NPR's Planet Money podcast created a T-shirt and attempted to follow it every step of it's economic journey. An interesting look into the gears and cogs of global manufacturing of an everyday object.

Planet Money buys a barrel of crude oil and follows its journey through the various actors and entities in between pumping it out of the ground and selling it as a final product.

The narrative follows the lifecycle of a t-shirt, from the farming of cotton in the southern US, to China where the shirts are created, back to the US for sale, and ultimately to Africa after donation.

"Rather than a story of how people were competing - how do I make a faster T-shirt, a better T-shirt, a cheaper T-shirt - what I found is that the story of the T-shirt and why its life turned out the way it did was really about how people were using political power," she says. The current backlash against global trade is a direct result of this kind of political interference, she believes.
It was a lovely idea, but he just couldn't make enough to sustain the business.
Cotton farming has had a devastating effect on drainage basins across the world.

Closer to 10,000kg for 1kg of cotton if these Guardian statistics [0] are correct. While still quite wasteful - it is half as wasteful as you claimed (but still more wasteful than nearly everything)

However, suppose I use 10,000 L of water to irrigate my cotton plot. A lot of this water is lost to evaporation and transpiration. A little bit is bound up in the non-harvest-able parts of the plant too. However, none of this water seems like it's really "lost"--it eventually comes back as rain or snow, right? If we're not spending tons of energy moving the water around, this doesn't seem too awful. The worst possible outcome seems like it would involve the water evaporating and then returning as rain over the sea, which would make it more expensive to reuse as fresh water.
On the flip side, I can imagine that some water is also contaminated by the processing in a way that makes it expensive or impossible to reuse. That seems much worse.
It could be worth weaving in Morocco rather than China, but I guess the sewing is only in Morocco to cut the lead time between sewing and selling in Europe.
