I wonder which direction it vortexes
when you're just on the equator?
I heard they keep changing their rotation.
Re the eucalytus trees: I also heard they grew way too fast because there weren't any natural enemies in the US, so the wood was soft and unusable.
The worst plague here are the ailanthus trees. they were imported from China around 1900 and immediately spread everywhere. If you have one big tree, you have 100 saplings within a few weeks. Some of our neighbors have several mature ones, so all we do is digging out small ailnathus all summer long. And they grow helluva fast! Within 5 years you have a tall tree, and after 10 years it'll easily tower your house. And they grow _anywhere_. I've seen some grow right out of the mortar joints of a brick wall, growing _inside_ a basement, right out of concrete sidewalks... we jokingly call them "the green demolition".
