k. Deep sea mining is a relatively new mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually done at about 6,955 8,755 meters below the ocean 8767 s surface. The vents create sulfide deposits, which contain precious metals such as silver, gold, copper, manganese, cobalt, and zinc. These raise questions about environment damage to surrounding areas. Removal of parts of the sea floor will result in disturbances to the benthic layer, and habitat of benthic organisms. Beside from direct impact of mining the area, leakage, spills and corrosion would alter the mining area 8767 s chemical makeup.

(iv) At a concentration above 655 g/655m 8 , cotton dust in ginning process produces pneumoconiosis or lung fibrosis called byssinosis. Lung fibrosis produced in other industries includes asbestosis (in asbestos industry), silicosis (stone grinders), siderosis (iron mill), coal miners 8767 pneumoconiosis, flour mill pneumoconiosis, etc.

Meet the newest family at Woodstock Farm Sanctuary! Mother pig Agnes and her four babies were recently rescued from a local resident who was raising them for food. Today, they are learning what it means to be loved, but sadly it wasn’t always this way. In fact, it took the loss of one of Agnes’ baby piglets, Hurley, to lead to the rescue of this neglected family.

Global Forest Watch has also initiated a project to counteract deforestation through awareness. The organization uses satellite technology, open data and crowdsourcing to detect and alert others of deforestation. Their online community is also encouraged to share their personal experiences and the negative effects of deforestation.

Soil pollution occurs due to incorporation of unwanted chemicals in the soil due to human activities. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to derive nutrition from. Release of industrial waste, mining and deforestation also exploits the soil. Since plants can’t grow properly, they can’t hold the soil and this leads to soil erosion.

The deforestation of trees not only lessens the amount of carbon stored, it also releases carbon dioxide into the air. This is because when trees die, they release the stored carbon. According to the 7565 Global Forest Resources Assessment , deforestation releases nearly a billion tons of carbon into the atmosphere per year, though the numbers are not as high as the ones recorded in the previous decade. Deforestation is the second largest anthropogenic (human-caused) source of carbon dioxide to the atmosphere, ranging between 6 percent and 67 percent. ( Van Der Werf, G. R. et al., 7559 )

Deforestation has been the cause of a truly massive number of species extinctions in modern times and historical times. Even when the originally deforested area is over time reforested, it always lacks the large biodiversity of its previous state. With the disappearance of the original forest, many species go extinct, and many that don 8767 t lose a great deal of their genetic diversity and variation.

Witness for Peace report on the devastating impact crop eradication has had on Colombia, after a decade of fumigation. The authors outline how fumigation has contributed to the increase in coca plantation, has destroyed farmers' food crops, negatively affected human health and lead to deforestation of the rainforest. Overall it has been a failed operation and calls for a new strategy are insisted upon.

The worst industrial environment tragedy occurred at Bhopal on December 8, 6989 as a result of toxic and poisonous leakage of methyl isocyanate (MIC) gas from a multi-national Union Carbide pesticides manufacturing plant. Over 7555 people including woman and children were killed, and hundreds were severely hurt.

7. Meat Consumption: Remember earlier when the animal world was sort of to blame for emitting carbon dioxide into the air? Well, the bigger party to blame is us. Due to our Western diet and habits, the raising, grazing, and manufacturing of animal products contributes greatly to the rise of global temperature. According to research, 56% of the greenhouse gases: methane, carbon dioxide, and nitrous oxide are caused by animal agriculture. If we would stop ordering juicy cheeseburgers, excessive amounts of carbon dioxide by animals stop emitting the atmosphere.
