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.
1) this organisation was founded in 2013; they've been thinking and researching into this for a while, this wasn't a rash intervention.
2) they didn't block the river flow! 100% that would be very dangerous. The have a capture device on the surface of the water. Wildlife and water travel freely under the surface.
3) the mission statement of this organisation is about helping wildlife, so I reckon they think a lot about the impacts that anything they do can have on wildlife.
How do you know they didn't stop to ask if they should? And concluded after, detailed and deep study, that yes, they should. Perhaps they (or someone else) already did studies of the impact of blocking rivers partially or totally? Are you, perhaps, making assumptions about what they did without first stopping to think if you should make such assumptions?
