explorations have revolutionised our world since
decades. As Yuri Gagarin stepped on the moon, humans_ lifestyles have changed far considerably. From my view, the benefits humans earned from
section can be greater than the minimal drawbacks.
On the one hand, investment
projects is less important than other problems humans have. The
of the poor people. Each year, billions of dollars are considered by plenty of developed countries for
money can be used in
parts, including farming.
, in Africa, thousands of people die because of the shortage of food annually;
, had the US government assisted these nations, more humans would have survived.
of focusing on the
voyage, international organisations must have
of humans in the Middle East lose their home and have to leave their country. As a prime example, recently hundreds of thousands of People in Syria fled to Europe, whereas never sending a spacecraft to Mars can be useful to protect them.
, humanity has more important issues which must be solved than sending the man to the moon.
, I think the benefits gained by
travelling can be far considerable than its marginal drawbacks. The
reason behind it is that it has led other technologies to develop more. Definitely, had not scientists used
navigation technologies in aircraft, passengers would not have reached their destination so fast.
, the materials used in the body of new planes are copied from Shuttle, increasing their speed and having more efficient fuel consumption.
, it will help humans to find another planet for living. Obviously, knowing more about
and other planets will assist scientists to find another option except for Earth because we cannot predict how long our plant will be alive. For
reason, recently scientists
NASA are to send some volunteers to Mars to find out more about its environment and probable choice for living of humans in the future. Without having a thoughtful plan other generations_ safety might become more at risk
some unpredictable natural accidents destroying our globe.
To sum up,
exploration might be useless compared with other important problem nations have, its benefits should not be forgotten. I personally believe that it has led humans to live in a more modern world, and a safer alternative planet might be found by
