How many trees would we need to soak up the CO₂ from my school journeys?

Once you've worked it out, that's how many trees we'd need just to cancel out our school journeys. But think about it – we get driven all over the place, not just to school. And here's a mind-bender for you – imagine how many trees we'd need for everyone in Aotearoa. There are more than 5 million of us. That's a whole lot of forests, I reckon. Give it a go and see what number you come up with!
