"One way to increase the chances that the suffering of wild animals will be taken into account in research and development is to challenge the biases and assumptions that make it so difficult for us to address it. Most important, perhaps, is the pre-Darwinian fiction that life in nature is harmonious, and that without human intervention, all is fine and good. The truth is quite the opposite. If we imagined that from now on, animals started emitting a red light every time they suffered, then from space, Earth would no longer be a blue planet, but a red and glowing one."
