Is it possible that the trees can think in longer terms than we do?

We know they have excellent parenting skills.

Take this fir tree. This younger tree here is its offspring,and it requires constant attention.

It's hardly young by our standards, 60 years old.

But young trees don't know that if they grow up too quickly, there will be too much air in the cells of their trunks.

Later, when the stormy winds and predators come, they'll be weak and vulnerable.

Like the young of other kingdoms,the fir wants to grow into the light as soon as possible.

But the mother fir shades it with her branches so that it cannot binge on sunlight, and grow up too fast for its own good.
