Bottled water, dairy products, juices, soft drinks, etc. in plastics may not be such a great idea.
Bottled water does contain microplastics. Matter of fact microplastics are abundant everywhere, even found in seabirds on remote islands.
I believe they are more of a threat to the environment than “climate change” will ever be.
My packaging professor researched biodegradable plastics for this very reason.
The problem is such plastics are more expensive. Engineers can certainly produce them, but if one adds even 1/100th of a cent to costs management will not want it.
In some areas, namely Europe, Taiwan, Korea and Japan the end user of non-recyclable, non-biodegradable packaging must pay a disposal fee.
This is one instance where government does have a role; companies should not be able to externalize their costs on the general public and wildlife.
Almost all food is in plastic now. Even our clothes are plastic.
