Document Summary

Environmental science - the scienti c study of:: how the natural world works, how the environment affects humans and vice versa ! How it affects your life / your interactions with it : the pursuit of knowledge about the environment and our interactions with it! The earth may seem enormous to us! But earth and its systems are nite and limited! Like buying new jeans this impacts the earth and us ! Environmental relating to the living and nonliving things around us! Environment all the living and nonliving things around us (including people) : non-living, living, together! Describe the steps of the scienti c method and the process of science! Science: a systematic process for learning about the world and testing our understanding of it, the body of knowledge arising from the dynamic process of observation, questioning, testing, and discovery!
