Habitat loss and degradation, disease outbreak, invasive species, pollution, over‐exploitation/overfishing, and climate change are notable problems experienced by freshwater and marine fishes.

Some people offer more prejudice on the sexual orientation because sexual orientation like gay marriages were not seen in the world before. Before the 21st century, the same- sex marriage was never seen or heard about. So, today people display more prejudice regarding this issue because sexual orientation began in the 21st century. Many people are of the view that this same sex marriage is not traditional and hence it is not right morally.
