Where there are humans, pollution appears, a curse for the earth?


Where there are humans, pollution appears, a curse for the earth?


The human being occupies the planet, conquers and subdues it, uses it for its benefit, but in every action there is a secondary and negative effect that expands as greed grows and the desire to extract even the last resort to satisfy their greed and foolishness The pollution that grows without stopping and is in the most unsuspected places.

In recent decades, humans have thrown millions of tons of plastic waste into the environment. Plastics, derived from petroleum, take thousands of years to decompose; meanwhile, they pollute waters, intoxicate animals and enter the food chain.

In the North Pacific Ocean, there is the Great Pacific Garbage Patch, larger than the state of Texas, with 696,241 km2. There are garbage patches in other oceans, Indian and Atlantic. For the NOAA (National Oceanic and Atmospheric Administration) they are not "garbage islands", homogenous masses, but something dispersed like a galaxy. Actually, if they were islands, it would be enough to lift the dough and remove it. SES scientists calculated that there are 580,000 pieces of plastic per square kilometer in the Atlantic.





The plastic that enters the ocean comes from ships and platforms that are on the high seas (20%); the rest comes from garbage thrown into the sea, collected by the tides on the beach, and garbage thrown intentionally.

Plastics do not biodegrade, they break into small pieces that are consumed by fish and marine mammals. When the polystyrene foam breaks into smaller parts, the components sink into the ocean, thus the pollutant spreads throughout the sea. The direct toxicity of plastics comes from lead, cadmium and mercury. These toxins have been found in many fish and are dangerous for humans. Diethylhexyl phthalate (DEHP) is a toxic carcinogen. Other effects, in addition to the cancers, are revealed in birth defects, immune system errors and problems of child development. Other toxic plastics, BPA or bisphenol-A, used in plastic bottles and food packaging materials interfere with human hormonal function.


The seas are not the only landfills for polluting garbage. The basins of rivers, lakes, cities and surroundings, even outer space are affected. Cities are "natural garbage dumps," but, What happens in places far from cities? No one would think that Everest is a garbage dump as dangerous as garbage dumps in polluted cities and beaches.





Mount Everest, at 8,848 meters above sea level, was the loneliest place on Earth, and perhaps the cleanest; until May 29, 1953, when Edmund Hillary and the guide Tenzing Norgay conquered its summit. Now, this mountain suffers the attacks of a human being without environmental conscience that fills trash and excrement all its slopes.


In May 2018, the Chinese newspaper Global Times reported on an expedition of 30 people who aimed to clean the hill in the middle of the ascent season, with sad results: Only between April and May they collected 8.5 tons of waste (tents, bottles of oxygen, gas cylinders, kilometers of ropes, cans of food and abandoned corpses). Of the total waste collected, 2.3 tons corresponded only to frozen human excrement, which indicates that Everest is a latrine in the heights.

In the base camp (5,350 meters high), the remains are collected and transferred to a low area where they are processed properly; at the furthest bases people dig in the snow to hide feces and urine. According to The Washington Post, by season mountaineers generate 12 tons of human excrement, which are "stored" under the snow. The melting of the mountain takes the excrement to the base camps, putting at risk the health of the climbers who melt the ice to consume it as water. In 2012, the contamination of water sources was already warned; In 2013, a well-known journalist and mountaineer said that the climbers themselves avoided boiling the snow to drink the water for fear of getting an infection. Now, the authorities are looking for real solutions to the problem. The idea is to burn biodegradable waste in the vicinity of Everest and the rest take them to Kathmandu (capital of Nepal) to make souvenirs. A more complex project, the Biogas Project of Monte Everest, aims to create a bioreactor to convert the excrement into compost material; It is expected to work by 2019.




Is space free? No, it is also a less visible landfill, sooner or later the effects will be felt.
