Scientists believe that finding other life forms in space by sending messages is a good idea while others think it can be dangerous. Discuss both view and give your opinion.

During the past decades, the public has debated about the transmission of radio waves to seek other creatures outside the earth. Many believe in this method, while others argue we take risks to do so. To my mind, we should reconsider it to avoid potential risks and choose other ways instead.

The experience shows that this approach works inefficiently and has its own limit. Firstly, we have received no responses from extra-terrestrial beings so far. Secondly, only intelligent aliens will respond to us accordingly. Consequently, we will remain ignorant about other terrestrial organisms. By contrast, the cautious opinion sounds more reasonable due to possible perils. One of the dangers could be a widespread pandemic. If unknown intelligent beings visit us, even without malicious intentions, viruses or bacteria accompanying them will cause an unexpected worldwide outbreak of a deadly disease. As a result, human beings could be in danger. Furthermore, their misused technologies will probably destroy our world.

Therefore, I argue that we need to give more considerations about it. Apart from these dangers, we refuse to squander large amounts of money on these projects. Actually, we have already had more effective and useful discovering methods. For example, we have explored other planets by using satellites, rovers and other detection robots. And the information sent back by these machines have continuously enriched our knowledge of other life forms. Astronomical observatories on earth also provide significant reports on possible target planets with living organisms. The more we understand about these alien creatures, the better we prepare against future perils.

In conclusion, we should think twice about the idea of discovering other beings by sending information to the outer space due to potential risks. Rather, we ought to prefer other options.

Correct few errors,

During the past decades, public around the world have debated on whether we should deliver information to seek for outer space creatures. Many believe in such method, while others argue we take risks to do so. To my mind, I suggest we have better ways to make such discoveries.

First and foremost, the transmitting of our messages to the space would give rise to hazards and even potential destruction of our civilization if we fail to take precautions against such peril. To be more specific, an alien culture, which has far advanced technologies and supreme intelligence, might impose an imminent threat to our society. Therefore, more cautious opinion (the second view) is more reasonable. Some of our scientists also suggest that even if this extraordinary world has no malicious intentions, the organisms accompanied with them, virus or bacteria for instance would cause an unexpected pandemic. As a result, human beings could be in danger. In addition, researchers have found that delivering messages has proved to be of no avail and inefficient in that we have to wait for years to receive the responses and the chance is scant.

As is illustrated, I argue that we should abandon such insensible way, rather, we should choose alternative approaches to deepen our understanding of other life patterns in universe. For example, we have explored the moon and Mars by using space crafts and other detection robots, which collect more useful information to us and conduct dozens of experiments for us. Furthermore, there are hundreds of observatory stations around the world, receiving and collecting significant astronomical data from the universe, which sometimes provide exciting reports regarding possible target planets with potential beings. Through these ways, we can have enough knowledge about these aliens to be well prepared proactively before they visit us.

In conclusion, we must reconsider the idea of discovering other creatures by sending information to cosmos due to potential risks. Instead, we should prefer other options.
