Keep in mind Mother Nature produces a lot of extra offspring because most of them don’t get to mature. I remember once seeing films of thousands of baby turtles hatching out of the sand and trying to get to the water before the sea birds catch them to eat. Same with many insects. Even many humans die and suffer from various things and accidents.
Those photos are like one in a million, hopefully not staged. As a shear guess, the people that make or promote those type photos want like minded people to join and or contribute money to a group or club. Its on TV too, they show photos of sick and skinny dogs to get donations. Even the NRA. They send letters about more and worse gun control coming to work on peoples emotions and want donations or new members.
Its good that you care about and have sympathy for sea life but nothing we can do to stop it, like mass shootings. Also just today I read they are deforesting huge areas to mine lithium for battery cars.
