Why are some people against space exploration
They think it is a waste of time and money, and that we should feed the world’s poor and find immediate solutions to other problems, such as pollution and fatal diseases.
Because around the world, millions of people are hungry and dying of starvation. We hear on TV that for as little as a dollar a day, a child in Africa can be saved.
Some people argue that we should stop exploring space.

Sample Writing
Everyone gets excited by the news of the most recent space flights, and I too share in people’s sense of awe. However, I cannot understand spending all this money on expensive research and experiments.
Some people argue that the world will be made impossible to live in through pollution. This seems silly. When your house gets dirty, you spend the time and money to clean it up. You don’t move house simply because you need to clean the floor. It makes more sense to use our time and money to take care of our planet, rather than look for a new home.
In closing, it just does not seem a very wise investment to go to space, since we have so many needs here on the earth to meet.

Conclusion
Ever since space research began, it has been criticized as a huge waste of money and other resources. In my opinion, despite the disadvantages and potential dangers, the advantages are far greater.
Exploring space has already made a difference in the fight against world hunger. The scientists have discovered a new agricultural model, Space Farm, to grow crops, which can improve the output and quality of crops. What’s more, sending astronauts into space has helped people to think about the world’s current problems and even to find ways to solve them.
In closing, exploring space contributes not only to the improvement of quality of human life, but also to our understanding of all the creatures.

Do you know it’s hard to hear in the space
Stardust is silent.
But the every step we take sounded in the universe.
The sound you make can be heard in space.
