One of the main reasons plant diseases like cankers are spreading is that this is mother nature's way of controlling too much of something. Thousands of hectares of rainforest and Mediterranean climate types are being cleared for monocrop plantations. Lemons, limes, pineapples, pears, apples, oranges, etc. These diseases occur because they are protective devices used to maintain biodiversity. The same is true for insects. Nature maintains a balance through many different means. The bottom line for farmers is to stay diversified so that if one crop fails, another crop produces. What will likely happen is that anti-canker genes will be found from one fruit tree and transplanted into others. Essentially a GMO. However, that doesn't really solve the underlying problem: that humans are putting real constraints on the environment. Eventually, the cankers would adapt just like diseases to antibiotics. This is why organic food production is so important and your first point is very valid. The less we tinker, the more stable the nest.
Good question. Switchgrass is a native prairie grass eradicated from much of its former range. Cellulosic ethanol could be made from wild prairie grass. To bioremediate and restore old range lands would a be a service and not a disservice.
I read on msn.com that Sunopta is changing their ticker symbol. This usually indicates a name change that reflects the companys core business. It also gets a new analysis following along with the recognition we have all been waiting for. Look for at least a dollar gain in the short term and skies the limit for the future. This is great news for us longs!!!!!!!!
