But I've had second thoughts about the knotweed, because at least we can control it, with some effort. Imported fungal diseases, like Dutch Elm or Phytophthora ramorum or Batrachochytrium dendrobatidis, are much harder problems.  |
This thread was posted as a sort of experiment to see the views of the fellow wabbers. Your post is the sort of response i was hoping for, thankyou. I personally think we have done too much harm playing god, that often trying to fix problems can cause other problems on a smaller or larger scale. Its often best to let nature takes its course and find its own solution.
