Plants literally talk to each other and have a character as species. Survival of the fittest is programmed into trees. This is 45 minutes long, but well worth watching. After watching you may never see trees the same.
From The Film Makers:
"When we think about plants, we don't often associate a term like "behavior" with them, but experimental plant ecologist JC Cahill wants to change that.
The University of Alberta professor maintains that plants do behave and lead anything but solitary and sedentary lives.
What Plants Talk About teaches us all that plants are smarter and much more interactive than we thought! "
