The pollution of seas, rivers and lakes has disastrous consequences for the marine life of the Mexican fauna. Plastics and other industrial products are the main pollutants.
Plastic invades the sea
Three out of four fish in the Atlantic Ocean – which includes the Gulf of Mexico – have plastic particles in their bodies, according to a study by the National University of Ireland reported by Cultura Colectiva.
Whales, albatrosses, mussels, lobsters, tuna and even plankton are among the 180 marine species that eat 12.7 million tons of plastics, garbage produced by humans in a year. Why?
According to researcher David Attenborough, it is because plastic objects usually have a similar size to the food that sea animals eat.
The cause of this problem is the enormous production of plastic motivated by our excessive consumption of objects made with this material. 5 billion plastic bags are produced per year; every minute one million plastic bottles are bought; and a year throw 13 million tons of plastic, which generates real plastic islands larger than a country, of which there are two in the Atlantic Ocean, another pair in the Pacific and one in the Indian Ocean, according to Dolores Barrientos Alemán, representative of the UN.
The danger of hydrocarbons
Although plastics are an important part of the pollutants that go to the sea, they are not the only ones. The production and transport of hydrocarbons so well is a source of water pollution. Only on August 6, 2018, Noticieros Televisa reported the death of manatees and fish in the Los Bitzales watershed, in Macuspana, Tabasco.
The fishermen attribute the deaths to waters contaminated by hydrocarbons filtered from wells that have not been maintained in decades. His theory is supported by the fact that several Tabascans living in the region have skin lesions and other health effects due to the use of river waters and lagoons where manatees have died.
According to data presented by environmental authorities, high amounts of lead and cadmium were found.
The British Petroleum case
What happened in Tabasco pales in comparison with the environmental catastrophe caused by the oil spill of British Petroleum in the waters of the Gulf of Mexico in 2010.
The oil spill had devastating consequences for marine life in several ways; not only because of compounds extremely toxic to wildlife, which caused deaths and damage to their reproductive systems, but also, due to the darkening of water by oil, blocked sunlight, which prevented the algae from carrying out the process of photosynthesis.
The death of algae due to lack of photosynthesis had serious consequences in ecosystems that depend on plants. Seagrasses are often very affected; also the coral reefs, since many of the algae live in symbiosis with the corals.
All the cases mentioned above have something in common: human action, how we produce, transport and discard what we consume.
