The Swiss Green Cross Environment Protection Agency and the Blacksmith Institute of America have published their findings and presented the 10 most damaging environmental causes in the world.
1. Manual gold mining
With the simplest medium such as gold ore mixed with mercury, the mixture will be melted, the mercury vaporized, and the remaining gold. As a consequence, people inhale toxic gases, and mercury pollutants, pollutants, the environment, accumulate in plants and animals and spread to the food chain.
2. Water surface pollution
Population increases, water resources are increasingly scarce and heavily polluted. Humans can be poisoned by drinking water or eating contaminated food.
3. Groundwater contamination
In urban areas, the placement of waste or toilets does not work well, so poison and pathogens can enter the groundwater. In addition, discharged oils, detergents, pesticides, agricultural fertilizers also contaminate groundwater.
4. Air pollution due to habitat
More than 50% of the world’s population, mainly in developing countries, uses charcoal, firewood and straw for cooking. This is the cause of 3 million deaths worldwide each year and 4% of cases are sick. Cooking usually takes place in a cramped area, with no exhaust system.
5. Industrial mining
The biggest problem is waste disposal in the form of rock and slurry. This waste may have toxic chemicals that people use to separate the ore from the rock. Waste at mines often has sulfide-metal compounds, which can form acid, which in large amounts can be harmful to the surrounding fields and waterways. Sludge from mines flowing into streams and streams can cause flow congestion which can cause floods.
6. Furnaces and processing of alloys
In the process of producing and processing metals such as copper, nickel, zinc, silver, cobalt, gold and cadmium, the environment is severely affected by wastes such as: hydrofluor, sulfur dioxide and nitrous oxide. As well as heavy metals such as lead, arsenic, chromium, cadmium, nickel, copper and zinc. A large amount of sulfuric acid is used for processing. Hazardous solid waste is also harmful to the environment. People normally breathe in these toxic substances or they enter the food chain.
7. Radioactive waste and waste from the extraction of uranium
Radioactive material is used to produce electricity, used in military and medical fields. It is extremely difficult to treat radioactive waste from the reactors in the form of burners. It is almost impossible to permanently bury this waste. Uranium mining does not produce hazardous radioactive waste but generates a large amount of radioactive waste.
8. Waste water not treated
In many areas, manure and domestic waste water are not treated wastewater but back to the water cycle. Untreated wastewater flows into canals and ponds causing oxygen deficiency, which makes many animals and plants impossible to survive. According to WHO, in 2008, about 2.6 billion people did not have access to sanitary facilities. This is the reason why in cities, water is heavily polluted by human excreta. Every year, about 1.5 million people die in connection with untreated sewage.
9. Air pollution in urban areas
Emissions from motorcycles, cars, power plants, industrial parks contain many toxic compounds and fine dust. These substances, when reacted with sunlight to form new compounds, such as ozone, are near very toxic to the ground.
According to WHO estimates, there are 865,000 fatalities caused by air pollution each year.
10. Reuse the battery
Car batteries have so many lead-acid soaked cartridges that can be recharged for multiple uses. These old batteries are often shipped from rich to poor third world countries for reuse. Removal of these batteries is handmade and not safe, so lead incidents often occur in laborers who come into direct contact with old batteries. In addition, in the long run, it also causes chronic poisoning: lead builds up due to very small volume through the respiratory system and accumulation in the bone.
