Set in a dingy comedy club, Greenpeace's Christmas ad sees a roast battle between two main ingredients of x-mas lunch - turkey and potatoes - to hit home a poignant message about sustainability. Not one for the traditional Christmas ad format, most years Greenpeace throws an 'alternative' spot into the mix. This year, before people tuck into their roast dinners, it wants them to reflect on the negative affect such practices have on the environment.Greenpeace UK has estimated that an area of land the size of Glasgow would be needed to grow enough soya to fatten 10 million turkeys - the amount eaten by Brits every Christmas. As two-thirds of the UK's soya is imported from South America, the charity claims that the UK's turkey tradition is having a detrimental effect on the continent and its deforestation issues. Avoiding a guilt-trip montage of various scenes of the destruction, instead, Greenpeace is using comedy as a medium - acting out the roast battle between a potato and an 'evil' turkey. Created by Nice and Serious, the spot opens with the Turkey saying: "It's great to be here roasting the 'humble' potato. People call it a 'staple food' because you'd rather staple your lips shut than eat it." To which the potato replies: "Well that's rich, considering people only eat turkey for one day of the year. Probably because they need the other 364 for their mouths to rehydrate." After a number of of back and forth burns, the potato takes the roast 'too far' by telling the audience about the environmental impact it takes to feed turkeys - exposing the ultimate Christmas conspiracy.
