Space exploration is much too expensive
Space exploration is much too expensive, and the money should be spent on more important things. What is your opinion?

Solution
There is an argument that exploring space is a waste of money and that there are more urgent needs to be addressed on the Earth, such as reducing poverty and preventing environmental destruction. However, I completely disagree with this opinion for two reasons as discussed in further sections.
First of all, many of the technologies we take for granted today were originated due to space research. Take satellite technology, for example, which we depend on for broadcasting and weather forecasting. Without satellites, we would not be able to follow global events as they happen, nor give populations any warning of approaching storms. Space research has also led to the development of new lightweight materials that offer us heat protection and enable food preservation. Therefore, the challenge of sending human beings into space has often driven the development of new technologies that benefit our everyday lives.
Secondly, we cannot foresee the distant future, so we ought to develop the capability to escape from the Earth. Gradually, we are learning how humans can survive for long periods in space and even travel to other planets in the future. If space exploration is halted, this valuable knowledge will never be acquired. Indeed, environmental destruction is also a severe issue, but it is also true that we remain dependent on our environment if we never accept the challenge of exploring other worlds.
Conclusion
In conclusion, while we undoubtedly face serious problems on our own planet, we must continue to explore space. It will promote further technological advances which may prove a blessing for the entire human being. I will say all nations should cooperate in the advancement of space research.
