How pigeons are helping
to fight air pollution?
I know, when
I heard this I thought this was a joke. But it is not. The pigeons have been
flying over the roads so a scientist took the opportunity to monitor the air
pollution. I know what you’re thinking. How? What they do is attach a small
monitor on to the pigeon's back and when it starts fly it will look look at the
smoke produced by cars. Let’s hope it will change something.
