It may indeed, but that doesn't mean it will inevitably become a
problem
here.

Over long time spans, you get more and more species and species
mixtures
evolving that are highly specific to particular locations and habitats
and
which can do this because they are isolated
Then when we come along and mix them with each other you get species
warfare
and you end up with fewer species as one species replaces others either
directly through competition or indirectly through habitat loss/change
(e.g.
Rhodendron ponticum in SW Ireland are replacing Oakwoods and all the
mosses
and liverworts that live in them). That is backwards evolution towards
the
kind of species mix you get in supermarket carparks.

There are only two sides in species warfare. The human species on one
side against which nothing can prevail, and everything else on the other.

Some good points but you completely ignored the point I was making and I can
answer all of the points in the above with these:

In particular I recommend the sections from the GAA and Jackie Healy Rae;
they have comments dotted around their web sites about the effects of aliens
on hurling pitches and roadside dancing in Kerry.
