Thank you for your reply. The answer is yes. As Richard Dawkins describes:
If there are ways to reduce this suffering, we ought to pursue them. One may object that we shouldn't interfere in nature, but
what's natural doesn't equate to what is right. In any case, humans constantly intervene in nature already; I'm simply arguing that we should intervene to reduce the amount of suffering in nature. Just today,
footage emerged of an elephant being rescued after it fell into an open drain. Does anyone seriously think that we ought not to have intervened in nature to prevent this from occurring?
Another objection is that this would have an impact on ecosystems such that total suffering in the wild increases, perhaps due to a population explosion of herbivores, meaning that more herbivores die of starvation, thirst and disease. I'm not arguing that we should intervene until we've done the ecological research to prevent this from happening. One way of doing so would be to reduce populations of herbivores simultaneously, through fertility regulation via family planning or cross-species immunocontraception.
Are there any feasible techniques for phasing out predation currently out there? Fertility regulation would be one possible technique. Another would be to genetically engineer predators to become herbivores. There are already
serious proposals to genetically engineer mosquitoes to stop them from transmitting malaria and Zika, with a good level of debate going on about the possible ecological consequences. If we are willing to consider intervening in nature to prevent suffering from being inflicted on humans, we should be willing to do so to prevent suffering from being inflicted on nonhumans.
And, as I've noted, we already intervene in nature in a plethora of ways. This will happen whether we like it or not, but when considering what actions we could take, we could also take into consideration the possibility of reducing carnivorous and increasing herbivorous populations.
If we were in a position to design and create a world, would we not create a world in which sentient individuals could survive without inflicting huge amounts of suffering on each other? If we encountered an alien civilisation who had abolished suffering on their planet in the wild, would we seriously go up to them and say that they should reverse the changes that they have made, thereby returning the planet's individuals to the state of agony central to Darwinian life?
Plenty of other philosophers and thinkers have explained it much better than I have. The Oxford philosopher Jeff McMahan
makes a compelling case for this in the
New York Times, and his response to the people who didn't read his article properly is
here. The economist Tyler Cowen has also
argued in favour of what I've proposed, and it is discussed
here by the economist Yew-Kwang Ng. The moral philosopher Peter Singer says that in theory it would be justified, although he is, rightly, very cautious about trying to do anything significant with our current level of knowledge: he has included the topic of predation in some of his
lectures. The philosopher David Pearce is interviewed about it
here.
