To make our one t-shirt takes around 400 gallons of water and often uses cotton from farms in the developing world. On some of these farms the average age of the workers is 7 years old and there are often reports across the board of breathing difficulties from the pesticides- not to mention the damage done to the hands of the workers from handling them. They need gloves but they can't afford them and the owners cant afford to not use the pesticides.
Having travelled over perhaps 3 countries, our t-shirt arrives on the high street where we pick it up and momentarily wonder- at best- why and how it can only cost us £2.50 (for instance). The reason is that we are not paying for it- they are. The message was and is that as consumers we need to start voting with our wallets and as designers we can influence how people consume, use and behave.
The point was also made that change doesn't have to be about telling people off or what to do- it can be fun and is much more effective and long lasting this way, illustrated in the videos below from The Fun Theory, enjoy :)
