pre- and post-extinction. Surprisingly, the Mississippian was more “abiotically stable.” This in turn showed no correlation with many abiotic models, but showed a negative correlation with one oxygen model and a positive correlation with one temperature model. Following these findings, the models above were fit with stasis, active trend, and random walk models. Once fitted, it became apparent that biotic factors played the crucial role in selection for body…
the human population and what cause it. The two revolution she attributed to it was the agricultural and industrial revolution, where there is no doubt it increased the population.

P X (1+r) ^ n, P = population = 12.628 billion (2048), r = growth rate = 1.6%, (12.628) X (1 + 0.016) ^ 45 = (12.628) (1.016) ^45 = (12.628)(2.0428) = 25.7964784 =26 billion So, the world’s population would be 25.256 or 26 billion in 2093. “2. With a world population in 2003 of 6.314 billion and a projected population growth rate of 1.1% instead (which is the United Nations’ projection for the period 2003 to 2015).” (Macroeconomics Principles…

is expected to expand to over 10 billion people by the time our generation has begun to reproduce. A way that we as society can produce more with the highly decreasing amount of agricultural land due to manufacturing, infrastructure and population growth is to use our technology and adapt to genetically modified crops for the purpose of higher yields. Those who oppose the use of genetically modified organisms in agriculture do have some credibility when making their case. We have not had the…
