Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition(营养)“depending on who needs it”.
Nitrogen(氮)and carbon are shared through miles of underground fungi(真菌)networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons(神经元)in our brains, and when one tree is destroyed, it affects all.
Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.
“We didn’t take any notice of it” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

Dear David,
I’m glad you would like to share your feelings with me. It’s hardly surprising that your feelings of not being “grown up” have come on strongly at this point in your life, just before you’re about to become a father. You are asking: will I make a good father? How will I deal with? Should I have brought another little person into the world? Can I provide for it? Help! I think nearly every sensitive about-to-be-parent must have these occasional feelings of self-doubt and inadequacy(不适)before the birth and it would be most unusual if you didn’t share them.
It’s difficult, honestly, to feel grown-up unless you have something less grown-up to relate to. The boss with a hen-pecking wife may feel like a seven-year-old when he’s at home. But as he walks through the office door, and knows he’s going to be surrounded by staff looking to him for advice, he grows into a fully mature(成熟的)man. And I think it’s a mistake to imagine that we all feel, as we age, a kind of progression of states, from the baby to the adult. Most people feel, on Tuesday, about three years old, and on a Wednesday, around 80. I remember feeling very grown-up at eight, a time when I was weighed down with responsibility. These days, much older, I can, in the company of people I feel at ease with, feel like a young girl.
There’s a common remark that “all men are little boys”, but it’s not true. It’s more true that men often behave like little boys. But nearly all people, at some moments in their lives, are able of great maturity.
Once your baby arrives, you’ll soon feel less childlike, or rather, less often. When your child tries to put its fingers into the electric plug, the adult in you will rise up to prevent it. You’ll see you have very little in common with a needy child, particularly if it’s looking to you for comfort and support.
Comfort yourself, David, with two truths. One is that your friends laugh when they talk about this subject because they, like you, feel frightened. And remember that people who haven’t grown up don’t go around talking about the fact that they don’t feel grown-up.
Hope my advice will be helpful and good luck to you and your little one.
Sincerely Yours,
Miss Advice

Do you know that many clowns go to school to learn how to be funny? How would you like to go to that school? You could learn how to walk and talk like a clown. Then you could make people laugh.

Now they look silly. They are ready to go to work! You can see clowns at the circus or parade. They do funny things to surprise people. Ten big clowns may get out of a very small car.
