The circular economy; 2. Loss of biodiversity.

Mycorrhiza 2. coin P1000826

There is a 50 p piece just above center in this picture. it is surrounded by white hyphae of soil fungi, mycorrhiza, which are digesting residues of tarmac.Without mycorrhiza, the human population would cease to exist.

The Science: Does this loss matter?  Well, the environment we live in is a bit like a brick wall with the human race sitting (we think) on the top.  There is a limit to how many bricks you can take out at random from here and there in the wall before the whole lot just falls down. If one species dies out, there is always a change everywhere else.  It may be very small, but there is a change.  So do not take too many bricks out.

The bad news: It is estimated that in the last 50 years we have lost 60 % of all our species. How close are we to real disaster?  We do not know but already too close for comfort.

The good news: We have made a start with things like national parks, the global seed bank at the Royal Botanic Gardens Kew, attempts to limit destruction of rain forest. There is a growing awareness that we need to do much more and urgently.

P,S.  Generally, I plan to post a Sunday blog on The Circular Economy and environmental, waste or food piece on Tuesdays or Wednesdays.
