Mexico City – A public referendum has cancelled Foster + Partners’ new airport for the Mexican capital, which was midway through construction.

Although the airport has been in development since 2015, earlier this year the public started a proposal to cancel the project due to environmental and overspending concerns. The proposal formed a large part of López Obrador's presidential campaign, who, after winning the election, announced a referendum to decide the fate of the airport.

A large majority (70%) of voters opted to scrap the airport, which Obrador has respected. ‘The decision taken by the citizens is democratic, rational and efficient,’ he announced. As an alternative to the costly airport, Obrador has suggested transforming the partially-built construction into a sports and ecological centre to better serve the city.

Brands and governments must recognise the importance of the public in their decision-making processes, and encourage consumers to club together as Collective Stakeholders.

Bangkok – A new product by Givaudan features Darkenyl, a hair re-pigmenting ingredient to counteract the hair whitening process.

Givaudan, the flavour and fragrances manufacturer, has worked with skin experts to develop the ingredient, which combines two synergistic molecules to boost hair stem cells proliferation and protect the hair from ageing. Following a clinical study which found that volunteers had up to -56% reduction of white hair after using Darkenyl, the company has added the ingredient to its S3D Colourblack hair product.

With 59% of consumers worried about hair ageing – with higher numbers in Japan and China – and 60% concerned about hair colour loss, according to the brand, beauty consumers have previously struggled to find products that scientifically reverse white hairs, often resorting to dye.

Although beauty brands have long promoted anti-ageing formulas for the skin, hair ageing is a sensitive issue that is under-addressed by brands.

According to a study by a team of researchers in Hawaii, which was published in the journal Nature Climate Change last week, Bitcoin could push global warming above 2°C in as little as two decades.

The process of ‘mining’ Bitcoin demands substantial energy resources, with heavy hardware requirements. To investigate the timeframe for Bitcoin’s impact on climate change, the researchers compared the projected growth of Bitcoin to the historic uptake of technology such as dishwashers and the internet, in order to determine how pervasive it will become in the near future.

Although cryptocurrencies have seen success in competing with financial institutions, many experts have expressed concerns over their environmental impact. Read our macrotrend Morality Recoded for more on why technology companies must consider future impacts before mindlessly innovating.
