Question

Liquid water is the most extraordinary substance. We drink it, wash, fish and swim in it, and cook with it. However, we nearly always overlook the special relationship it has with our lives. Discuss some of the impact the presence or absence of water can have on our lives.

Answer 1

pros: keeps us healthy, grows most of our food, keeps the soil enriched to grow food, probably the most natural healthiest thing we can consume, use it to clean, cook....

w/o it: drought, death, famine, increase in deserts/wastelands, deficiencies in the body.....

theres more jus cant think of any more...:)

Answer 2

When water freezes, it forms a surface allowing us to walk on it. thats a unique property of water that allows us to uh... go ice fishing. The human body is also 60-70% water and most humans cant go 3 days without water (as opposed to 3 weeks without food) so its pretty darn important.

Answer 3

Ummm... I suspect the teacher is looking for an answer relevant to the class he/she is teaching, otherwise it is an incredibly stupid question that would take way way way too long to answer.

So, what class is this for?
