Physical Challenges

The Issues

Let's be clear about the nature of the physical challenges we face.

  • The Earth:
    • Global Climate Change
    • Pollution - both chemicals and plastics
    • Fresh water - increasing demand and decreasing supply
  • The Biosphere:
    • Loss of biodiversity
    • Mass extinction - both species and genera
    • Ocean warming and acidification, leading (amongst other things) to the death of vital coral reefs.
    • Species migration - including human migration
    • Antibiotic resistance
    • Loss of topsoil
  • The Human Race

There is a short (under 20 minutes) video by Economics Explained which summarizes many of these issues: MIT Has Predicted that Society Will Collapse in 2040.

The Solutions

These proposals to address the physical world problems are (to a first approximation anyway) all necessary. We can't just pick one and think we have 'done our bit' - we have to do all of them, or the world as we know it does not survive.

 About antibiotic resistance: Study shows small animals use 'stolen' genes from bacteria to protect against infection.
