Plastic is not bio-degradable and neither do they fully degrade, which means that the plastic exits in the environment forever.
The D.C Department of Public Works stated in an interview that the best way to keep plastic out of landfills and oceans is to not use it at all.
Keeping that in mind, we can definitely bring about a change in the environment and the ocean life, through the use of eco-friendly reusable straws.
Some alternatives are stainless steel, bamboo and glass. Some restaurants are incorporating spagetti for straws.
