Video conferencing has made it possible to see the picture of the person one is talking with. Great improvement has been done in the field of war science. A country is using ultra modern and super powerful energy and technology. Soldiers sitting on their homeland can win the war. They need not go to the battlefield in person. People have successfully visited the moon and sent missions to the mars. Now they are thinking of the possibility of living in the moon.

The world has achieved a great commercial advancement. Globalisation has made possible free access of products and goods. But, in the crowd of foreign products our local products are facing sad ending. The question of the existence of the poor people has risen. Darwin's theory of survival of the fittest is applicable in this era. One not fittest may not survive. This has many other bad sides also.

The poor countries are lagging behind. They can not exist in the competitive world market. Consequently, they are getting poorer day by day. Privatisation is another trend in this era of globalisation. Governments that have failed in the proper maintenance of mills and factories must ditch those now. Huge lay-off has been resulted by this globalisation centric government policy.

Huge industrial development has taken place after the industrial revolutions in England. Developed countries are polluting the environment of the world. They are using the poorer countries as the dumping grounds of reconditioned materials and industrial wastes. Japan has little agricultural product. But through industrial development, it has reached a leading position in the world.

While this goes on, war becomes a commonplace in this century. One country is against another. In the present situation, might is considered as the right. Devastating weapons are used against mankind. Recently we have seen an example of this. Iraq has almost become a desert. America used innumerable arms and ammunition against the hapless people of Iraq. Political polarisation, mutual misunderstanding, differences in caste, colour, sex, religion and ethnicity are dividing the world. Friendship, trust and understanding are absent among the countries.

Cancer, AIDS, SARS and many other diseases are yet to be cured by medicine. Medical science has to be improved to such an extent that people will not die for want of medication. These are the challenges of this century. Poverty, hunger and war have to be removed from this world. Developed countries should take proper measures to uproot these crises. Still now many people die from malnutrition and curable diseases.

It kindles hope that many countries are adopting democratic mode of governance. They are rejecting monarchy, socialism or communism. Through economic development, the world scenario is going to be changed very soon. As I have already told that mechanical advancement has radically changed human life and activity, people are getting accustomed to doing everything through machines. Modern office can not be imagined without computer.

Time has come to realise and upgrade the standard of living of the people of the world by freeing the mankind from hunger, poverty and malnutrition. These are the challenges of this century. The earlier we ponder over this, the faster we will be able to cope up with the challenges we face.
