A big welcome to the Einztein community of learners for new arrivals.

I’m not a biologist but a recent article in National Geographic caught my eye. Let me sum it up for you.

A recent study by Aquascience (http://www.aquascience.co.uk/) finds that the life of the British Mayfly has been cut short by 50% due to warming temperatures. As it was, mayflies only lived about two years, mostly as aquatic larvae, and got to enjoy their adulthood as winged creatures for only a few hours. Now, their lifespans have been reduced to one year! What does this mean, other than reminding us that life is short? The younger the mayfly dies, the less eggs it hatches during its life, so the potential for disruption to the food chain is enormous, since the mayfly is an important food staple for fish and birds.

This makes me wonder what other changes we will discover as environmental changes accelerate.

    Fascinating. Thanks for the explanation. Good thing we have a biologist around.

    Jason, thanks for that education. What I gather from your lucid note is that not only we are all connected but the connections are delicate and quite complex where any excess anywhere in the chain can throw the entire system out of balance. And a series of corrections are needed before we have that balance restored. Or is that at all possible?

    In my mother tongue, Tamil, (a South Indian language) there is an ancient saying: 'anything in excess is poison - even elixir'.

    absolutely, and that is a wonderful saying.

    as for the “corrections” needed, the main one is simple to say but complicated to do: stop burning carbon.
