Climate Change And The Effect On Rice

Dr. Lewis Ziska from the USDA is researching the impact of increased atmospheric CO2 on rice growth. Using growth chambers to simulate past, present, and future CO2 levels, Ziska aims to identify rice breeds that thrive in higher CO2 environments. This research is crucial as rice is a staple for 2 billion people. CO2 levels have risen by 30% since the 1960s, and Ziska's work seeks to leverage this increase to boost rice yields, potentially benefiting global food security.

What innovative method does Dr. Lewis Ziska use to study the effects of CO2 on rice plants?

• Climate change time machine

• Genetic modification

• Time travel

• Satellite imaging

Why is it crucial to adapt rice cultivation to higher CO2 levels?

• Rice is a staple food for billions of people.

• Rice is the only crop affected by CO2.

• CO2 levels are expected to decrease.

• Rice cultivation is not affected by climate change.

What is the primary goal of Dr. Ziska's research on rice and CO2?

• To develop new rice flavors

• To increase rice yield by utilizing higher CO2 levels

• To stop rice cultivation

• To reduce CO2 emissions

How much has atmospheric CO2 increased since the 1960s according to Dr. Ziska?

• 20%

• 40%

• 30%

• 10%

What is the potential benefit of developing rice varieties that can utilize additional CO2?

• Decreased global temperatures

• Reduced rice quality

• Higher seed yield

• Increased water usage
