  Because plant based farming is unsustainable, harmful to the climate and contributing to global warming. High yield farming uses a lot of fossil fuels, uses up land and water, pumps tons of herbicides and pesticides into the environment, turns lakes and oceans into massive underwater deserts where neither plants or fish can survive, and creates mono-cultures out of bio diversity. Agriculture has it place but it need to be done sustainable and without nitrogen fertilizers. Seaweed and shellfish farming has one of the lowest production footprint of all foods, don't need herbicides and pesticides, don't need fresh water, and don't need fertilizers produced by fossil fuels, and do not use up high quality land. The only other kind of farming that beats its efficiency in land and CO2 are insect farms. Shellfish can also be used to clean polluted water, but for health reasons they then can't then be sold as food. The output can however be used as an organic fertilizer, depending on the amount of toxins they have absorbed and additional cleaning process, so there is some potential for an combination between plant crops and shellfish farms. If 50% of all land was turned into man-made desert we would notice and get worried. That we have already done this to the worlds lakes shows how insanely harmful modern high yield agriculture is. Add that with the massive decline in global insect populations, with 75% loss in 26 years, and we can't just replace one harmful diet with an other.
