Maslow's Hierarchy of Needs is a system that lists the needs felt by every human being, in order of ease of accomplishment. Our basic survival (physiological) needs (food, water, shelter) are on the bottom. Next up is our safety needs (being able to live without fear of danger), followed by love/belonging needs (the need to have people who you support, and whom support you). After that comes esteem needs (the need to be supportive of your own choices). Finally, at the top of the list is the need for self-actualization. This is the need to feel like your life has significant meaning, and that you have done something for the greater good of humanity. This is a rare need to meet.
Hope that helped! =)
The forensic anthropologists
learn that "Grave 15"
contained the remains of numerous women and children from the Guatemalan
massacre during the height of Guatemala’s civil war. Due to their clothing and
jewelry, their ancestry was traced and that they came from Río Negro. The
forensic team uses DNA to identify each skeleton and return them to their
families.
Part 1;
Because there is only limited amounts of fresh water on the Earth the rest is salt water; which humans can not survive on as the salt dehydrates our bodies instead of hydrates.
1) The more we try to get the the fresh water the more we will likely make more pollution.
2) The more we use the less there is.
3) Everything needs water.
Part 2; no idea I believe it is the ice caps, as it is fresh water in the ice caps and not a lot of humans up there to pollute the runoff.
