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 "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.

BLOOD DRIVE & MARROW(骨髓)REGISTRATION

“These patients deserve a chance at a normal, happy future and they rely on the kindness of the strangers to make that happen.

— Daisy, Isabelle’s Mother

Isabelle is the daughter of Daisy and Saman Mirzaei. In January 2008 Isabelle was diagnosed(诊断)with a genetic blood disorder,beta thalassemia. Isabelle’s body

is unable to produce healthy red blood cells. As a result, Isabelle has been receiving blood transfusions (输血) every 4-6weeks since she was 11 months old. A lifetime of regular transfusions can lead to serious medical problems. Her only chance at a normal, healthy life is to have a marrow transplant. Isabelle is an only child, so doctors have started a search for an unrelated marrow donor through The Match Registry. The Mirzaei family asks that you consider helping patients like Isabelle by registering to be a marrow donor and give the gift of life, the gift of blood.
