Technology, science and us 3.
Scientists have cloned a sheep, a pig and a monkey, and hope to use this method to clone and replace sick organs in humans. People who are unable to have children can have
a tube baby.
Transport has changed completely. At the beginning of the 20 th century most people travelled on foot or by horse-drawn vehicals. Nowadays there is public transport in most towns, high-speed trains and supersonic planes to travel long distances and cars to get to work, to shops or to go for a weekend break.
Then, for example, man has overcome the power of gravity and can launch satellites, rockets, space shuttles, spaceships, space probes, telescopes that either serve communication on Earth or explore the Solar System. A couple of them have already left it. Man has set foot on the Moon and has brought back some moon rocks.
The first man in the space was Jurij Gagarin from Russia in 12.4. 1961 but the first man on the Moon was the American Neal Armstrong in 1969.And now I would like to say something about problems in society. I will start with unemployment that is an economic danger for every country.
