I'm calling for a moratorium on the river barricades until we can determine that it's not damaging to the environment. They were so occupied with whether they could they didn't stop to ask if they should. This is why they need to teach ethics in school next to engineering.

Messing with fragile systems like this is dangerous. Many studies show that blocking river flow causes the extinction of species. Until we can be sure that this is safe, we shouldn't do it.

We should first study it over a reasonable period of time (say 20 years) before doing anything like this. Humans think they can just modify the environment without consequences. That is the root of the issue. We need real change.
