From time to time a sea current brings death to the Galapagos Islands. El Nino, a meteorological phenomenon which is becoming notorious all over the world, heats up the waters on the Pacific coast and causes terrible death and destruction to animal species. But Galapagos is not dying. The arrival of El Nino is just a part of the ancient cycle of death and rebirth, a reminder of its genesis and a repetition on an infinitely smaller scale of how life colonized these islands and transformed them into an Earthly paradise.

A boiling and burning material from the center of the Earth bubbles up on the surface... iron, sulfur and silicon at over 1,000 degrees centigrade. Something like this must have been the origin of the Galapagos Islands, but with one difference... the birth of the Galapagos Island occurred underwater.

At first glance the landscape could not seem more desolate, a handful of a burnt out islets, almost a 1,000 kilometers away from the nearest coast. It seems impossible that life could reach this land of volcanoes and yet from the very moment that they've appeared on the surface, five million years ago, the Galapagos started to prepare themselves to house life forms. Erosion was probably the first step.

Winds and water currents broke up the volcanic rock in a gradual process in which enough level of soil was formed for seeds to germinate. The wind and the water joined forces in this job. Not that they only eroded the rock to create soil but they also brought real specialists from the continent that accelerated the process. Algae, spit out on the rock, were forming sediments and eventually soil.

All the living creatures that inhabit Galapagos Islands had to cross thousands of kilometers of sea without fresh water and exposed to the equatorial sun to reach these new desert islands.

    I disagree.what you are talking about is a problem for sure.but pesticides are so lethal to the environment and . on the planet its like a nightmare.targeting a power grid in natures balance.pure death to the oceans balance.

    The most unrecognized cause of oceans changing chemistry is neither carbon or industrial pollution but the discharge from urban traffic storm drains at the rate of 2.5 tons for every 200 hectors (about ten square city blocks annually.)

    After a prolonged dry period there is a toxic flush of toxins consisting of phosphate, nitrate, heavy metals etc into the lakes, rivers and oceans.

    Calculate what the volume of discharge from a major city like Los Angles, Peking etc and much will be understood as to the effects of this little studied source of pollution and its effect of the world's waters.

    The lack of understanding this matter is well exampled in the West Coast Canadian city of Victoria, BC where they are spending a billion dollars to treat the city sewage while ignoring or unaware of the principal and far greater source of pollution from storm water drainage coming off the highways and byways of their city streets.

    Recent studies by five universities have demonstrated that juvenile salmon completely lose their ability to identify their natal waters when coming in contact with heavy metals, copper in particular due to the impact on their olfactory sense.

    However, the same scientist were unaware that urban storms coming from city streets were unaware the principal contributor to heavy metal discharges.
