Climatic change is currently a recurrent topic. The phenomenon is the result of centuries of human activity, mainly the transformation and exploitation of natural resources. Their shortage wasn’t foreseen, and neither was the impact it would cause by unbalancing the environment.
Since the 70’s and as a preamble to the disasters to come, different cities of the world started to experience the atmospheric contamination phenomenon, which lead to some countries warning about the need to reduce the pollution gases freed into the atmosphere, a call very few listened.
In Mexico, the damages of global warming and environmental unbalance have been evident for various decades. The worst natural disasters started to register as earthquakes and climatic events. On the 19th of September 1985, Mexico City lived one of the catastrophes that marked the country’s history, thousands of persons died under the rubble of tens of buildings because of the first earthquake of 8.1 degrees on the Richter scale, and a lower intensity replica the following day.
In 1988, almost three years later, Hurricane Gilberto hit the coasts of the Gulf of Mexico, causing damages mainly in Yucatan. The hurricane devastated more than 50% of the beaches, destroying services and infrastructure.
In 1995 Hurricane Henriette touched land on Cabo San Lucas and Sinaloa, obligating the intervention of the Ministry of National Defense services for helping the victims, and that same year Hurricane Ismael arrived at Topolobampo. During that same year, in October, the country lived an earthquake on the coasts of Guerrero, Oaxaca, Jalisco and Colima. In September 1997, the same areas of Oaxaca and Acapulco felt the force of Hurricane Paulina.
Environmental disasters have been present with more and more intensity in the country; their consequences are becoming more permanent; adding besides, the overflowing of rivers in 1999, in areas of Hidalgo, Veracruz, Tabasco, Puebla, Tlaxcala and Oaxaca.
This 2007, the State of Tabasco lived one of the greatest disasters, not only for the number of victims, but also for the material losses and the resources needed to fix the region. Tabasco is one of the richest states in water resources, with the flow of the rivers Grijalva, Usumacinta, Carrizal and Mazcalapa. The torrential rains surpassed not only the capacity of these rivers, but also of the Peñitas dam, which reached its maximum capacity on the 29th of October, making it necessary to open its floodgates and let out 2 million liters per second, ultimately causing the flood tragedy.
Because of this event and the later worsening of the situation, it was necessary for the army and the civil society to intervene. Boats and helicopters were dedicated to evacuating the zone and safeguarding the thousands of victims.
As if this weren’t’ enough, another tragedy of apparent natural origin affected the neighboring State of Chiapas, in which an avalanche caused an immense wave that buried the town of Juan de Grijalva, causing a blockage of the river with the same name, in which federal authorities and the Federal Electricity Commission worked for reopening the river so it could again flow into the Gulf of Mexico.
