There was an interesting documentary a few years back about Uncertain, Texas and a fisherman dependent on a lake there to earn a living.

An invasive weed was starving the lake of oxygen, which I had no idea could happen and killing off wildlife. The doc covers other subjects, but on this particular one it was a good example of the effects of something like this.

I haven’t watched it since 2017, but I think it had to do with the thickness of the plant stopping sunlight from penetrating and specifically interfering with photosynthesis. “Salvinia” I think it was.
