Humanity is facing a number of challenges that are increasing in intensity and are projected to become much worse in the coming years. The era of profligate consumption, aided by developments in science and technology, is causing enormous harm to the ecosystem on which we depend for our welfare, even survival. Our present lifestyle requires excessive amounts of planetary resources and generates numerous pollutants and waste materials. Ignorance of planetary limits and considering Earth to be a limitless source of useful materials and an infinite sink of unwanted products is endangering our future by depleting natural resources and degrading the environment. Many such developments have already begun to adversely affect the ecosystem. This book discusses these issues in a comprehensive manner, including climate change and its deleterious consequences, degradation and pollution of air, land, and seas, changing weather patterns, rising sea levels, forest fires, expanding deserts, and shortage of fresh water in many parts of the world. Each chapter of the book ends with a section with the title “The Way Forward” that makes suggestions for actions to be taken expeditiously to stop the progression of dangerous events. The continuous search for comforts, conveniences, and novel objects has brought humanity to a state where the continuation of this process endangers our welfare. While the effects of climate change will adversely affect our lives in many ways, there are numerous other developments that are detrimental to our way of life. Forests, which play a crucial role in maintaining the integrity of the environment and provide many benefits to humanity, are being razed for immediate gains. Overfishing and pollution are decreasing the productivity of seas. The flow of water in many rivers is decreasing due to overexploitation, irregular weather patterns, and loss of icecaps on mountain peaks. The productivity of farmlands, crucial for our survival, is decreasing due to the loss of topsoil and accumulation of salts. There are many such factors that threaten the welfare of large segments of population. The ultimate cause of these deleterious developments is humanity’s expanding search for novel objects without considering sustainability, and the implicit belief that technological developments will eventually solve all problems created by the culture of overconsumption. While technology can provide us with gizmos with amazing properties, problems of environmental degradation are global problems that require concerted actions by people everywhere. The degradation of the planetary environment and depletion of resources is occurring at a rapid rate. A lack of concern for sustainability while searching for items that provide immediate benefits is degrading the ecosystem. We may pass the planet on to the younger generations with more pollution, irregular weather patterns, and fewer endowments that may seriously limit their lives. Events are moving at such a pace that expeditious actions are required on many fronts.
We have learned not to take food seriously: we eat as much as we want of what we want when we want it, and we seldom think about the health and environmental consequences of our choices. But the fact is that every choice we make has an impact on our health and on the environment. In The Vegetarian Imperative, Anand M. Saxena, a scientist and lifelong vegetarian, explains why we need to make better choices: for better health, to eliminate world hunger, and, ultimately, to save the planet. Our insatiable appetite for animal-based foods contributes directly to high rates of chronic diseases -- resulting in both illness and death. It also leads to a devastating overuse of natural resources that dangerously depletes the food available for human consumption. The burgeoning population and increasing preference for meat in all parts of the world are stretching planetary resources beyond their limits, and the huge livestock industry is degrading the agricultural land and polluting air and water. Continuing at this pace will bring us to the crisis point in just a few decades -- a reality that threatens not only our current lifestyle but our very survival. This book shows us a way out of this dangerous and vicious cycle, recommending a much-needed shift to a diet of properly chosen plant-based foods. Each of these arguments alone -- personal health, worldwide hunger, and environmental degradation -- provides reason enough to stop consuming so much animal-based food; taken together, they make an unassailable case for vegetarianism. Supported by up-to-date and accurate scientific data, The Vegetarian Imperative will make you rethink what you eat -- and help you save the planet.
