A radical change in our approach to ethical treatment of other animals is required to safeguard their future. We could, and should, replace farm animals for food with plant-based food, and/or cultivated “clean” meat, reducing the ethical impact of humans on animals and freeing up land for wildlife. We must address the likely demise of predators and focus on the conservation of animal species on earth. Finally, there is the possibility to secure animals’ future by colonisation of other planets, moons, or galaxies, and the likelihood of this, its desirability, and advantages and disadvantages are considered.
