Is it possible for people to travel to stars far from solar system in the future? I came across an article online about NASA's take on that and I'll share it here. The closest star to solar system is "Proxima Centauri" and it means the next closest star to Earth after the sun. It is about 4.2 light-year away. It takes more than four years for even light with about 300,000 km per second to get there. In the case of Voyager1 launched in 1977, it would take about 70,000 year to get to "Proxima Centauri" if it was heading in the right direction. That's why we need the technology that we can move at the speed of light in the future. Terrible accidents might occur even when tiny dusts hit our starship if it could move at the speed of light. We also need the durable starships that can get over the damage. Many countries plan to send people to moon in the near future. We already have some service, such as GPS and Internet, with satellites in stationary orbit. Hence, new produces and new service in between Moon and Earth will come out one day. We still have many challenges to carry out the trip to stars, but it seems like a doable trip. Unfortunately, I don't think I can experience the trip because I definitely will die.

Every household should have a government-imposed limit on the amount of rubbish it can throw away. To what extent do you agree? Waste disposal is one of alarming problems facing today's society. Some say that government should limit the amount of rubbish each household can throw away. I generally disagree with this viewpoint because the amount of waste can vary for various factors, from the number and ages of family members to occasional reasons, such as moving and parties. It is unpractical to set a limit on the amount of waste a family produces. Each family has different reasons to throw away a large amount of waste, including number of members, lifestyle and occasional events. Additionally, there is no alternative but to collect rubbish when a household exceeds the limit. Otherwise serious hygienic problems would happen. On the other hand, governments may be able to regulate the amount of rubbish by ruling waste bags. For example, in many cities in Japan, the city governments require households to put their rubbish in the designated plastic bags, which is priced higher than normal bags. This policy encourages families to reduce waste. In conclusion, it is unrealistic to directly impose a limit on the amount of rubbish although government can nadge households to decrease the amount of waste by several measures, such as pricing garbage bags.
