Published on Sep 26, 2011

Teachers have long been pressured to teach “alternate views” of evolution. Now they’re being pushed to deny that global warming is happening, or if it is, that humans aren’t a major factor. Genie Scott dissects the tactics of climate change deniers, and the parallels with anti-evolutionists. Where: Glasgow, Scotland. When September 15, 2011

Naomi Oreskes explains with great clarity the driving force behind climate denial – aversion to the political and economic implications of climate change. UPDATE: Some commenters are asking about evidence that humans are causing global warming.

A summary is provided at http://sks.to/evidence and http://sks.to/agw with links to the many peer-reviewed papers that provide empirical evidence for human caused global warming.

Recycling hope for plastic-hungry enzyme – BBC News

By Mary Halton Science reporter, BBC News

• 16 April 2018

Scientists have improved a naturally occurring enzyme which can digest some of our most commonly polluting plastics.

PET, the strong plastic commonly used in bottles, takes hundreds of years to break down in the environment.

The modified enzyme, known as PETase, can start breaking down the same material in just a few days.

This could revolutionise the recycling process, allowing plastics to be re-used more effectively.

UK consumers use around 13 billion plastic drinks bottles a year but more than three billion are not recycled.

• Five ways to break up with plastic
• Could plant-based plastics help tackle pollution?
• Ocean plastic could triple within a decade

Found in a dump

Originally discovered in Japan, the enzyme is produced by a bacterium which “eats” PET.

Ideonella sakaiensis uses the plastic as its major energy source.

Researchers reported in 2016 that they had found the strain living in sediments at a bottle recycling site in the port city of Sakai.
