Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [1][2] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [3] Plastics are inexpensive and durable ...
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be molded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive ...
Plastic bans are laws that prohibit the use of polymers manufactured from petroleum or other fossil fuels, given the pollution and threat to biodiversity that they cause.A growing number of countries have instituted plastic bag bans, and a ban on single-use plastic (such as throw-away forks or plates), and are looking to spread bans to all plastic packaging, plastic clothing (such as polyester ...
The microplastics are such a concern because it is difficult to clean them up due to their size, so humans can try to avoid using these harmful plastics by purchasing products that use environmentally safe exfoliates. Because plastic is so widely used across the planet, microplastics have become widespread in the marine environment.
Marine plastic pollution. The pathway by which plastics enters the world's oceans. Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish ...
A plastic bag ban or charge is a law that restricts the use of lightweight plastic bags at retail establishments. In the early 21st century, there has been a global trend towards the phase-out of lightweight plastic bags. [1][2] Single-use plastic shopping bags, commonly made from low-density polyethylene (LDPE) plastic [citation needed], [3 ...
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.

How to Store Mushrooms. Mushrooms need to breathe, so storing them in paper bags is a great way to keep them safe while encouraging airflow. Zipped plastic bags tend to seal in moisture, though ...
