The video discusses the increase of CO2 in the atmosphere due to greenhouse gas emissions, leading to global warming. It highlights how invasive plant species in Brazil adapt to these changes by growing thinner leaves and stems, which helps them photosynthesize more efficiently. The video is supported by Climeworks, a company that captures CO2 directly from the atmosphere, and encourages viewers to join their climate action efforts.

• Decreased levels of oxygen

How do invasive plants in Brazil benefit from higher CO2 levels?

• By requiring more water

• By growing thinner leaves and stems

• By reducing photosynthesis

• By growing thicker leaves

What adaptation allows invasive plants to use water more efficiently?

• Larger flowers

• Thicker stems

• Thinner leaves

• Deeper roots

What is the primary function of Climeworks as mentioned in the video?

• To plant more trees

• To capture CO2 directly from the atmosphere

• To reduce water usage
