<span>AZT and other medications that work as reverse transcriptase inhibitors interfere with DNA replication in HIV/AIDS cells, which prevents reproduction of these cells. Though it does not cure this illness, it does interfere with the rapid mutation cycle which, in turn, decreases the amount of illnesses suffered by the patient. This makes it possible for the patient to survive with this virus/disease longer and remain in a relatively healthy state. Though, as already mentioned, the sufferer is still infected and does need to take the proper precautions to avoid spreading the infection.</span>
The origin of man took place about 200,000 years ago and looking at the records that are stored in the ice cores before the existence of man which were found by the deep drilling of the antarctic and Greenland shows that how the temperatures have changed and as the example of the carbon in the air.
As in the 800,000 years go the Carbon dioxide levels were on average of 170 to 280 ppm and now they have crossed the 400 ppm mark also at that time the sea levels were high as 80 feet and now are more than 100 feet.
