The raw materials dilemma: Europe, China, and the Green Deal

Europe wants to encourage economic growth, while also saving our planet from climate collapse. The name of the plan to do this is the "Green Deal.” Under the Green Deal, electric cars are supposed to replace combustion engines, and renewable energies will be used instead of coal, oil, and gas. But green technologies require many critical raw materials, like lithium and rare earths. But these raw materials are rarely mined in Europe anymore. Currently, they come from faraway places like Africa, South America, Russia, and above all, China.

The dark side of AI- Exploitation of humans and nature

While tech companies promise us a better future, AI is already causing serious harm. Huge data centers and server farms are required for AI programs to function. These are paving over landscapes and consuming immense amounts of water and electricity — mostly from fossil fuels, and thus dirty energy sources. Millions of low-wage workers worldwide are busy feeding data to, and training, the algorithms for AI programs — often at the expense of their mental and emotional health. These workers, many of them young and living in the Global South, are exposed to all manner of harmful content to train AI models to detect such material.

Its vast mineral resources - ranging from oil and gas to gold and rare earths, which are indispensable for the energy transition and the defense industry - are turning the island into a new El Dorado. Mining companies and world powers alike are competing for a share.
