This sounds like a line in a sci-fi movie.
However, it is somewhat true. As the acidity of the world's oceans rises, it kills off predators. This allows jellyfish to thrive!
This acidity is due to the overlooked effect of burning fossil fuels. Higher levels of carbon dioxide in the atmosphere doesn’t just trigger climate change but can make the oceans more acid.
It turns out, lucky for them, jellyfish are immune to the effects of acidification. This allows them to survive while many other creatures are not.
Yikes! This is kind of creepy!!
