The destruction of natural habitats is one of the
first causes of the loss of biodiversity. When we transform woods, lands,
jungles… into urban zones, roads, farms… we are destroying hundreds of natural habitats.
And to show that this is real, I’m going to put an
example. Last statistics reveal that 50% of the natural ecosystem was lost in
Mexico last year. As you know, we can
find a lot of woods and jungles there, so, people take advantage of them and
they destroy them in order to build some new buildings, roads, or whatever. But
apart from that, they also kill hundreds of animals. Actually, it seems as if
we don’t realise about the good luck we have, due to the fact that our
statistics are not so high.
Regarding the animals, we can’t forget about not
native species, which are introduced in different places of all around the
world. These type of species can become dangerous for some of the local
species. In Ermua’s dam they introduce some new fish species each year. One of
the most common one is the fish called Blas Blas. These fishes are pretty big,
so they need to eat constantly. In this dam, apart from little fishes there are
also ducks. So what these ugly fiches do, is eating them and leaving that dam without
that duck specie.
