And yet here is a clear indication of a sinister and overwhelming threat magnitudes more deadly than either chappati flour or indeed a degree or 2 (whatever happened to Ozone btw - did we fix it?)

Why are the governments not focussing on this as a major issue eh?

Of course this has happened, a very, very long time ago.

Something similar will happen to us soon - well, "soon" with respect to the lifespan of a galaxy. The Andromeda galaxy is currently hurtling towards us at 500,000 km/h and will collide with the Milky Way in only about 3 billion years time.

If it's 5 billion light years distant, then this has already happened 5 billion years ago and there is already a monster galaxy out there. In fact, it's probably swallowed another set of galaxies by now, especially as it's located in a cluster of galaxies.
