Last weekend we went to the Matsuyama City Environment Education Center to learn about biotopes. These are fragments of ecosystems that people choose to maintain and conserve as a favour to nature. We learned how chemical fertilizers have effectively destroyed significant fertility in the countryside, and that conserving it in ponds and tubs may be necessary so that one day the countryside can be restocked when 'we' run out of fertilizer or see the folly of it.
The tub of water proved to be a lot more interesting than at first glance. It had shrimps, tiny fish, and dragonfly lavae living in it. I think we'll be keeping a few of our own, besides the planned pond.
