Uh, no. Nonbinary people can make decisions. A river cannot make decisions. If there is a trust for the river, then some human or humans are responsible for making decisions for the trust. So we are talking about an organization of humans that are working to protect the river, not the river itself personified. The organization can sue. The organization can own a bank account. The organization can be awarded damages, provided they have somehow acquired rights to the river. The river cannot do these things. This is an important distinction because making decisions involves responsibility. If you treat the river as a person in itself, that would mean that the river can be blamed or held responsible, which is nonsense. To do so would hide the responsibility of the real humans who are making decisions. In fact, the organization is responsible, and the humans who run it are responsible for their decisions.
