Final answer:
The passage implies that despite plastic's convenience, its negative environmental impacts, accumulation in landfills, and recycling inefficiency necessitate a reduction in its use.
Step-by-step explanation:
Based on the evidence from the passage, the most likely inference we can draw is that while plastic makes life convenient, the numerous disadvantages associated with its use, particularly the environmental impacts, suggest that its use should be reduced. The passage clearly states the accumulation of plastic waste in the environment, particularly in landfills, and points to the inefficiency of current recycling efforts. Only 9% of all plastics have been recycled, highlighting the fact that increased production, especially of single-use plastics, does not necessarily lead to higher recycling rates. Moreover, it points out the environmental problems caused by plastic pollution, such as harming wildlife and contributing to air and water pollution.
