This isn’t something that gets solved by just hoping people’s individual lifestyle choices fix it. Production has to be scaled back, and market economics is clearly not capable of that sort of conscious decision making.
‘The Market’ is not capable of spontaneously deciding to make less profit for sure. What is capable of, and in fact the only thing it does is responding to demand. If the demand for highly polluting products like meat and fish fall, it will pivot to products that continue to see high demand.
This is why individual action does matter. You can’t just offload all responsibility for making better choices onto the companies and act as though you are forced to consume what they produce, andnothing will change unless they change.
To be clear I’m not advocating for everyone to be vegan or anything like that. One plant based meal a week could have huge impact on the climate
