Climate Change and Our Food Supply

The video discusses the impact of climate change on food security, focusing on availability, stability, access, and utilization. It highlights how climate change affects crop yields, water and land resources, temperature, and nutrient density, leading to increased food prices and disease. The video concludes with potential solutions to adapt to these challenges, emphasizing strategic crop choices, improved food handling, and global cooperation.

What are the four key components of food security?

• Availability, Stability, Access, Utilization

• Production, Distribution, Consumption, Waste

• Supply, Demand, Price, Quality

• Growth, Harvest, Storage, Transport

How does climate change affect global yields of wheat and rice?

• Has no impact on these crops

• Doubles the yield of both crops

• Reduces rice yield by 0.3% annually

• Increases wheat yield by 0.9% annually

What is a major consequence of unpredictable precipitation patterns due to climate change?

• Improved soil health

• Decreased food access and stability

• Stable water supply

• Increased crop yields

How does increased heat affect crops like wheat?

• Makes them more heat-tolerant

• Increases their nutrient density

• Has no effect on them

• Decreases their production by 6% per 1°C rise

What is a potential solution to mitigate the impact of climate change on food security?

• Increase reliance on a single crop

• Invest in more efficient irrigation systems

• Ignore soil health

• Reduce food storage facilities

How does climate change influence foodborne illnesses?

• Reduces the need for food safety measures

• Decreases bacterial growth

• Eliminates pathogens

• Increases food poisoning due to warmer temperatures

What is one effect of climate change on food prices?

• Decreases food prices globally

• Increases food prices, limiting access

• Stabilizes food prices

• Has no effect on food prices
