Correct Option: (a) Our increasing demand for foods sourced from animals puts a greater burden on our natural resources

The passage discusses the future challenges of feeding an increasing global population by 2050. It highlights that the choice of diets in the coming decades will have major environmental consequences. Specifically, it contrasts a diet revolving around meat and dairy, which is rising in the developing world, with a diet based on unrefined grains, nuts, fruits, and vegetables. The author explicitly states that meat and dairy-based diets will 'take a greater toll on the world's resources.' Thus, the core message is that our rising consumption of animal-sourced foods places a significantly heavier burden on natural resources. Option (a) directly and accurately encapsulates this critical message. Option (b) is incorrect because the passage focuses on resource sustainability rather than specific health outcomes. Option (c) is irrelevant to the central theme, and Option (d) contradicts the clear comparison made between the two dietary patterns.
