People don't like poop, but some poop is useful. 3

For example, we can make paper with elephant poop. 4

Then, what can we do with human poop? 5

A special kind of bus runs in England. 6

People call it the “Bio-Bus,” or the “Number Two Bus.” 7

“Number Two” can mean poop in English. 8

The bus gets power from garbage and human waste. 9

It can run about three hundred kilometers. 10

In other words, 11

the bus can travel from Taipei to Tainan 12

with a tank of gas from human waste. 13

Isn't it amazing? 14

Bio-Buses are good for the Earth. 15

Believe it or not, these buses are not stinky at all. 16

Let's all go “Number Two.”
