Carbon emissions from Sportswear

 The most used fabrics in that specific category are Cotton, Polyester, Spandex, Nylon.  Cotton needs gigantic amounts of water to be usable (10,000 liters for 1 kilogram of cotton). In addition, that resource is often harvested with fertilisers destructing biodiversity and causing sanitarian crisis in rural regions such as Central Asia. Polyester, Spandex and Nylon are synthetic fabrics derived from petroleum, as we all know, causing large amounts of carbon emissions or harming biodiversity. Those chemical innovations release microfibres which cannot be treated by recycling plants who release them into the sea with dire consequences on the marine environment. Sneakers are mainly made of petroleum-derived fabrics (Polyester, thermoplastic polyurethane (TPU), polyethylene terephthalate (PET) and ethylene-vinyl acetate (EVA) ) which are the heaviest carbon emitting materials in fashion today. As a result the shoe market in 2020 was responsible of 1% of global carbon emission, an...

what it means to live with covid? Here to stay?

  Nature : Example:   lockdown policy in Singapore vs new cases in united kingdom   Endemic: The technical definition implies a relatively stable rate of transmission in a defined geographic area, without huge waves ripping through the population. It exists in the population at some level, it fluctuates, but it eventually settles where it’s going to settle. But endemic doesn’t reflect severity, said Uphsur, of the U of T. “Hundreds of thousands of children die from malaria every year. That has been a stable phenomenon over time.” Tuberculosis, endemic in many places, also kills huge numbers.  Svalbard, Norway: “Even though the pandemic is not over, and the health preparedness on Svalbard is still vulnerable, the risk that covid-19 infection will lead to a critical load on the health preparedness on the island is considerably less now than before during the pandemic. Therefore, we can make these changes now, which will be positive for the Svalbard community and the l...
