Resources and Human Impact: Population Growth, Technology, and the Environment

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object, co-developed between NOAA and NSTA, is the second of four Science Objects in the Resources and Human Impact SciPack. It explores how technology can solve problems, but at the same time, can also create new strains on the environment. Improved technology used for harvesting food, coupled with the technology of improved sanitation, has accelerated the growth of the human population. A larger human population increases the impact on the environment and its resources, many of which are limited and non renewable. Due to the rapid growth of the human population and their use of technology in many parts of the world, humans have exceeded the carrying capacity of their environment, compromising human health.
