That is amazing. It seems there is no happy solution to this problem. I have read some more about the subject since watching the video. It seems the government has declared hippos to be an invasive species (June '22), and the remedy may include hunting them down and killing them.
What I think of when I read this (besides the unhappy outcome for the animals) is the economic resources diverted to deal with the hippos. There is already great need in Colombia. That money could be used for education, healthcare and other programs to help the poor.
Thank you for sharing the video with me. I will post it on Twitter, if you don't mind.
