Document Summary
Overview: the exploraion of space, including developing life-support systems for humans in space capsules, and photographic images of earth as a blue bubble loaing in space, spawned the concept of spaceship earth . This concept recognized that although earth seems large to us as individual humans, it is inite, with inite amounts of land, air, water, food energy, and other resources to support humans and other life. Requirements are increased by heat, physical exerion, lactaion, and diarrhea. Water quality: if you use water botle you reill, there is a health issue. Repeated handling of botle can out pathogens such as bacteria into the botle. Meat producion uses more water per unit of nutriional value than producion of vegetables, legumes, or cereals. A thick layer of gas forms an atmosphere that surrounds our planet. Humans breath in and out an average of about 10 imes a minute at rest, and more frequently during heavy exerion.
