Given that people frown upon the use of plastic, it is time that we set such kind of thoughts aside and think about the general environment. Most of the time, plastic has been associated with being a pollutant, and it is not a lie. There are millions of people making use of plastic bags, and it is a known pollutant in the seawater as well as any other water sources. It leads to a lot of problems in the marine life, as well as in the sewage disposal system.
However, the use of plastic plates is going to bring about a noticeable change to the water table. Due to the massive irrigation and the use of fresh water by the general population of people across cities all across the world, water tables are noticeably decreasing. If this continues, within a few years, there would be a lack of fresh water and all the resources in order to get cheap water would decline. The use of plastic plates can somewhat curb that downward spiral.
With the incorporation of plastic plates on important occasions, there would be no need for people to spend water in cleaning the cutlery. The people will easily be able to eat on top of the plastic plates, and simply throw it away after they have completed. So, although this is a very small step in this area, but it is a substantial step towards taking care of the environment.
