The stock market is creeping back up to one of those high rolling numbers and expert analysts singled out Alcoa among the buzz.

Alcoa is trying to mesh its aluminum manufacturing ways into the world of sustainable building. Could this be a contributor to the buzz? It’s most certainly an indication that something is cooking.

Aluminum has been used for used for years successfully as a building material, known for it’s durability and resistance to decay. At the same time, it’s only ecological relevance seems to be that it is made from bauxite which is found in the earth, and aluminum is recyclable. Recyclable to the umpteenth degree. In other words, where a rose is a rose is a rose, an aluminum can is a door, is a frame, is a gutter, is a siding.

The argument here would of course be how sustainable?  Will Alcoa stop mining bauxite and smelting aluminum, or will they go into the business of recycling, oh let’s see, old cars, and airplanes?

Bauxite is mined from areas with tremendous negative effect on the rain forest, chasing animals out of their habitat, leeching into groundwater, increasing dust clouds, it also takes a tremendous amount of energy to mine and smelt. That, in addition to the fact that once it becomes the building material known as aluminum, it does not decompose. Although some say a can will decompose in 2-five hundred years.

But let’s face it, people get behind a good buzz, so for Alcoa, talks about aluminum products that save energy, and subscribe to LEED standards should prove to be very beneficial. It seems the buzz has arrived before the product, which is a strategic move on the part of Alcoa, using momentum to secure, or add leverage for a positive response from the world of sustainable building.

Alcoa’s big mining project in Brazil is underway, with its ‘responsible’ initiatives in place. They have agreed to put back what they destroy, in an effort to mine sustainably.

Did I really just say “mine sustainably?” Seriously people.

When choosing gold jewelry for your Valentine this year, consider the dirty secrets of this so-called precious metal.

The world’s gold is in short supply and the amount collected in the last 500 yearsd could fill two Olympic sized swimming pools.  Within the last 50 years, the old wild west methods of panning and prospecting have been replaced by mountain leveling, open-pit mining that creates man made earth gashes that can be seen from space.

Having the least vital relevance to human existence, gold generates more waste per ounce than any other metal.  One ounce, the amount found in a typical wedding ring, requires the removal of more than 250 tons of rock and ore.  Cyanide is used to leach gold from the ore and the lead and mercury heavy waste slurry is commonly dumped into local water resources decimating fish, wildlife, and poisoning the food chain for generations.

If you really want to dazzle your Valentine this year, try buy from retailers like Tiffany & Co that are pushing mining standards higher.

Women Gold Miners (Chocó, Colombia)

Chocó is a no man’s land. The large inaccessible rainforest jungle area in the western lowlands of Colombia is mainly inhabited by Afro Colombian population, descendents of African slaves. High presence of malaria, guerilla drug traffic routes, tropical deseases and only an irregular river transport makes this region virtually lost. Gold that is found in the jungle rivers of Chocó is the only hope for many although they never find what they dream about. Women goldminers work in a hot tropical humid climate, miring in the goldbearing mud, searching for the gold and platine dust. They will never give up their effort simply because there is no other way to live off. © www.jansochor.com
