Earth problems / Space exploration. Сочинение C2 (английский язык) в формате ЕГЭ-2014
It is said that many countries spend lots of money on space exploration. Some people think that it is a right way; others believe that there is a better way to use the money.

The question of exploring space has been discussed from the very beginning of space exploration. Some people say that it is our future, whereas others are quite skeptical.
I think that we should definitely explore space and spend as much money as required. First of all, our planet cannot exist forever. One day it will end and humans will have to move somewhere to continue living. Second, underground resources are finite and they will eventually end. It would be nice to have a possibility to import raw materials from other planets. It is also very interesting to meet other civilizations, if they exist.
At the same time, there are people who think that exploring space is a big waste of time and money. Every space shot costs us a lot of money. It is better to do something on earth that can be useful here and now.
In my opinion, it is not really a good forward-looking policy. It is better to be prepared for possible troubles that can come faster than we think. Global Warming can submerge the entire planet or a comet can hit the earth. I think people should be ready for any possible danger.
In conclusion, I would like to say it is difficult to keep doing space exploration when our national economic situation is not that good. Nevertheless, we should keep investing into space exploration because I strongly believe that one day it will bring the desired results. Thus, I support the idea that space exploration is worth doing.
In conclusion, I would like to say there are opposing views on this issue. At first sight space exploration is a big waste of time and money but in actual fact it can bring a lot of benefit to people. Thus, I strongly believe that exploring space is worth doing.

At the time of the landing on the moon in 1969, many sincerely believed, that by the beginning of the 21st century space travel became commonplace and the earthlings began to flee quietly to other planets. Unfortunately, it is not yet arrived, and people began to doubt whether they really need these space travel. Maybe the moon is enough? Nevertheless, space exploration gives us invaluable information in the fields of medicine, mining and security. And, of course, progress in the study of outer space has an inspiring effect on humanity!
Protection against possible collision with an asteroid is one of the most important reason to discover space. If we do not want to end like dinosaurs, we need to protect ourselves from the threat of collision with a large asteroid. As a rule, about once in 10 thousand years, some heavenly body the size of a football field threatens to land in the Earth, which can lead to irreversible consequences for the planet. We really should be afraid of such «guests» with a minimum diameter of 100 meters. The collision will raise a dust storm, destroy forests and fields, and doom to death those who survive. Special space programs are aimed at establishing a dangerous object long before it approaches the Earth, and knock it off the trajectory of motion.
Secondly, contribution to medicine and health care. The development of space has led to the emergence of many medical innovations for terrestrial use: for example, the method of introducing anticancer drugs directly into the tumor, the equipment by which a nurse can do ultrasound and instantly transfer data to a physician thousands of miles away, and a mechanical manipulator arm performing complex actions inside the MRI. Pharmaceutical development in the field of protection of astronauts from loss of bone and muscle mass in microgravity conditions led to the creation of drugs for the prevention and treatment of osteoporosis. And these drugs were easier to test in space, because astronauts lose about 1.5% of bone mass per month, and the elderly terrestrial woman loses 1.5% per year.
Space exploration inspires humanity to new achievements.
If we want to create a world in which our children will strive to become scientists and engineers, not leading reality shows, movie stars or financial magnates, then space exploration is a very inspiring process. It’s time to ask the growing generation the question: «Who wants to be an aerospace engineer and design an aircraft that can get into the dilapidated atmosphere of Mars?»
Do not forget that we need raw materials from outer space. There is gold, silver, platinum and other valuable metals. Some international companies are already thinking about extracting minerals on asteroids, so it is possible that the profession of a space miner will appear in the near future. The moon, for example, is a possible «supplier» of helium-3 (used for MRI and is considered as a possible fuel for nuclear power plants). On Earth, this substance costs up to 5 thousand dollars per liter. The moon is also considered a potential source of rare earth elements, such as europium and tantalum, which are in high demand for use in electronics, solar cell production and other advanced devices.
Space exploration can help to find the answer to a very important question. We all believe that somewhere in space there is life. In addition, many believe that aliens have already visited our planet. However, we still have not received any signals from distant civilizations. That is why the scientists-seekers of extraterrestrial civilizations are ready to deploy orbital observatories, for example, the James Webb space telescope. This satellite is planned to be launched in 2018, and with its help, it will be possible to search for life in the atmospheres of distant planets outside our solar system by chemical characteristics. Moreover, this is only the beginning.
For its survival, humanity will probably have to colonize outer space. We learned how to send satellites into space, and this helps us control and deal with pressing earthly problems, including forest fires, oil spills and depletion of aquifers. However, a significant increase in the number of people, banal greed and unjustified frivolity regarding environmental consequences have already caused serious damage to our planet. Scientists believe that the Earth has an «allowable load» in the amount of 8 to 16 billion, and we have more than 7 billion. Perhaps it is time for humankind to prepare for the development of other planets for life.

global problems on Earth (essay)
It is reported that billions of dollars are spent on
space exploration projects every year. Some people believe that this money
should be used to solve problems on Earth.
Why do people learn space? In my opinion the first
cause is human’s curiosity, the second is fear, fear of the planet’s death.
People recognize that they destroy their Planet, and they are afraid of
dying with our Earth. Because of it humanity hopes to save itself on any planet
in another galaxy. But in my opinion this way is unreal. We should solve
global earth problems and save our Planet and life on it. Humanity must
overcome crisis appearing between a man and nature. Billions of dollars will
be spent with benefit.
What global problems are existed? The amount of them
is great. Here is the main of them:
Poverty, food problems, energy problems, environmental
problems, demographic problems and the researching of the World Ocean.
People know if these problems are not disappear,
the Earth will die. But why many of them want to do nothing? They hope that
these problems will disappear themselves. Though, such inactivity is better
than active destroying of nature, pollution of bodies of water, deforestation,
killing of animals, especially of seldom creatures.
It is impossible to understand behaviour of these
people. They should think that their children and grandchildren will have to
live on the dying Planet, if the life itself will be possible.
We can’t hope that somebody will get rid us of
global problems at once. Global problems of humanity can be solved only together,
if all humanity makes efforts.
You shouldn’t think that one person isn’t able to cope
with world problems, because of it, it seems that to act is useless, thoughts
about weakness in front of difficulties appear . The meaning is to unite
efforts and to help to prosper your own town at any rate, to solve problems of
your little place of living being.
And when each person on the Earth will be responsible
to himself and his country, global problems will be solved, and we won’t find
rescue in space and spend so much money on space researches.
