GOLD'S HIGH PRICE

Small-scale gold miners, like this man in Thailand, use toxic mercury to extract the gold from dirt. Heating the combined elements with a blowtorch drives off the mercury--polluting the local and global environment--and leaves gold nuggets behind....[More]

OPEN SEWER

This sewer runs right through a dump and into a small town in the African country of Guinea. Residents of this town are among the at least 2.6 billion people worldwide who have no access to sanitation, according to the World Health Organization....[More]

Uncontrolled emissions of smog-forming nitrogen oxides and other pollutants from industry and vehicles leads to pollution clouds over cities, like this haze hovering over Russia's Stalin-era industrial showcase, Magnitogorosk....[More]

GETTING THE LEAD OUT

GETTING THE LEAD OUT

Workers in the developing world, such as this one in Kenya, sort through used lead-acid car batteries, which are then melted down to extract the lead, poisoning the workers, their families and the local environment....[More]

    Eliminate sewage altogether by adopting composting toilets and grey water recycling. The grey water could either be used for irrigation or processed in a similar fashion to how sewage is processed now. Since black water (containing human waste) is no longer in the system, it's much cleaner and easier to process. Basically we can all reduce water use, eliminate water contamination from human excriment, save the city a ton of money on waste water processing, and get free fertilizer. The city can even offer a free compost collection service, then turn around and sell the compost to farmers. Just doing that will eliminate a ton of polution.

    I take it when you quote smog in cities, you include smoke particles in indoor kitchen fires, which are one of the worlds most important pollutants, causing millions of lung conditions?

    In addition, kitchen smoke-related disease can be eliminated by adopting charcoal burners, thereby avoiding what are in reality thousands of millions of sick children and adults.

    regarging the smalter at La Oroya, you failed to mention that the Peruvian govrnemnt owned that plant for 20+ years and literally ran it into the ground. Since Doe Run purchased the plant they have invested hundreds of millions of dollars on the air and water pollution measures. They have installed three water treatment plants where none existed before, and they have installed dozens of air pollution control devices. They are emiting less that 1/3 of what was being elited under the government's control. Additionally they are under increasing pressure from the Peruvian government to do even more. To say there is no oversight is irresponsible and misleading.
