Reading a fascinating article about work undertaken at Cambridge University adding bio-luminescence to trees.

Apparently just converting 0.02% of the energy absorbed from photosynthesis would be sufficient for a tree to produce bio light in enough quantity to compete with a regular street light.

By 2050 we need to reduce our CO2 use by 80%.

Is bio light one way of achieving this?

Which would you prefer – a genetically modified tree producing light or global warming?
