Is it pace of movement? Does it depend on the way others around you move? Should sprinters be required to wear a helmet if speed and congestion are criteria?

Light pollution, glare and light trespass are all easy environmental problems to fix. If we can’t (or won’t) fix this, then what chance do we have of reducing or reversing other environmental issues?

All you ever hear is that something is being tested… it seems that there is more money to be made in ‘support’ medicines

To me that is the fundamental question which humanity has too ask itself, and, depending on the answer, ask many more about our role in the world and our responsibilities, to the rest of humanity and the all that makes up the world as we know it.

The P versus NP problem is a major unsolved problem in computer science. Informally, it asks whether every problem whose solution can be quickly verified by a computer can also be quickly solved by a computer. For a correct solution of the “P versus NP” question, the Clay Mathematics Institute (CMI) will award a prize of $1.000.000.

In the mid 1970’s I heard a bureaucrat [Bob Lansdowne] argue that social change came from shifts in compassion or compulsion-he was discussing our relationship with Indonesia and argued that compassion was in short supply. He was suggesting that huge disparities in income and wealth in an increasingly open and global environment were a recipe for instability and conflict–and that we should be afraid of the consequences of failing to address it. His concern is even more relevant today.

I am unable to think of a more difficult question.

Public discourse on politically contested matters—like climate change, refugees, distribution of resources, etc.—seems to be at a low ebb. We need to find ways to address these issues constructively if we are to have any hope of meeting the challenges of the coming years. But how can we be a part of the solution and not just a part of the problem?

Because not only does all the noise drive me mad (I am currently living across the road from a new building site) but constant, irritating noise can affect peoples health. e.g. leaf blowers make we want to commit murder and that would be very unhealthy for at least two of us!

I’m asking because it is a question, after standstill discussions with peers — some for; some against — I cannot clarify to myself what I believe. To have this question answered would not only put my mind at ease, but influence how I see the world and go about my life.

Because climate change is talked about hundreds of times a day and the meaning of the term and issues tat need to be talked about are at odds. It is simply incorrect use of the english language, in a similar way to the use of ‘cement’ when referring to ‘concrete’!
