I do, what you do (and are doing) is trying to say that something you do according to your own set of ethical values is also intrinsically better for the environment. It isn't.
You'd have more impact by not eating veg than beef (see above graph) and that's not taking into account the hectares of plastic covering the planet to grow them.
Would I suggest people stopped eating veg?
No.
From the UK soya growers association website:
The Protein Problem
The majority of plant based burgers, sausages, nuggets and steaks on the market today are made from some form of protein isolate, with the dominant varieties being soy and pea. Much of this is produced in the US and Canada, where both crops are grown in enormous quantities. Isolating protein from soya or pea is a large scale industrial process, requiring a good deal of energy and water. Often, solvents such as hexane are used and the resulting protein is highly processed, with an awful lot of environmental impact embedded into it. When making plant based products, these isolates can be extruded to give them texture, either in high moisture systems to make a meat like paste, or through a lower moisture system to produce the dried, textured vegetable protein known as TVP.
If you want to make vegetable based food products that replicate the texture of meat, these sort of extruded isolates are the best starting point. Currently however, there is a complete lack of processing facilities to isolate vegetable protein in the UK, meaning that the majority is imported from the US and Canada. It is perhaps not that well known that as the UK market for plant based products develops, most are made from protein grown thousands of miles away that has been put through a highly energy and water intensive process. A recent study on the environmental impact of soy protein isolates showed that many have a global warming potential higher than that of unprocessed pork and similar to beef, which is perhaps problematic for a manufacturing sector that trades on its environmental credentials.
