: 4

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
