Science in Personal and Social Perspectives (9 - 12)Changes in environments
Environments are the space, conditions, and factors that affect an individual's and a population's ability to survive and their quality of life.
Changes in environments can be natural or influenced by humans. Some changes are good, some are bad, and some are neither good nor bad. Pollution is a change in the environment that can influence the health, survival, or activities of organisms, including humans.
Some environmental changes occur slowly, and others occur rapidly. Students should understand the different consequences of changing environments in small increments over long periods as compared with changing environments in large increments over short periods.
