The sharp tips of the giant agave are there for a purpose–to fend off predators such as javelina and hungry cattle intent on a juicy meal.
Too bad somebody didn’t tell the spiders, who found the spines to be perfect tent poles for their webs. Or the wind, who discovered the web to be a perfect receptacle for some spare leaves just blowing around.
It is nice to find something that can be put to more than one useful purpose. Nature is resourceful that way.
The first rule of intelligent tinkering
is to save all the parts.
