India is bringing the population control bill, but its no way going to save us from the apocalypse. To understand the intensity of danger, let us understand the population growth curves. Changes in Population Size: A population will increase in size with every birth and it will decrease in size with every death. Change in population Size = Births (B) - Deaths(D) Mathematical notation: Where N represents the population size, t represents time and ΔN is the change in population size and Δt is the time interval. r Δt is per capita change in population size If, for example, a population of 1,000 individuals increases by 15 individuals per year, then per capita change in population size is 15/1000 or 0.015. If we make the change at each instant in time, the formula changes to: r represents the per capita change in population size that occurs at each instant in time. Exponential Growth: When the population has abundant food and resources and are free to reproduce, they show exponential grow...

Growth of the bacteria refers to an increase in bacterial numbers When bacteria is grown in a liquid nutrient medium, the population is counted at many time intervals, and we get a bacterial growth curve that represents growth of cells over time. Why bacterial growth curve is so important? It gives the idea to learn about the impact of competition in the simplest way. It gives the answer what happens to a population when resources are limited. Bacterial growth best suits even to describe the human population. In science, there are 4 phases, but for simplistic understanding, without any scientific jargon it can be three stages: Thrive, Survive, and Deteriorate Image from wikipedia (A: Lag phase, B: Log phase, C: Stationary phase, D: Death phase) Stage 1: Thrive In this phase bacteria has sufficient resources, so bacteria flourish, prosper or grow vigorously. In science, it's the lag phase and log phase. In the lag phase, there is no cell division, but cells are not dormant, they und...
