Do we really need more research on this? Holy shit.
Yes we do, science is better than gut feelings. Repetitive science is also necessary, reconfirming things we know is important, just because we've known something for a long time doesn't mean its correct
Science has proven many times that ingesting microplastics is bad. They even found they can cross the blood brain barrier.
What we need now is to take action to stop this.
The study is about nanoplastics which are bigger. Not that you're wrong since nanoplastics also cross the blood brain barrier (in fish), we just don't know if they have any adverse effects on humans yet.
They probably do, but I'm not a biologist. They may have no adverse effects other than piling up at the levels we are currently consuming. The adverse effects are still being studied:
