New Study Claims That Humans Are to Blame for Worst Ocean Extinction Event Since the Chicxulub Asteroid

If you also feel sorry for what the dinosaurs had been through after the Chicxulub impactor collided with Earth roughly 60 million years ago, only God knows what could have happened if humans were also around at that time. Probably dinosaurs had more reasons to fear us rather than a space rock. 

Jokes aside, for now! A new study by Princeton scientists and published in Science claims that underwater life is in the greatest danger yet since the extinction event of the dinosaurs. You can blame it on carbon emissions levels – if they go out of control, marine life will ultimately run out of oxygen and food.

How it could work

Surely we’ve all heard much better news about the environment. Researchers explained in the release:

As greenhouse gas emissions continue to warm the world’s oceans, marine biodiversity could be on track to plummet within the next few centuries to levels not seen since the extinction of the dinosaurs.

If you’re a fan of extinction events, we’re here to disappoint you! There’s still a chance to prevent the disaster from happening, although we don’t know exactly how feasible it is. 

Justin Penn, a co-author of the study, explained:

The silver lining is that the future isn’t written in stone,

There’s still enough time to change the trajectory of CO2 emissions and prevent the magnitude of warming that would cause this mass extinction.

The asteroid that killed the dinosaurs roughly 60 million years ago was also known as the Chicxulub impactor, and it measured between 10 and 15 kilometers wide. The aftermath of the collision was arguably deadlier than the collision itself, as it has raised enough ashes in the atmosphere to block the sunlight for hundreds of years. Lacking sunlight, plants couldn’t produce oxygen anymore for the dinosaurs to breathe.
