Countries around the globe are spending billions of dollars and lots of time on various space missions, whether to Mars or other planets much further away. Some people argue that we should stop wasting time and money exploring space. Instead, we should feed the world’s poor and find immediate solutions to other problems, such as pollution and fatal diseases. However, others feel this is a shallow view which fails to realise how exploring space helps us.

Firstly, exploring space has already made a difference in the fight against world hunger. It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data on land and weather patterns. Then the data is transmitted to scientists on Earth. After careful analysis, the scientists can provide useful recommendations and advice for farmers. As a result, space-based science has helped farming in its efforts to grow enough food to feed Earth’s increasing population.

Secondly, space exploration has already promoted technological improvements that benefit us all. High-end products around the world are made to a higher standard now because of advanced technology which was first created to meet the requirements for space exploration. For example, space technologies have helped the research and development of different types of new material. They have also helped companies make better heart monitors and other machines that doctors regularly use. Today, space technologies are widely used in all kinds of industries, and everyday products such as GPS, memory foam pillows, and smartphone cameras are changing our lives.

Finally, sending astronauts into space has helped people to think about the world’s problems and even to find ways to solve them. Seeing pictures of our planet as an island in a black sea made people realise that our planet’s resources are limited. In order to provide for such a rapidly increasing population, scientists are trying to find other planets that could one day be our new home. The greatest attention at present is on Mars because it is closer to Earth. In the future, humans may live on both planets.

Is exploring space worthwhile?
Recently, students in our class have had a heated discussion on whether space is worth exploring. Students’ opinions differ.
30% of us argue that space exploration is not worthwhile. They think space is too distant from us and our daily life and is a waste of money. The money spent on space exploration could have been used to solve the earth’s other problems such as starvation and pollution. On the other hand, 70% advocate exploring space because we have enjoyed a lot of benefits by doing so, such as using satellites for communication and weather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day. Finding new resources through space exploration also contributes to alleviating the problem of energy shortages on the earth.
As far as I am concerned, it is worthwhile to explore space. Not only can it help tackle many problems on the earth, but it enables us to know about new planets and even find a new home in the future.
