Garbage is a big problem. Even with so many of us doing our bit to help out with recycling, the amount of unrecyclable and discarded plastics in the US alone comes close to 30 million tonnes annually, thanks to things like disposable coffee cups (2.5 billion of which are thrown away by Americans every year). We’re looking at you, Starbucks.

It says half is converted into carbon dioxide. Would that be an issue if meal worms were implemented on a huge scale to eliminate plastic waste?
The issue is carbon dioxide levels are up to 400 ppm and prior to this recent increase, they have been below about 300PPM for the last 650,000 years so it's historically a relatively high concentration. Not just CO2, but methane concentration has also increased. Here's the graph for CO2:

Don't most plant use carbon dioxide during photosynthesis? Don't you exhale carbon dioxide with every breath you take? So really what is the issue?
In 2013, CO2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air.
