People focus their environmental efforts on highly visible but low-impact items like plastic bags and recycling. The climate and environmental impact of the food products they purchase—particularly meat—is orders of magnitude greater. This reveals a massive misallocation of public concern and effort.

While economists favor taxing externalities (e.g., a carbon tax on meat), this approach is often politically impossible. A more effective strategy is developing a technologically superior and cheaper alternative that wins in the free market, making the old, harmful product obsolete.

Citing a Harvard Business School study of 1,800 companies, Sir Ronald Cohen reveals the staggering scale of negative externalities. A third of these firms (600) cause environmental damage equivalent to a quarter or more of their profits, while 250 create more damage than they make in profit, highlighting the financial materiality of impact.

The model of pressuring tech companies to go green doesn't apply to major industrial emitters like oil and steel. For them, the cost of eliminating emissions can be several times their annual profit, a cost no shareholder base would voluntarily accept.

Over the past 50 years, Americans have reduced per capita beef consumption by a third by substituting it with chicken. This seemingly simple dietary shift has inadvertently cut more emissions than any other climate action before the rise of solar power, highlighting the massive climate leverage in reducing beef production and its associated land use.

From credit issuers to project developers and corporate buyers, every party in the carbon credit system benefits from lax standards. This creates a market where most credits likely represent no actual, additional emissions reduction.

The production of one hamburger requires energy and generates emissions equivalent to 5,000-10,000 AI chatbot interactions. This comparison highlights how dietary choices vastly outweigh digital habits in one's personal environmental impact.

Food waste isn't just inefficient; it's a major contributor to climate change. When food scraps decompose in landfills, they release methane, a greenhouse gas 25 times more potent than carbon dioxide. Simple actions like composting can have a significant environmental impact.

Beyond traditional economic factors, climate change creates persistent inflationary pressure. Its impact on harvests drives up food and commodity prices, while increased natural disasters raise insurance and reinsurance rates. This is a crucial, often overlooked, long-term factor in macro analysis.
