Summarize variations in climate among three major zones as you travel south from the equator forward the south pole?

Hi there,

Equatorial zone: Receives the most sunlight annually, and is constantly warm and humid due to the increased evaporation rates.

Mid Equator/Polar zone: Has a more milder climate with cooler temperatures, as well as progressively less humidity as you further south.

South pole zone: Has a very dry climate with cold temperatures, due to significantly less evaporation and frozen ice.

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
