Singapore: Organic Farming.

News article from wildsingapore news - Natural growth: Organic Farming in Singapore

Paragraph taken from the article (which probably sums up the idea i have):

"What are the benefits of supporting the efforts of these local farms? Well, aside from the fact that vegetables tended by Mother Nature are known for their flavour and for being healthier because they are untainted by chemicals, buying local organic produce means that less energy is spent delivering it to the customer.
Notes Mrs Eng-Lim: 'Organic is not just about growing healthy vegetables without pesticides and chemicals; it's also about reducing pollution while farming."


"Perhaps more realistically, the key to getting people to turn over a new (pesticide-free) leaf when they go grocery shopping - and realise the responsibility that they have to buy food that has been produced using sustainable and environmentally-friendly farming methods - lies in a gradual learning process, reckons chef Chiang."


To sum it up, educating the public works.
