In what way can climate change affect food security?

Climate change significantly impacts food security primarily by altering growing seasons and disrupting supply chains. As climate patterns shift due to rising temperatures and changing precipitation patterns, the timelines for planting and harvesting crops can be affected. This can lead to mismatches between when crops are supposed to be grown and when they can actually be cultivated, potentially resulting in lower yields.

Additionally, the disruption of supply chains can occur due to extreme weather events, such as floods and droughts, which can damage infrastructure needed to transport food from farms to consumers. This can create food shortages and increase prices, further jeopardizing food security.

In contrast, the other options do not accurately reflect the realities of climate change. While some regions may experience improved conditions in terms of certain crops, it is not universally beneficial, hence the claim that it increases crop yields for all plants is overly simplistic and incorrect. Similarly, climate change does not eliminate the need for agricultural practices; instead, it may necessitate new methods to adapt to shifting conditions. Lastly, the notion that it creates more favorable weather conditions is misleading, as many areas are likely to experience more extreme weather, which can hinder agriculture rather than support it.
