My comment relates to population densities and ratio to infrastructure

We have seen development outpacing infrastructure to the detriment of health, safety and the environment. Typical examples include pumping of raw sewage into Chichester harbour , onto beaches, into rivers and waterways. The cause is lack of infrastructure planning which has ruined the fishing, and tourist industry as harbours and coastlines become more and more contaminated with dangerous pathogens. There has been over-extraction of water from chalk streams and rivers. Water utilities are just one example of inverted thinking. There are problems with other major utilities and the provision of health services and education; historically planned as afterthoughts to development, leading to shortages of capacity and high cost of solution and repairs. The over-reliance on cars because of absence of safe cycle paths is another example. So my advice for the next 15 years is Infrastructure First then housing but not until we are ready.
