SHARKS do a lot of damage to other living things in the ocean, but as it turns out, they are also lending a hand in the world’s waters, helping restore damaged habitats and fight climate change.

As reported in The Hill, researchers tested how the absence of tiger sharks is affecting seagrass coverage in Australia, finding increased herbivore feeding from a lack of predation exacerbates ecosystem degradation, with sirenians in particular eating more and being eaten less.
