One may be tempted to use these findings as a justification for (indirectly) killing sentient mammals. Add studies showing that even plants and fungi have senses and try to avoid harm, and you might as well consider that there should be no ethical considerations around various diets. Since everything living can feel pain for a generous definition of the term and since you kill plants and indirectly insects even on a plant based diet, there is little difference.
Unsurprisingly this is a very common argument against veganism.
But if you truly care about the feelings of insects or plants you should switch to a plant based diet as you'll probably indirectly kill at least an order of magnitude fewer plants and insects, the majority of which are consumed by practices related to industrial farming (large scale deforestation, waterway pollution, feedstock).
