i want to tell you about what we can do to preserve the environment. There are several ways of protection of the environment. But today I’d like to introduce one way we can start easily. That is to use our own bottle instead of buying drinks in plastic bottles. In Japan, a number of plastics are thrown away and this is one of big social problems in our country. When used plastic bottles are burned as a trash, CO2 is emitted. CO2 is one of causes of global warming or other environmental issues. Even if plastic bottles are recycled, during its process or transportation, bad impacts might happen. This is why we have to use our own bottle. If you have one, you don’t have to buy plastic bottles everyday. These days, there are more and more water servers outside and some cafes provide drinks into your bottle. This is not difficult way. So let’s try this for our earth.
