Bleak, freezing, inhospitable: its hard to overstate how harsh Arctic climate is for a near-hairless ape from Africa. Hidden in darkness for half a year and blinded by 24 hour light for the other half - It was one of the last places humans settled. The Vikings who tried to live their failed and to this day few Europeans live there, only the native Inuit peoples have mastered this ice-scape.
The clothing industry accounts for 10% of global CO2 emissions a year – making over 1.2 billion tonnes of CO2 – more emission than all the planes in the world combined. Clothing also consumes thousands of litres of water and tonnes of energy and non-renewable resources, too.
In the past many scientists and economists presumed we were purely rational beings, self-promoting our own interests with perfect knowledge of the consequences of our actions. These assumptions are really influential: many world governments rely on our self-interest and perfect decision-making to change our behaviour, hoping rational arguments and penny-savings will alter our trajectory towards crisis.
A study in 2017, trying to understand why and how microplastics are getting in the marine food chain, found that when coral were offered plastic, sand and bacteria-covered plastic + sand they actually preferred the naked-plastic. They even retained the plastic for longer compared to the other food. They suspect that some types of plastic contain chemicals which stimulate the corals - which are tiny animals related to jellyfish - to feed. Or in other words, plastic is tasty for corals.
Across the planet excess wind and solar power is being gathered and used to pump water uphill into lakes, so that when the wind dies and the sun goes down, the water can run back downhill through hydroelectric generators. This turns lakes into super-batteries capable of storing enough energy to power tens of thousands of homes.
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.
