As I type this rescuers are still trying to save workers trapped for days in the Rana Plaza building in Dhaka, Bangladesh. The BBC report that at least 336 people have died and 600 are missing.
WMD is also a campaigning day to fight for the living as well as remember the dead.
We all have to take responsibility for the dreadful events in Dhaka. The ridiculous cheap prices for clothes at discount stores such as Primark or Matalan is paid for in blood. Shoppers need to understand this and demand responsible and accountable ethical sourcing.
But the problem is wider than this. No doubt the middle class John Lewis brigade will be shaking their heads in disgust at the thought of all these chavs buying their cheap clothes - while at the same time their pension and insurance policies are profiting from the world wide exploitation of the same workers.
Pension trustees need to raise their game and make sure that the companies they invest in have pro active and vigorous supply chain inspection regimes and that all their sub contractors truly respect workers rights and safety.
We also need to make sure that that the huge contract pension and insurance funds that don't have any trustee oversight are brought into the responsible investment fold. If you pay into any product that invests in any part of this supply chain you can't wash your hands of your responsibilities as a owner and a beneficiary of what is done in your name.
Why don't we make UK companies and investors legally responsible for the reckless mass deaths of companies they invest in as they are for the manslaughter of workers they directly employ in the UK?
Also, before we get too smug, don't forget the 20,000 plus Brits who die prematurely every year in this country because of their work.
