Over the next 20 years, climate change will likely impact the food we eat in several ways. Rising temperatures, changing rainfall patterns, and more extreme weather events could reduce crop yields, affecting the availability of staples like wheat, rice, and maize. Increased CO₂ levels might also lower the nutritional quality of these crops, reducing essential nutrients.

Climate change can expand the range of pests and diseases, leading to higher crop losses and increased costs for managing these issues. Water shortages from altered precipitation and higher evaporation rates may impact irrigation, further affecting food production.

Food prices may rise due to reduced crop yields and higher production costs, making food less affordable, especially for low-income populations. Seafood availability could be affected as changing ocean conditions impact marine ecosystems and fish populations.

Overall, climate change could lead to increased food insecurity by disrupting production and supply chains. Adapting to these challenges will involve developing resilient crops, improving water management, and adopting sustainable farming practices to ensure a stable food supply.
