This story publicises  Sunlight and Seaweed: An Argument for How to Feed, Power and Clean Up the World by Tim Flannery, published by Text Publishing, describing how large offshore rafts, 1km or so square, buoyed 25m below sea surface, can be used to tether ropes, to create healthy new environments growing plant material, giant kelp, seagrass and others, to support growth of shellfish and fish. Kelp can grow as much as 600mm per day, absorbing at least 10 times more CO2 than rainforest, also reducing acidity in seawater to improve conditions for marine life.

Forests more valuable standing than cleared. US economists have found how to subsidise protecting African forests at the village level.
Economists have just shown that, at least sometimes, money does grow on the trees of African forests. By paying villagers in Uganda quite small sums not to clear the forest on their land, they changed collective behaviour and more than halved the expected tree loss. And they demonstrated that the rewards of preserving forest were in cash terms more than 2.4 times greater than the monetary cost of saving the woodland, according to a new study in the journal Science. 

So what will it take to prevent Barnaby Joyce and fellow vandals from resumption of land clearing, back up to 40 footy fields per day?

How about this for innovation and entrepreneurship? In Dubai already, cops can safely and comfortably stay driving a desk, while driverless cop cars cover the beat, continuously gathering video, performing face and rego plate recognition. Inevitably, these things aren’t designed for high speed pursuit but  each car is teamed with a drone which can track at high speed so intercept can be organised.
