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 whole 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.
Welcome to one of the largest collections of footwear(鞋类)in the world that will make you green with envy. Here at the Footwear Museum you can see exhibits(展品)from all over the world. You can find out about shoes worn by everyone from the Ancient Egyptians to pop stars.
Room 1 The celebrity(名人)footwear section is probably the most popular in the entire museum. Stared in the 1950s there is a wide variety of shoes and boots belonging to everyone from queens and presidents to pop stars and actors! Most visitors find the celebrities' choice of footwear extremely interesting. | Room 2 Most of our visitors are amazed —and shocked— by the collection of “special purpose”shoes on exhibition here at the Museum of Footwear. For example, there are Chinese shoes made of silk, that were worn by women to tie their feet firmly to prevent them from growing too much! |
Room 3 As well as shoes and boots the museum also exhibits shoe-shaped objects. The variety is unbelievable. For example, there is a metal lamp that resembles a pair of shoes, and Greek wine bottles that like legs! | The footwear Library People come from all over the world to study in our excellent footwear library. Designers and researchers come here to look up information on anything and everything related to the subject of footwear. |
