Thomas Malthus’s An Essay on the Principle of Population, a cornerstone of classical economics, presented a grim vision of resource scarcity. This influential work deeply affected Charles Darwin, the father of evolution. Natural selection, Darwin’s core concept, directly reflects Malthus’s ideas about population pressures. The Galapagos Islands‘ finches, for example, provided Darwin with real-world evidence […]
The Chang Jiang (Yangtze) River, a vital waterway for China, faces significant environmental challenges. Industrial activities along the river contribute substantially to the causes of pollution in the Chang Jiang River. Agricultural runoff, specifically fertilizers, is a major contributor to eutrophication in the river’s ecosystem. Furthermore, the impact of the Three Gorges Dam on sediment
