How does population affect global warming?and the effect of global warming on land masses?

Question

I want to know how will population cause global warming. so far i have..

Population

1. Planet support 5.6 billion

a.) Food

b.) Clean water

c.) Air

d.) Materials/Natural resources

e.) Medicine

f.) Technology/Entertainment

g.) Energy

h.) Shelter

2. Developing Countries demand more farmland

.... but i want to know more

and how will land masses get affected by global warming? like my example...

B. Land Masses

1. Glaciers and ice sheets meltdown

a.) Sun’s energy hits glaciers

b.) Causes glaciers to melt to water

c.) Sun’s energy hits meltwater

d.) Causes glacier to melt even faster speed

e.) Glaciers disappear in next half century

1.) 2.6 billion of worlds people face drinking/water shortage

2.) Himilayas provide more than half of drinking water and 40% of world’s population

2. Loss of barrier islands and wetlands

but what else land will get affected?

Answer 1

this always reliable for populations, sizes of countries, gdp's etc.;

what else land? lower rainfall in many already dry areas e.g. australia, sub-saharan africa, west china, south west u.s.a., italy, spain.

wilder weather e.g. storms, floods, in other areas e.g. eire, scotland, wales, northern england. sorry dont know about in u.s.

Answer 2

Population can be looked at in many ways. If you consider the population per unit of area its very small-about one person per acre or so. If you look at large cities 20,000 people per square mile is a good mix; so all 10 billion can be healthy on less than 1% of the Earth's surface. The 99% of the Earth not needed by 10 or 20 billion people can be left alone but won't be. Anyway, the point is there is enough for everyone to live well if the systems are developed to let it happen. It seems clear 50 billion people could live very well on the planet without too much stress on it.

Answer 3

the more people the more release of CO2(CARBON DEOXIDE).

Answer 4

global warming is real but is a natural occurrence in the world. it isn't that people started global warming, it's that they speed it up by everything they do. "global warming" is actually just the relatively short times between ice ages

Answer 5

The largest single area of CO2 emissions is Building heating and cooling (More than cars). With less people we would have less buildings.
