Answer: All of the above
Explanation:
You didn't provide the passage to know what the author wrote but let me help out based on the options given.
It should be noted that only one out of six water bottles end up in recycling. Others that aren't recycled are sent to landfills or sent as trash into seas, rivers etc.
This creates an environmental issue.
Also, plastic bottles take several years to disintegrate and since they're also made from oil, this is hazardous and have a negative effect on the environment.
