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.
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,
As a result, space-based science has helped farming in its efforts to grow enough food to feed Earth's increasing population.
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

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 and wonder at the photos from space that we see. Having said that, it is hard to believe that the high cost of space flight is justified so that we can get some lovely pictures. We should be spending our money more wisely, on what people need.
