"This book describes the public health system in broad strokes in order to focus the reader on basic public health goals, principles, structures, and practices. The context in which public health is practiced today has changed considerably since its historic roots in the Industrial Revolution of the 18th and 19th centuries. As a result, public health practices are changed and changing still. However, the overarching goal of public health systems remains the same-to ensure through collective action a healthful environment for all. The 21st century offers incredible challenges to public health. The disparity in access to healthy environments is widening, and the threats to health concern the foundations of health, including adequate and nutritious food, clean and sufficient water, and shelter. Moreover, these are global problems that touch every country to some extent and threaten to affect all countries within our lifetimes. This fact was made particularly clear by the COVID-19 pandemic."
Abstract In recent years, food insecurity has worsened despite decades of progress. Agrifood systems must evolve to address population expansion and climate change simultaneously. A problem of this magnitude necessitates the development of technologies that simultaneously increase (nutritious) food production and protect the environment. Based on an a diagram analysis of the economic model of technological change, this article explores various technological paths that can emerge in response to rising food prices and the need to preserve land. This article indicates, through the use of specialized literature, that the hypotheses derived from the analysis of the technological change model already exist. In addition, we investigate the potential geopolitical effects of these technological shifts on the global agri-food industry. Changes aimed at conserving land must encourage urban food production, systematic resource optimization on abundant high-quality land, and regenerative practices. In addition to rising food prices and population growth, the increasing significance of urban consumers and the internalization of environmental values should drive these various developments.

Much grumbling here: A major Currys investor has hit out at the "absurdity" of valuations on the London Stock Exchange as two more companies prepare to quit.JO Hambro Capital, a top 10 Currys shareholder, criticised the dismal valuations the London stock market attaches to businesses, saying Currys should be worth far more than what investors have valued it at.The electronics retailer is subject to a possible bidding war between suitors Elliott Advisors and China's JD.Com. Currys recently rejected a 67p per share bid from Elliott, which valued the business at about £756m.Hambro's veteran fund managers, James Lowen and Clive Beagles, said an "acceptable offer" for the tech retailer would be closer to 100p per share, which would value the company at close to £1bn. Someone with something to sell complaining about the low price a potential buyer is willing to offer. Ho Hum.As ever, prices in markets are information. We may not like the information on offer but that is the information the real world is supplying us with.Fortunately, the system itself contains the cure to what apparently ails it: The gloom over the London market intensified on Tuesday after one of its oldest constituents was also snapped up by an American buyer for £1bn. Spirent Communications, which has been listed since 1955, agreed to an all-cash takeover by US rival Viavi Group.The British tech company works with companies like Amazon and Meta, testing their equipment. Shares surged 58pc to 172 pence, just below the takeover price.It marks the fourth foreign bid for a London listed company in the last few weeks, following the Currys offers and bids for Wincanton and Direct Line.The cure for low prices is low prices. Potential buyers note low prices, buy, and this pushes up prices. The rest of us need do nothing other than observe. Or, the particularly brave might note the claims of low prices and get in there before the others do. But in terms of the system, rather than our individual reactions to it, nothing need be done. For markets do contain their own stabilisers, high prices are the cure for high prices - encouraging greater supply - and low prices cure low prices, encouraging demand.We're done, sorted.
