While
the herbivorous species that depend on green growth might do better in some waters, the carnivores — which make up an important part of the fishing industry's haul — might be at risk.
The study also highlights the benefits of alternative fisheries restrictions, including bans on specific fishing gear such as small - mesh nets and restrictions on
herbivorous species.
This idea helps explain how we started out as a small, apelike,
herbivorous species 6 million years ago in tropical Africa, and after a history of origin and extinction of species, what's left today is us: a single species all over the planet with an astonishing array of abilities to adjust.
Many hundreds of
herbivorous species have switched to novel, sometimes toxic, food sources introduced by humans and have come to specialize in consuming those new resources.

herbivorous species.
