"Excess release of phosphorus is the main culprit for the eutrophication of freshwater and marine ecosystems [1]. Phosphorus is a nonrenewable and irreplaceable element for plant growth, and its role is crucial in agricultural production [2]. The accelerated growth in food demand has also increased the demand for phosphate fertilizers, which has placed stress on phosphate rock sources and is exhausting existing deposits [3]. The phosphate mining industry is also facing serious challenges regarding water availability for the mining process and a decrease in the quality of phosphate rocks"

"For a snapshot of what all this points to regarding the total materials footprint of the green energy path, consider the supply chain for an electric car battery. A single battery providing a useful driving range weighs about 1,000 pounds.[15] Providing the refined minerals needed to fabricate a single EV battery requires the mining, moving, and processing of more than 500,000 pounds of materials somewhere on the planet (see sidebar below).[16] That's 20 times more than the 25,000 pounds of petroleum that an internal combustion engine uses over the life of a car."

"I have seen one fool's gold rush from up close in the lead up to the 2008 financial crisis. It feels like we may be on the cusp of another with cryptocurrencies (crypto) and decentralized finance (DeFi). The 2008 crisis holds lessons that can help industry and regulators chart a better path and avoid repeating the mistakes of the past."

"The move comes amid a global cryptocurrency crackdown as governments from Asia to the United States fret that privately operated highly volatile digital currencies could undermine their control of the financial and monetary systems, increase systemic risk, promote financial crime and hurt investors."

Facebook is working on a new artificial intelligence (AI)-based system that can analyse your lives through first-person videos, recording what they see, do, and hear to assist you with daily tasks. The system is hoping to solve research challenges in 'egocentric perception' (the perception of direction or position of oneself based on visual information). Facebook AI has developed five benchmark challenges centred on first-person visual experience - episodic memory, forecasting, hand and object manipulation, audio-visual "diarization," and social interaction. On the upside, a robotic assistant could be introduced to a person via a series of videos and be able to provide a personalized presence. I would assume that if the robot could have constant access to first-person videos it could continue to learn. On the downside, even more data mining.
