Li Songhai, a professor at the Institute of Deep-sea Science and Engineering, said that establishing nature reserves is currently the most effective way to protect the Chinese white dolphin.

"The white dolphins don't ask for much — just a one-kilometer buffer beyond the coastline, designated as their habitat. With dedicated nature reserves and systematic planning, we can ensure their protection," Li said.

"The vast ocean should hold a place for the Chinese white dolphin," Serres said, adding that protecting the Chinese white dolphin and marine life is ultimately about safeguarding Earth's ecosystem and preserving the home that humans depend on.
