Everyone leaves a legacy.

But a legacy can change over time as new generations re-examine old reputations.

From Wundery and Goalhanger Podcasts, I'm Afu Hirsch.

I'm Peter Frankepan, and in a brand new series we're exploring the lives of some of the biggest characters in history, from Napoleon to Picasso.

And asking, what does their past tell us about our present? This is legacy.

Follow now, wherever you get your podcasts. This is a

CBSI in the world. I'm John Bachelor with Professor Peter Francopan. The Earth transformed an untold history.

This has to do with natural resources and exploitation. and Peter's reporting that one cotton shirt requires 2,700 liters of fresh water.

I'm stunned, Peter. Is that a factor in the cotton industry? I know they've done a lot of

work about blood cotton but the use of water seems

reckless is their comment on this generally yeah I mean that that amount of

water to just just under 3,000 liters of fresh water is the equivalent of a person's drinking needs for two and a half years.

A pair of genes is about three times that amount.

The global fashion industry produces around about 10% of all greenhouse

gas emissions averaged out and some projections put it that in the next 20 years that's going to trouble.

So I think that I think that my job as an educator and as a

professor is to give people more knowledge than perhaps they had beforehand and to let them make their own decisions about how they use that.

But I hadn't realized the level of waste, for example, around food.

So we waste globally around 930 million tons of perfectly edible food that if you put that all in 40 ton trucks with stretch around the world seven times around

231 million trucks.

So there are all sorts, sorry, 23 million trucks

with stretch around the world seven times round.
