Plastic goods enable the world we live in. For example, it would be interesting to see a mouse, and keyboard, and monitor housing made out of bronze, or wood, or cast iron, but I bet they would be worse in pretty much every other way — heavier, harder to shape, and very expensive not only because of the cost of materials, but because they'd take so much more work to make.
When I look around at all the plastic stuff around me, I think that some of it is unnecessary, but much of it isn't. Some of the necessary stuff could be made out of other materials, but much of it couldn't. At least not very well, and not at a price many people could afford.
Better for us if we can figure out a way to effectively recycle plastic, and capture microplastic in the wild.
#2 on the list is everybody else. Once you start looking at what is made out of plastics you'll realise the modern world is completely dependant on it. The use of plastics on food and medical devices dramatically reduces bacterial contaminantes saving millions of people a year from sickness. It's used on structural components of all kinds of device to reduce weight, thereby decreasing energy usage. It is a very difficult problem to solve.
However I think it should be banned from any and all contact with foodstuffs.
