Answer:
Yes, the time and effort spent are worth it.
Step-by-step explanation:
Yes, the time and effort put in to stop the spread of fungus in Lascaux Cave are worth it. Scientists believe that it due to rise in temperature inside the caves and possibly global warming has caused the spread of fungus in the caves.
The cave holds a series of cave paintings which are believed to have been painted by early European settlers around 15,000 to 17,000 years ago. The last remains of historical paintings drawn by our early ancestors might be lost if they are not saved.
