A
How often do you travel by plane?
How much electricity do you u? The days everyone is worried about the size of their carbon footprint. In order to reduce global warming we need to make our carbon footprints smaller. But how much CO2 are we responsible for?
A new book by Mike Berners Lee (a leading expert in carbon footprint) might be able to help. How Bad are Bananas? The Carbon Footprint of Everything looks at the different things we do and buy, and calculates the amount of CO2 all of the following created: the ingredients, the electricity ud in the brewery, the equipment, the travel and commuting of the beer, and the packaging. It’s amazing how many different things need to be included in each calculation. And it’s frightening how much carbon dioxide everything produces.
But all of this can help us decide which beer to drink. From Berners-Lee’s calculations, it’s clear that a pint (568ml) of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer. This is becau the imported beer has been transported from far away, and it us more packaging. The local beer only produces 300g of CO2, but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket.
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 becau 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 y
ou cycle, you don’t u 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, plea.

It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! They can u their n of vision and smell to tell the difference between people who po a threat and tho who do not.

In Kenya, rearchers found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus po a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.
In an experiment conducted by animal scientists, elephants were first prented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all.
Garment color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted
aggressively toward the red clothing.
