It is a worldwide fact that products made by plastic, including bottles, cutleries and straws will damage the environment as they are not able to resolve in the solid naturally. Also, during the process of production, a lot of toxic chemicals are released such as benzene, which will pollute the air and further increase the level of climate change. Most people know about it, but theyseldom care. They keep using plastic cutlery when they order take-away food, or even in restaurants just because it is convenient. Buying bottled water instead of bringing their own, again, just because it is convenient. Therefore, I would like to start by myself, start bringing my own mental cutlery and water when I eat outside. Say no to plastic cutlery when I order take-aways, and bring my own cup when buying coffee outside. I believe it is a good and simple way to build the habit of becoming green and sustainable.
