Climate change is already making many people hungry all over the world, by disrupting crop yields and pushing up prices. And it is not just food but nutrients that are becoming scarcer as the climate changes. It is the poorest communities that will suffer the worst effects of climate change, including increased hunger and malnutrition as crop production and livelihoods are threatened. On the other hand, poverty is a driver of climate change, as desperate communities resort to unsustainable use of resources to meet current needs.

Correct Option (B)

The passage explicitly describes a reinforcing cycle where climate change exacerbates hunger and malnutrition, particularly among the poor, while poverty itself drives unsustainable resource use, further worsening climate change. This intricate feedback loop necessitates a comprehensive approach that re-evaluates and transforms existing food systems to simultaneously address both poverty-induced hunger and climate resilience.

Incorrect Options:

Option A: While increased funding for poverty alleviation and food subsidies can offer immediate relief, the passage emphasizes a deeper, cyclical relationship between poverty and climate change. This option presents a partial solution rather than a logical corollary addressing the systemic interplay highlighted in the text.

Option C: Although poverty and malnutrition are global concerns, the passage's primary focus is on the specific, bidirectional relationship between poverty and climate change impacts. This option offers a generalized statement about global cooperation against poverty, which, while true, does not capture the precise interaction described in the passage as its most logical corollary.

Option D: Sustainable agricultural practices and food price control are crucial elements in addressing food security. However, the passage presents a broader argument concerning the reinforcing cycle of poverty and climate change, impacting livelihoods and resource use. This option is too narrow, failing to encompass the full scope of the systemic issue discussed.
