Study shows environmental impact of 57,000 products sold in supermarkets

This is very poor science, albeit well-intended. Each ingredient and product has a unique lifecycle depending upon its origin, manufacturing processes, packaging and the resulting use of the product by a vast number of people - do they recycle the packaging for example, do they waste half of it etc. You cannot ignore all the unknown data, skip happily to your conclusions and still call yourself a scientist.

To which might be added, most people ignore such labels. Most UK food has a traffic light system to denote how high or low it is in salt, fat, sugar etc. Only a tiny proportion of the population take any notice of it when making buying decisions.

Manipulating behaviour is difficult, expensive, rarely works and is ethically questionable. A recent attempt to reduce alcohol use saw a minimum price fixed for booze. People just carried on buying as much as they usually did but had less money left over for healthy food. There are better ways to spend research money.

Don't worry, you will all be able to eat insects to save the planet. Already being market now and reported on other major news sites.

Except that will accelerate our own demise (which is what they want). Insect numbers are on the decline:

More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century (The Guardian, 2019).

I'll stick with similar things to what Schwab consumes, thank you very much.

Anything that has a high carbon and a high water foot print should be gradually replaced.

Except that the insects used are crickets, and are factory farmed.

Agree - If this is a study that shows the environmental impact of 57,000 products sold in supermarkets, but of these products, about three percent had their composition fully disclosed, then what is the point?
