Unit 7: (Ensuring a Sustainable Future): Corporate Social Responsibility.

     Sometimes, few eco-friendly actions are quite hard to practice individually. Fortunately, since corporations are responsible for environment pollution, they try to compensate for it. There is a CSR(Corporate Social Responsibility) program for those actions which need to be done by big groups. The great advantage of CSR is that the effect of it is huge since it comes into an action on a large scale. Also, it has a several good effect to a company, because CSR improve‘s the corporation‘s image. A rental car company's tree-planting program and a semiconductor parts company are two good examples.

     Ten years ago, a rental car company noticed the danger of air pollution caused by the pollution emitted from some vehicles and they started a tree-planting program. A foundation established by the corporation plants one million trees a year in USA, Canada and Europe. However, unlike other years, they are working on planting 50 million trees this year to ceremony it’s 10th anniversary and to thank customers for their loyalty. According a study, 10 million trees can absorb more than 10 million pounds of carbon and provide an estimated $27 billion worth of environmental benefits in only ten years. Biodiversity is also one of the great achievement of this project, with over 50 different species of trees planted in over 15 states in USA. Also, as the tree planting program takes air, people started to have a better image on the company. So the program is like killing two birds with one stone.

     In addition, there is another company that started to care about how horrible water pollution is to the local people and to the nature years ago. So it went into constructing wastewater purifying facilities for the local environment. Recently, water shortage has been a huge problem since the water supply will not catch up to the water consumption. So manufacturing wastewater reclamation as a source of ultra pure water will help not only the local people but also industries to get out from that trouble. Besides, the corporation started to use and make environmentally friendly materials, which made the profits of the company increased.

     To sum up, as the environment pollution is getting worse and worse, people need to find ways to make it better. However, since there are few things that government or individual cannot practice, corporations try to live down what they had done to the nature and actively participating in eco-friendly business. A car rental company's tree planting program and an electronic company's water purification program are the examples. Through such activities, companies are making progress in making a eco-friendly world.

Unit 6: Explanatory essay, Martian.

     Some movies could happen in any places. However, in other films, the location of a movie could be a severe ordeal itself to a leading character. Martian is a most-representative among those movies. In Martian, Mars is where every hardships that the protagonist suffers happens. Being left in Mars alone without enough food supplies and solid facilities which can protect him from the harsh environment means death. In order to avoid death and being rescued alive, the main character tries to do everything he can.

     Every event of the movie happens in space, especially Mars. Mark Watney, an astronaut who was given the task of Mars exploration, is presumed dead after a fierce storm and left behind by his crew. However, Mark was not dead and since he was left alone in Mars, he has to find some ways to survive until the next Mars exploration team comes. Since it takes four years for the exploration team to come, he is running out of the provisions. Fortunately, he is a botanist and he tries to grow potatoes with the soil of Mars and water from burning hydrogen and oxygen. Also, he has to be at Schiaparelli, the next exploration team's destination, so he struggles to make a vehicle and to get there in time overcoming many difficulties. Those events could not happen in any other places in Earth, because if it was not happened in outer space but in Earth, being left alone would not be regarded as death.

     Also, the highlight of the movie is when Mark being rescued by his colleagues in space. At the end of the movie, NASA and Mark's colleagues try to save him from Mars. According to a plan, the crews and Mark were to meet at a proper location but there is something wrong with the Mark's spaceship so he has to get out of it and make it to the crews' spaceship. However, he had no electric power to help him get there, so he makes a hole in the palms of his space-suit, which will make him like the Iron Man. This peculiar idea is viable because he is in outer space, not in Earth.

     Those events in Martian cannot happen in Earth, but only in Mars. Due to the martian environment, Mark has to overcome few hardships only to cultivate potatoes and to get to Schiaparelli alive. Also, thanks to one useful feature of space, he is able to fly like the Iron Man by only cutting a hole in his gloves and be rescued alive. As the pollutions of the earth is growing worse and the population expands, many people would have thought about living in other planets at least once. However, have you ever thought about being left alone in other planets with no hope?
