Green New Deal
I would echo much of what has already been said (reduce traffic, fewer second homes, diversify from our reliance on tourist industry, definitely facilitate/encourage safe cycling) but on top of that we need to make climate change the number one consideration in an decision-making.
Let's think radically! Reduce traffic by making public transport convenient, frequent and free at point of use (paid by taxes - if public transport was an easy option, we wouldn't need our cars so would save us money bearing in mind most cars are stationary for 95% of the time). Encourage cycling (and walking) with safe cycle lanes - this would make us healthier and save NHS costs.
Encourage localism - food production, shopping, energy - to make our towns more resilient in the face of an uncertain future.
Invest! Stop the nonsense of millions of pounds spent on a 'spaceport' (ie expansion of Newquay Airport, a massive waste of taxpayers' money going into the pocket of billionaire Richard Branson to provide, at the last estimate, a total of 3 local jobs) and instead think of making Cornwall a leader in renewable energy, public transport, affordable carbon neutral housing and all the jobs this investment could provide.
I applaud this consultation exercise - how great would it be to see it extended to a Citizen's Assembly for Cornwall?
