"In all things of nature there is something of the marvelous"
Water Hyacinth a.k.a Water Lily
Water Hyacinth is not only a competitor to rice crops, it also alter the free flowing water in the river and other bodies of water. When I was a child I wasn't aware of those facts because it's a major source of playing materials for me during cooking session with little friends. I also came to admire it's attractive flowers.
Discovering that it has fibers, textile manufacturers found a great way to maximize the use of this flowing creature into something that humanity can use. And instead of mass destruction to avoid clogs on rivers, they converted it to textile.
A proof that even a bane can also be a boon.
