The Costs of Making a DRAM Chip

Anonymous Coward writes "Researchers at the United Nations University in Tokyo studied the physical and environmental costs to produce one 32-megabyte DRAM chip. Their conclusion? The UNU team found that to make every one of the millions manufactured each year requires 32 kg of water, 1.6 kg of fossil fuels, 700 grams of elemental gases (mainly nitrogen), and 72 grams of chemicals (hundreds are used, including lethal arsine gas and corrosive hydrogen fluoride)."

    They should move their operations to the USA where they will be elligible for huge tax breaks.

    Alot of people don't know about these tax breaks: I was going broke paying taxes on my small consultimg firm, when we found about one of the better tax-breaks avaialbe:

    All we had to do was kill a new-born baby harp seal for every hour of billable time, and presto! No taxes for us!

    We get special credit for killing only the cute seals, the deformed ones have less of a tax-break.

    It's good for the environemnt too, because we only want cute seals, we cut the six-pack rings each and every time. We woulden't want one to cause a deformation in one of the seals - there'd go money right down the drain!

    It's a win for us: no taxes
    It's a win for the governemtn: keep the seal hords ay bay
    It's a win for the seals: the get to see fun-time sparkles in the back of their eyes when we bludgon them.
