If British people truly care about the environment and the carbon footprint of their food, they should opt for New Zealand lamb rather than homegrown lamb.

In an article that looked beyond the hype to find out what conscious consumers should really do if they care about the environment, British newspaper the Guardian suggests the UK looks Downunder for its lamb.

"Imported New Zealand lamb has a lower carbon footprint than British lamb, concluded a 2009 report for Defra," the article states.

It goes on to explain that New Zealand lamb is actually reared at a lot lower intensity than British lamb, making it more sustainable, even when you account for travel.

"Kiwi lamb is reared at such a low intensity that, even after shipping, it uses less energy. Of course, there are other issues around sustainability that mean you may still want to support British sheep farmers, but that starkly illustrates how 'food miles' are no measure of a product's green credentials, and that there are no easy answers to global warming," it adds.

The article made other bold claims, including suggesting people ditch the almond milk but stick to clingfilm, especially if the focus is on not wasting food (therefore wrapping it in anything is still better than throwing it out).
