So what would vegans eat if they discovered plants were sentient beings? or are they just against killing things with faces and hearts? Earlier this year scientists proved that not only can plants hear they also makes ultrasonic sounds when they are stressed. After isolating plants in a soundproof acoustic chamber/greenhouse they were able to differentiate the sounds plants make when they are cut or dehydrated. Unstressed plants made very little noise but the stressed plants made frequent clicking and popping sounds. Stressed plants made about 40 clicks per hours while dehydrated plants clicked more frequently as they got more dehydrated. Though they are still unsure how the plants make these sounds they think it's possible that some animals and insects can hear them and avoid the stressed plants.
