Stephen Hawking's warnings: What he predicted for the future

Stephen Hawking's warnings: What he predicted for the future
By Paul Rincon Science editor, BBC News website
Stephen Hawking's fame was founded on the research he did on general relativity and black holes. But he often stepped outside his own field of research, using his recognition to highlight what he saw as the great challenges and existential threats for humanity in coming decades. His pronouncements drove headlines in the media, which sometimes proved controversial.
Leaving Earth
Hawking was clearly troubled that we were putting all our eggs in one basket - that basket being Earth. For decades, Hawking had been calling for humans to begin the process of permanently settling other planets. It made news headlines again and again.
Hawking's rationale was that humankind would eventually fall victim to an extinction-level catastrophe - perhaps sooner rather than later. What worried him were so-called low-probability, high impact events - a large asteroid striking our planet is the classic example. But Hawking perceived a host of other potential threats: artificial intelligence, climate change, GM viruses and nuclear war to name a few.
In 2016, he told the BBC: "Although the chance of a disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next thousand or 10,000 years.

He was confident that humans would spread out into the cosmos by that time (given the chance), but added: "We will not establish self-sustaining colonies in space for at least the next hundred years, so we have to be very careful in this period."

Be grateful for even the smallest thing, blessings come in many disguises.

I remember seeing a programme about the amount of not just food but other things too, clothes and householdware, items that have been classed as imperfect and cant be sold in the shops, also things like used wheelchairs and stairlifts that are no longer needed. The programme mentioned a few organisations that help to provide these things to people that really need them. One of them might have been Foodcycle, I'm not sure, but also a lot of supermarkets now have a trolley or box at the exit for shoppers to donate something from their day's shopping, may be a tin or some fruit, and at the end of the day it gets distributed to homeless and food banks.

There is a lot of good being done behind the scenes that we just dont hear about.
