Why is democracy the secret for sustainability? Two reasons: 1) it allows the majority of good sensible people to stop the unsustainable ones; 2) its makes sure that people feel they have the ability to make change, because without the ability to make change people see being sustainable as futile and give up - paradoxically ensuring what they hoped to avoid!
The image above is 440-480 million year old fossil Trilobite we found in Wales. Trilobites roamed our oceans for over 270 million years before going extinct - in comparison us humans have existed for less than 200,000 years. Finding these incredible impressions makes you wonder what trace will we leave?
Only certain types of fish, including mackeral and tuna, have dangerous levels of mercury and only if you eat them nearly every day. Though the Atlantic Mackeral caught here in Cornwall, contain a lot less Mercury than the Spanish Mackeral eaten elsewhere and are very safe and healthy to eat.
Biomining also could be cheaper and greener than traditional mining, using less water and emitting less CO2 than conventional crushing, heating and chemical processes. Biomining works at much lower temperatures and pressures than normal techniques reducing the electricity bill and resources used to get the metal out of the rock.
For millions of years shells made of calcium carbonate were all the rage amongst marine life, then a new plucky family known as vertebrates turned marine fashion inside-out by putting skeletons on the inside.
Fritz Haber was a German chemist, who made food from air. He invented the Haber-Bosch process that takes nitrogen from the air and turns it into fertiliser, feeding billions - half the protein in our body is a result of this process. He won a Nobel prize and was Albert Einsteins friend and for a time was one of Germany's heros. However he was also one of the fathers of gas warfare, responsible for countless horrific deaths (including his wife) and is considered a war criminal today.
