Pollinators in decline around the world – ‘Pollinating species will become extinct and we will lose key, irreplaceable species in our ecosystems’

By Matt Walker4 March 2015 (BBC News) – Around the world, animals that pollinate flowering plants are in decline.

In a high-carbon dioxide world, canopy damage from insects limits forest growth – ‘This is the first time, at this scale, that insects have been shown to compromise the ability of forests to take up carbon dioxide’

By Kelly April Tyrrell2 March 2015 (UW-Madison News) – In a high carbon dioxide world, the trees would come out ahead. Except for the munching bugs.
