“The world is running out of chocolate. That’s because climate change and crippling poverty are driving Africa’s cocoa farmers to produce other crops. … In the next 40 years, the temperature in Ghana and Cote d’Ivoire, where 70% of cocoa is grown, is set to rise by 2C. That’s going to make it too hot and dry for cocoa trees.” (http://www.theguardian.com/environment/2015/jun/09/no-beer-chocolate-coffee-how-climate-change-ruin-your-weekend)
Climate Change will require serious adaptation. Cocoa plants need 20-30C, humidity and some shade. I am prepared to share my bath.
Meanwhile, though who knows for how long, fair trade and organic chocolate is available from Ethical Superstore.
