Unit 7 Essay : How to ensure a sustainable future

     Increase in population and wealth has leaded to people's appetites for more beneficial life. This makes the natural resources on earth scarce because the rate of people’s consuming the natural resources is much faster than the rate of the nature’s replenishing the sources. For instance, there is not only a plenty of deforestation over the world, but also too much CO2 gas leading climate change. However, we can ensure a sustainable future by two simple things ; using a public transportation and taking a personal tumbler.

     The first thing that we can do to save the environment is using a public transportation. We can take subway or bus when commuting. By taking a subway or a bus, it is possible to reduce CO2 gas emitted in the air. According to the Department of the Environment, a personal car usually emits 0.194kg of CO2 gas per 1km, which is seven times more than a bus does. Also, using transportation saves the resources needed to make vehicles such as private cars and motorcycles. In fact, it has the same effect of planting 159 of young pine trees per year to use public transportation once a week for a year.  Moreover, it lessens heavy traffic on the road especially in rush hours.

     The other thing that we can do is taking a personal tumbler when we are outside. If we use a tumbler, we can save the resources needed to produce disposable cups made up of paper and plastic. Therefore, using a tumbler can prevent deforestation and the environmental problems resulted from recycling and disposal of plastic. For example, when 12 persons save one of paper cup every day, this could be like the effect of planting a 20-year-old tree. In addition, you can get a little discount at cafes if you take your tumbler. Some cafes give a 10 percent discount to people taking their tumblers.

      In your daily life, you can make sustainable future easily by using a public transportation and personal tumbler. Although they don’t seem to be big changes, they can contribute to environment since they become large movements when gathered. Thus, it’s important for us to always keep those in our minds and try to do make actions.
