I spent last week at my family cottage in New Brunswick. I have been coming to this place for 37 years, including spending every summer all summer when I was a child. It still has few of the conveniences of many modern cottages, though now we have running water (though naturally high in uranium) and an indoor toilet. The conveniences installed at many other cottages on the lake, like showers and dishwashers, are causing real trouble for the lake ecosystem. When I was a child, hundreds of bullfrog tadpoles lined the leaf litter on the shoreline, splashing out an impromptu honour guard as you walked along the beach. Those frogs are mostly gone today; I haven’t seen a tadpole in the lake for years. This may have been caused by stocking of the lake with bass. Also, however, by each August, the water grows thick with algae, indicative of eutrophication. Glad to have been there last week, with the water clear if frigid.
