Carbon dioxide (CO2)is the gas that causes global warming. Just 1)_ water gets hotter when it is the sun, CO2 causes the Earth's temperature to increase. Almost everything people do, including driving, eating, getting to school or work, and using energy affect how 2)_ C02 is sent into the atmosphere.
Organisations, worried 3)_ the condition of our planet, have come up with a way to measure how much damage we cause when we go about our daily activities. They call 4)_ measurement a 'footprint' and depending 5)_ our behavior, our footprints can be all different sizes. So, let's see what you can do 6)_ have the smallest carbon footprint possible.
7)_ we know that everything we do affects the planet and we can start to make decisions that will make it healthier. 8)_ big your 'footprint' is. You might be quite surprised!
