“Truth will rise above falsehood as oil above water.”
– Miguel de Cervantes
Yesterday, the Spanish Ministry of the Environment decided to concede a positive environmental impact assessment to the oil prospecting promoted by Repsol in the Canary Islands. That’s great. It means, in case they find something, we won’t have to care about petroleum supplying for the next 10 years.
In the meanwhile, seismic prospecting can hurt cetacean’s hearing (their way to find food), kill adult fishes and avoid larvae development. Who cares? Dolphins will be still in the documentaries we fall asleep looking at and both scallops and hakes will be still in Christmas’ meals. If anybody sees a single disadvantage, feel free to comment this post. (Photo: http://www.scienceinseconds.com/blog/beaching-it)
That’s under the water. What would happen in the surface worst case scenario? An oil spill. The Canary Islands hold several UNESCO’s Biosphere Reserves for both marine and island ecosystems. Even at El Hierro I feel like being at home, Lanzarote (especially the northeastern islets) is probably my favorite one. Montaña Clara. What a couple of words. As soon as you land there, you have to care not to walk over the White-faced storm-petrel colony, since you can raze the burrows down. Raise your head! There are several Eleonora’s falcons hunting on lost migrating passerines and the local couple of Osprey, the actual kings of the islet, can fly over you at any time. It gets late and the moon is still hidden. Seabirds start to come in: Bulwer’s petrels, Band-rumped, European and White-faced storm-petrels, thousands of Cory’s shearwaters (don’t forget to look for a Cape Verde, there are already 3 records at this place!) and, in case you are not entranced yet, a sudden male Barolo shearwater makes an appearance. Can you feel it?
Now remove this feeling. Remove it because everything it’s been polluted. Oh, how sad this is… is it? Everybody is enjoying the four miserable drops of petrol they painfully found and only the handful of researchers that used to go to this wonderful islet would missed it as it was. Things that happen either under the water or in the far wild, far from our urban state of prosperity, those are the things people would never actually care about.
Did you even know about the existence of this islet? Did you even know about what species do breed there? How threatened are they? Maybe you signed the popular petition at http://savecanarias.org/ (124100 up to date already did) but did you actually know what were you signing? Please read! The more we know, the less they can lie to us. If you don’t want to, you’d better leave them oil them all.
