> I'd say there is arguably no environmental disaster in meat production As you may know, human population is growing exponentially and has been doing so for a century. To meet the demand for meat, we have grown the poultry and cattle's population accordingly, increasing the energy, water and food spendings uphill (after all, they too need to be nourished). Especially in the US, to maintain low prices, those who set the customer price (such as McDonalds) have been forced to rationalise the whole chain of production, putting a lot of stress and liability on farmers. However, the human population is still accelerating tremendously, and meat is still among the most costly food per kilogram we eat, not in terms of money spent by the customer, but in terms of energy wasted along the whole chain. Fishing has a similar crisis; regulation became necessary to maintain fish population to a sustainable level, and avoid having fish locations simply disappear. At a fundamental level, the reason life can thrive on earth is energy from the sun and the Earth converted to plants which are consumed by animals and fungi. Every step of consumption between plants and humans is wasted energy, given that the planet's energy is not limitless, and that we humans must tap that supply carefully if we ever hope to colonize another planet.
