Comment by the expert
Gireg Allain: There is some interesting information on flora and fauna, but unfortunately there is a lack of information on certain parts, such as ecological threats due to the human species. We would have liked more images of the environment, in particular underwater images to be able to estimate the accuracy of the aquarium.
Aleksey Malyshev: There is practically no description of the environment. What animals live along the river, what plants – it is unclear.
