I don't believe that today's wonders are similar in kind to the wonders of the Ancient World. They were all buildings and statues. In the last two, centuries we have, seen unprecedented technical and scientific, achievements, These are surely our modern wonders. Here is my list.
1. Computers
They have already revolutionized the way we live and work. Bat it is early days; for computers. We don't know how much they are still changing world. More computer wonders are yet to come.
2. Space Travel
Only a few years before men were walking on the moon, reputable dentists declared that it was impossible. But in 1969 Neil Armstrong stepped out of his, space capsule and made his famous statement: That's one small step for a man, one giant leap for mankind.
3. Medical Science
Surely nothing has done more for the comfort and happiness of mankind than the advance of medical knowledge! How many millions of people have benefited from the humble aspirin? How many, lives has penicillin saved? Average life expectancy in Europe has risen dramatically over the last hundred years, from about 50 years in 1906 to about 75 years to ay.
4. Holidays
Yes - holidays! In fact there have always been holidays —.in ancient Rome there were more than 150 a year - but a holiday use i to mean simply a day when you didn't work. Now holidaymakers travel to all parts of rue world. Perhaps you don't like so many tourists in your country, but you must agree that a phenomenon which sees the population of Greece treble in summer, and which sends office workers and shop: assistants to Spam, Turkey, or the Caribbean is a wonder of the world.
5. The Olympic Games
It is true that the Olympic Games are now commercialized and there is greed and drug abuse. However, it is a competition in which every country in the world takes part. Every four years, for a brief moment, we see these countries came together in peace and friendship. We feel hope again for the future of mankind.
6. Agriculture
In 1724, Jonathan Swift wrote. Whoever makes two blades of grass or two ears of corn grow where only one grew before serves mankind, better than the whole race of politicians. In Europe our farmers have done this. In 1709 whole villages in France died of hunger. Now, in Europe we can't eat all the food we produce. If only the politicians Could find a way to share it with those parts of the world where there is still famine.
7. We are still here
The last wonder of the modern world is; simply that we are still here. We have bombs that could destroy the world but we have, not used them. This is surely the greatest wonder of all!
