Berners-Lee has even calculated the carbon footprint of cycling to work. Nothing is more environmentally-friendly than riding a bike, surely? Well, it depends on what you’ve had to eat before. To ride a bike we need energy and for energy we need food. So if we eat a banana and then ride a kilometer and a half, our footprint is 65g of CO2. However, if we eat bacon before the bike ride, it’s 200g. In fact, bananas are good in general because they don’t need packaging, they can be transported by boat and they grow in natural sunlight.
So, does this mean that cycling is bad for the environment? Absolutely not, for a start, if you cycle, you don’t use your car, and the fewer cars on the road, the fewer traffic jams. And cars in traffic jams produce three times more CO2 than cars traveling at speed. Cycling also makes you healthy and less likely to go to a hospital. And hospitals have very big carbon footprints!
So maybe it’s time for us all to start making some changes. Pass me a banana and a pint of local beer, please.
1. According to Berners-Lee, which of the following produces the most carbon dioxide?
AA pint of local beer we drink.
B. A pint of imported beer we drink.
C. A banana we eat before a bike ride.
D. The bacon we eat before a bike ride.
2. Why are bananas good in general?
A. They grow naturally.
