As benign as it may look up close, the tiny seaweed Caulerpa taxifolia can wreak quite a bit of havoc on coastal ecosystems. This super algae is very adaptable; it also grows fast and spreads easily. Eric Noel Muñoz gives the details of this plant's incredible invasion, shedding light on the risks of introducing invasive species into new ecosystems.
Lesson by Eric Noel Muñoz, animation by Eli Enigenburg.

Eric Munoz is a hero. I am a scientist and live near the lagoon where this incident happened in California. This genetically modified algae meant for aquariums cannot be released in the wild. Period. This video has shown that there is nothing that can stop this algae from spreading with the exception of Eric's treatment. What also helped is that this was caught very early after some moron dumped his/her aquarium into our lagoon. Also helpful is that the lagoon was relatively isolated from the ocean so treatment could not be affected by large waves. Since this algae can break off and sprout elsewhere, it can spread quickly and take over an area rapidly. It will wipe out the ecosystem! Public awareness is the best way to avoid something like this again.

Some scientist says that this have much more positive effect on the environment than negative. It removes extreme amount of pollution and able to grow in areas where other plants already burned out completely. I dived in area where they have this and there were some small fish between them. Small fish attract and feed big ones so there is a circle. There is and were an evolution of plants just as much as animals and it is not controllable.

There is only one natural enemy of the plant, and it is an snail. It's not a very fast snail either, and would be as Eric Munoz put it in a lecture "like burping in a hurricane". The animal would not help much. Now if we could genetically mutate it to be better... that would be cool.

That is why genetically modified organisms are very dangerous. Sometimes just a slight difference in DNA could have a huge impact. For example, a scientist once genetically modified a tomato so that it wouldn't rot. However, it was later found out that those tomatoes can cause cancer. Humans have been genetically modifying organisms for thousands of years and they still can't get it right. They should just leave the process of creating organisms to nature. We are not science experiments, we are people!

Evolution doesn't happen just like that. It is when those who can't survive die off, and those who can survive live on and breed. You can't just spontaneously be immune to toxins, unless you were born with it, or if you slowly, over many years, build an immunity to it. Fish don't live long enough, and likely don't know of the method to build immunity to it. So, if it manages to crowd out the local life too much, there will be a pretty massive die off with only a few if any surviving fish. But after that point, it will slowly get better, but will still be plagued by this incredibly invasive species. But, I wonder if we can introduce this seaweed to China's Yellow River to make it almost drinkable...or if it would just die from the pollution.

Considering almost nothing could grow in the Yellow River because of how atrociously it was treated, I kinda doubt even this killer algae could put down roots there. But yeah, most people just blow off major issues by saying "aw, we don't need to worry, everything will just adapt and we will live happily ever after." His comment seemed equally dismissive so I was simply explaining evolution is not magic.

who cares about the un altered natives it's the same animal just given an advantage over the introduced pest. also if the only thing holding progress back is funding then there is a problem with the system not the scientific method.

And I have another invasive protozoan culprit that’s already an invasive species that can do as much damage as the killer algae, And this protozoan is the same one that causes amoebic dysentery,I’m talking about entamoeba historlitica , or flesh eating amoeba to make it easier to understand and say, and this protozoan is a very small but very aggressive amoeba, and this little thing can reproduce really really fast, up to 35 million descendants in a day, and is faster reproduction than aphids or even bacteria, and that reproduction is what I like to a very good candidate for an invasive species, and there is almost no other organism that can match that reproduce as this amoeba, and this parasitic amoeba is also one of the oldest known invasive species in the world!
