C) species preservation and use of biocides as the human population grows, common minerals become more scarce. By the early 1800's, the human population that occupied the planet was roughly around 1 billion than doubled to 2 billion by the 1930's with the discovery of mass production. Population growth was a concern as far back as 1798, when English economist Thomas Malthus predicted that it would eventually reduce overall living standards. Public health policy through 2021 forced city-goers to reconsider the modern urban lifestyle. B. The World Resources Institute predicts demand for food will have grown by more than 50 per cent by the time the global population hits close to 10 billion by 2050 by its calculations, with much of the growth happening in the developing countries of Asia and Africa. Rather than simply forecasting future population levels based on the then-current growth rate, the authors helpfully discussed the factors and feedbacks that lead to either population growth or decline. Which of the following is the best way to address this problem? Carrying Capacity Examples. C. Build more and larger-sized landfills.
