Which answer is incorrect?

CO2 accumulating in the atmosphere because...

• Humans are releasing CO2 faster than it is captured.

• Plant growth has slowed over time.

• Large amounts fossil fuels are being burned.

• The amount of forest that can capture CO2 is decreasing.

Why is a dead dinosaur relevant to the carbon cycle?

• Human are on the path to extinction like dinosaurs.

• Less people are working in agriculture
• Skirt lengths have changed
• Energy demands have increased dramatically
• The internet allows for faster communication

Photosynthesis by plants and trees is a process…

• that captures carbon from CO2 and converts it into organic matter such as wood and leaves. 
• by which plants absorb O2 during light reactions
• that captures carbon from the atmosphere and converts it into oxygen
• by which plants capture photos from their snapchat feed and convert them to their lock screen.

CO2 is the only significant pollutant influencing climate change.

• the BEST!!
• boring
• really boring
• really really boring

• By plants
• By wind turbines
• By solar panels
• By teachers, and kept until Friday

Your carbon footprint is a calculation that considers all the carbon polluting activities you contribute to. How could you offset the carbon pollution you do create?
