Question 2: It is said, that diseases are spreading faster due to globalisation and increased movement of people. Justify the statement taking the example of H5N1 virus.
Answer:
The avian flu (Bird flu) is a current and significant issue which involves the global environment as well as the health of millions of people around the world. The H5N1 virus occurs mainly in birds which is highly contagious or harmful among them and can be deadly.
The major global environmental issue which plays important or significant role in the advancement of the avian influenza virus is globalization, i.e. increasing integration of countries. Through globalization, the progression of the H5N1 avian influenza virus occurs by the world at a pace faster than these scientists can anticipate and also technology and research cannot possibly keep up. Globalization will give the H5N1 avian influenza virus an opportunity to travel the various parts of the world without impediment.
Once, it has developed the ability to spread easily from human to human, the major concern becomes the travel of individuals around the world, particularly air travel. Through air travel, an infected individual could infect dozens of people during their movement, those newly infected individuals would in turn, infect dozens more, and so on and so forth.
