Has anybody watched Breaking Boundaries? It's worth a look. It seems the likelihood of us all going vegan/vegetarian is approximately zero, unless we want to accelerate the planet's death spiral. Breaking Boundaries discusses the tipping points that are going to fuck the planet, and the one we've already reached and breached is chemical fertilisers. They've poisoned our waters. It's so bad that the Baltic Sea, which used to be full of cod, now contains no cod, and it's due to runoff from cemical fertilisers poisoning the water. So it would appear that the best way to save the planet is to cut down on vegetables, don't bin the ones we buy because there a bit old, and instead of chemical fertilisers, use the natural fertilisers from the animals we eat, because unless we cut back on chemical fertilisers, we're doomed.
