Adam: So this is margarine. It's from Australia, which is close to Singapore. And this is from Denmark so it has to travel a long way to get here.
And here's a picture of me in Sweden. It's my friend's house. It has lots of cows. And in Sweden you can make fresh milk, and cheese and butter.
Shotaro: I'm wondering if you've been to Denmark.
Adam: I don't think so, but I think my mom has.
Ms Leah: How does the margarine get here?
Adam: By ship. If you put it in an airplane, there won't be space. Plus it will cost more money then. And then the margarine will be really expensive.
Pieter: But there are special planes, cargo planes. And they are really, really big.
Adam: But it would be so, so expensive. A boat is cheaper, but from Denmark it has to go a long way through the water.
Siena: That's a lot of food miles.
Pieter: And that means there will be boat pollution. Boat pollution is a gas and it's bad for the Earth.
Johnny: Or a liquid. It can be a liquid too.
Teddy: If there's too much oil, the oil kills the fish and can kill the animals.
We wanted to learn more about this so we watched a YouTube clip about the affect the BP oil spill had on wildlife. The tanker was not transporting food, it was transporting oil, but it shows us what can happen if a lot of oil gets into the water.
