Don‘t think about microwave vs. stove. Instead, do the following: 1. stop buying meat 2. stop eating meat 3. stop buying dairy-based products 4. stop eating dairy-based products 5. stop eating eggs, honey, fish 6. use public transport, if possible 7. don‘t fly, if possible Congrats, you now are an environmentalist.
Congrats, you are actually just an inconsequential stooge. Environmental corruption and depletion is not a consumer problem, at least not directly. It is a product of industrial production processes. Eat meat, eat dairy, preserve your health and your brain in doing so, and find ways to create industry that is clean, that would make you an environmentalist... maybe... if you successfully altered the system. Stop prete…
An example might help: Elon Musk is not, AFAIK, vegan. But he's done a lot to popularize electric cars, having far more impact than he could by changing his diet. Likewise, the Beyond meat people have probably done a lot more to reduce meat consumption than they could ever outweigh by eating steak every meal for the rest of their lives. (I am actually not clear on the net environmental benefit of using gas vs. making more batteries, but let's say for the sake of argument that electric cars are an environmental benefit, since it's just an example.)
