GLOBAL WARNING

Biodiversity loss from Deforestation

Wetlands Destruction Toxic, Carcinogenic, Endocrine, Immune System Disrupting… Nutrient (sewage, fertilizers) Overload

Water Pollution Biodiversity

Nuclear Power

1. COMPARTMENTS AND POLLUTION/EXTRACTION  Air: emissions, ozone loss, abrading, off gassing, noise  Water: chemical emissions, pharmaceuticals, underground leaking, air fallout.  Land: landfill, hazardous and nuclear waste, abrading, soil erosion.  Biosphere (life): habitat destruction, alien specie, exploitation, global warming, pollutants.

2. ENVIRONMENTAL IMPACT OF PETROCHEMICAL INDUSTRY  Air: noxious and toxic emissions from refining, processing plants.  Water: factory emissions to water bodies.  Land: landfill disposal of waste solids & sludge; accidental spills during transport and storage.  Human: toxicity and disruption of lifestyle.

3. ENVIRONMENTAL IMPACT OF METAL INDUSTRY  Air: particulate, gas emissions during forging, working, fabrication  Water: discharge of pickling liquors & other waste disposal; heavy metals  Land: slag, waste products from processing  Human: toxicity

4. ENVIRONMENTAL IMPACT OF MINING INDUSTRY  Air: particulates from surface mining & transportation; noxious and toxic fumes from smelting  Water: runoff from mines and waste disposal  Land: dumping of tailings and processed wastes; disruption of agriculture, forestry, recreation  Human: heavy metals, particulates

5. ENVIRONMENTAL IMPACT OF AGRICULTURE INDUSTRY  Air: drift of agricultural chemicals (pesticides, herbicides, fungicides, fertilizers), pollen, and dust  Water: runoff of agrochemicals to surface waters; percolation to groundwater; silting of water  Land: erosion, depletion of organic material and organisms  Human: toxicity of chemical; loss of soil
