Reasons for Space Exploration Essay
Humanity was starting the space exploration about 60 years ago. Surprisingly, the first living thing to experience space travel was a fungus. Space exploration is the ongoing discovery and exploration of celestial structures in outer space by means of continuously evolving and growing space technology. Nowadays, many countries have been spent a lot of money on space exploration. If so, why should money be spent on that? There are many reasons that we should be spent money on that. The root reasons are that the sun will be gone, global warming and people are worried about resource exhaustion.
Firstly, the Sun will run out of fuel in 5 billion years and turn into a Red Giant. Because, Helium burning leads to higher core temperatures. The sun is very important and significant presence to people and earth. The Sun is the prime source of the energy that we get from the food that we eat. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth. Also, the Sun provides energy and photosynthesis that is needed for plants to grow. If the sun is disappeared, no one cannot live on earth even plants, animals and microorganism. So, we need another planet that has the light in place of the sun.
Secondly, due to global warming, people cannot live on earth. Global warming will directly impact human health and livelihoods. It is called effects of global warming that are the environmental by human emissions of greenhouses. The Earth’s average temperature has warmed by about 0.76°C over the past 100 years, with most of this warming occurring in the past 20 years. Owing to this problem, the iceberg of the Antarctica and the Arctic is rapidly melting, so sea level is rising by this problem. Also, by sea level rises, the islands which are located in the Pacific Ocean and the islands or the countries of low lands, it could be submerged. Th…
