A new economy?

I would like Cornwall to be less reliant on tourism. Each year our population triples from half a million to one and a half million! and this puts pressure on our roads, health services, water supply, environment, police forces and supermarkets. I feel that the tourist industry has grown out of control. We need a new economy which is more self sufficient and sustainable. I think that tourism has a place and people have the right to visit other places in the world. But too much tourism can be damaging to the environment and it's local resources. It can also increase the spread of infectious diseases by encouraging travelling at a time which not only endangers lives, but also harms the travel & hospitality industries and other businesses due to the risk of lock downs. We need to be more self sufficient and environmentally friendly. We have Cornish lithium which would provide electric storage batteries for national grid and also lithium ion batteries for electric cars in a new green economy. There is also a lot of potential for wave and geothermal energy for renewable heat and power generation. Not only would this offer employment opportunities, it would also provide a source of income -https://www.cornishlithium.com/. I would like to see an increase in food production, remote working and more creative industries in every town, which would increase revenue in more sustainable ways. Some ideas for sustainable creative businesses would be to provide workshops experiences, skills and education in the following areas - the environment, growing your own food, upcycling, baking, workshops on how to make wildlife housing and wildlife friendly gardens, teaching people how to sew and make their own clothing, furnishings, teaching water sports, art, writing, singing, pottery, dance, cookery classes, etc. The list goes on. These business would increase revenue in a more sustainable way by providing experiences which increase more satisfaction than the purchase of homogenised bric-a-brac. These sustainable business would increase customer satisfaction whilst also increasing the cohesiveness of a community and improving it's mental health.
