I have been late a few months in mentioning that we are in the year of the Biodiversity. The habitual readership knows that occasionally I speak on biodiversity, and that I have always said that it is a hanging subject in the civil environmental campaign to raise public awareness of the world.
This year that the UNO has declared it of the Biological diversity, the half general practitioners are making diffusion work enough. It suits very much to speak about tigers or lynxes in danger, about the polar bear and the climate change, and the photos can be very spectacular, so the topic sells enough.
To try to show the complexity of the meaning of the biodiversity I am going to mention a pair of examples. A few months ago I commented on the extravagant proposal of a few scientists of reforestar the whole Sahara desert to finish with the climate change. The atrocity of this proposal has many variants, but one of them is to finish with the ecological diversity that supposes a warm desert as the Sahara and therefore with his biodiversity; because a desert is not a dead place.
The interrelations between the living species and the environment are very complex and we cannot control them. For this motive we cannot also control the conservation of certain animal or vegetable species creating artificial preserves or cultivating / breeding in captivity. The proof that the things do not work this way is that the lynxes raised in captivity in Spain suffer from a renal illness that does not observe in the lynxes that they live at large. It is necessary to preserve the natural biodiversity without degrading the environment, without crushing it and later to try to recover it of artificial form, because the most probable thing is that we could not do it.
Finally I leave to you a web of reference that selects a species every day to speak about her in this international year of the biodiversity.
