Climate Change and Peanuts

USDA scientists are investigating how climate change and increased CO2 levels affect peanut production. While CO2 can boost plant growth, it may reduce protein concentration in peanuts. Researchers aim to identify peanut varieties that thrive under higher CO2 levels to improve yields. Peanuts are crucial for global diets, especially in developing countries. The study also explores CO2's impact on peanut allergies and carbon sequestration.

What is one potential negative effect of increased CO2 on peanut plants?

• Delayed flowering

• Increased water requirement

• Reduced protein concentration

• Higher pest infestation

What is the main goal of Ziska and his colleagues' research on peanuts?

• To increase the protein content in peanuts

• To develop pest-resistant peanut varieties

• To reduce the water usage in peanut farming

• To identify peanut varieties that yield more with increased CO2

Why are peanuts particularly important in developing countries?

• They are a major source of protein

• They have a high market value

• They require less water than other crops

• They are easy to grow in any climate

What additional aspect of peanuts is being studied by Ziska and his team?

• Their resistance to drought

• Their ability to grow in saline soils

• Their potential in biofuel production

• Their role in carbon sequestration

How might increased CO2 levels affect peanut allergies?

• By making peanuts non-allergenic

• By increasing the allergenic properties

• By having no effect on allergenic properties

• By reducing the allergenic properties
