Practical ApplicationsThe principles of population ecology can guide us toward resource management goals, like increasing populations we would want to save from extinction, such as polar bears. Some scientists like to use a sustainable resource management, a technique used to sustain any resource for as long as possible. This means maintaining a high population growth rate to keep the population large.

Reducing the population size can be a challenging task. Killing many individuals will not often decrease the population size. Many weeds and insects have a life history traits that are r- selected and can adapt to rapid population growth. Prey species often have higher reproduction rates than their predators, meaning they can rapidly rebound before their predators can.

There are many factors that can influence a population size. We must identify the variables, identify the ther interactions with species, and with the economical, political, and conservation issues correctly manage a population. These same issues can be applied to the human population growth.
