Recently I've read about a bird called the passenger
pigeon, or wild pigeon,
it lived in North America
a century ago. It was a beautiful, swift and graceful bird.
There were thousands, even millions of them.
I was surprised to find out that today there is not even
one left. All living passenger pigeons disappeared from
the earth entirely. The passenger pigeon became extinct.
It happened for many reasons. The main one is the
change in the pigeons' natural habitat, in the environment.
These birds needed large forests, but farmers needed land,
so they cut down forests. No forests no food for the birds.
Second, many pigeons were shot for sport and because they
were good to eat. At that time, there were no hunting laws
to protect endangered species like there are now. Pigeons
were killed in huge numbers, and there were very few of
them left. There were not enough birds for the species to
survive.
The passenger pigeon is only one of the many plants
and animals that once lived on our planet and have become
extinct. Extinction has been going on since life began on
our planet. But today extinction is happening faster than
ever before.
I feel very concerned about this and wonder what can
be done to stop it?
Good-bye,
