The easiest way is to buy a device that is made for that purpose.

 Devices made for a specific purpose are often vastly expensive
in comparison with another near equal device made for another
purpose.
 Of course some times they may appear near equal, but maybe
they are not.
 It is often of course also easier to buy something that
is more expensive in comparison with something that is
less expensive.  At least unless you do not have the money
(like taking out a loan).
 I have read that something like a 'Pangea' may have formed
at the end of the Permian, and may have 'separated' some
near the end of the Triassic.  This (might) have produced
some climate change across some of the world's land areas
and this (might) have resulted in some extinctions.

Couple of problems with this scenario. First, the extinction was the most severe ever seen during the Phanerozoic, and "some climate change" hardly seems a big enough cause. Second, the extinction was rapid in terms of geological time, and the formation of Pangaea was a much more gradual thing, which should leave time for populations to adapt.

I am open to the idea that something else may be possible.
