Unfortunately, empirical data, good, hard stats, don't exist, and therefore to prove my point, I first of all had to find some proxy way of uncovering how much food was being wasted.
Desafortunadament, les dades empíriques, definitives i bones no existeixen, i, llavors, per provar el meu argument, primer de tot vaig haver de trobar una manera de descobrir la quantitat de menjar que s'estava llençant.
