Why do we need so much water to produce everything?

Question

For example, i’ve read somewhere that we need around 3,7Litres of water to produce a single cigarette and 2700Litres of water to produce a single t-shirt. Why do we need so much water to produce stuff?

Answer 1

First we need water to grow the plants which can be up to 90% water by weight. Then we need water as a solvent since it’s the most common industrial solvent by far. Then there’s secondary processes like washing which almost inevitably used water and the water drank by the workers.

I wouldn’t worry too much about it. We can reclaim and recycle most of that water with a little effort.
