Stop the Spanish Government from Oil drilling off the coast of Ibiza

The Spanish government has plans to begin drilling for oil in the gulf of Valencia, just a few miles off the coast of Ibiza.
The project is to be financed by Scottish company Cairn Energy, famous for their controversial decision to drill for oil in the environmentally fragile Arctic Circle. The company has been given the go ahead by the government of Madrid.
There is a real danger of a potentially catastrophic oil leak deep beneath the sea and the loud noises from drilling (louder than a plane) could devastate marine life, interfering with ability to orientate, breed and navigate. Eggs and larva are destroyed and internal bleeding, injuries and eventually death, are the result.
The site of the oil rig happens to be the Mediterranean path of marine animals. This could destroy their habitat.
