The findings reinforce prior studies that have shown that trying to debunk skeptics never works, and perhaps now we know why. Conspiracy theorists don’t join social networks to learn, they join them to hear comforting reinforcements of their own ideas. And if you disrupt their happy place with scientific facts, you’re not going to get very far. The study also suggests that social media, especially Facebook, has provided a particularly strong breeding ground for extreme ideas by creating a forum for loners to establish large communities that echo similar, strange beliefs.
Young fish become hooked on eating plastic in the seas in the same way that teenagers prefer unhealthy fast food, Swedish researchers have said
The fish that did hatch in these waters with high quantities of micro-plastics were “smaller, slower, and more stupid” than those that hatched in clean waters, lead author Dr Oona Lonnstedt, from Uppsala University, said.When exposed to predators, about half the young perch from clean waters survived for 24 hours. Those that had been raised with the strongest plastic concentrations were all consumed by pike over the same period.
“They all had access to zooplankton and yet they decided to just eat plastic in that treatment. It seems to be a chemical or physical cue that the plastic has, that triggers a feeding response in fish,” Dr Lonnstedt told BBC News. “They are basically fooled into thinking it’s a high-energy resource that they need to eat a lot of. I think of it as unhealthy fast food for teenagers, and they are just stuffing themselves.”
