Different viruses attack different parts of the body - some may attack the skin, others the lungs, and so on. The common cold is also caused by a virus. HIV is not just harmful, it is deadly & dangerous because it attacks the immune system itself, the whole lot that normally gets rid of a virus. It particularly attacks a special type of immune-system cell - without which, the immune system's ability to fight off the virus gets weakened, thus, spreading HIV throughout the body. This entire process is invisible, and there is not other way to let know, just by looking at someone, whether that person is infected by HIV or not, but for a blood test that can detect the presence of this virus in the blood, from about three months after the occurrence of this infection for the very first time. People infected with HIV may look & feel perfectly healthy and it is likely that they may not even know that they are infected. Gradually, the person's immune system weakens with the passage of time and they become increasingly vulnerable to diseases & illnesses, many of which could normally fight off easily otherwise.
The word 'environment' become a catch-all that has driven social, economic and ecological agendas of world at all levels of governance: from global to local to individual.& group Its ascendancy to the top of developmental agendas has also been symptomatic of the industrial age and its impacts/consequences on the global environment due to uncontrolled development - resources consumed and wastes generated.but need lot of utilization
