TOPIC A: KEYTERMS

 Hi Delegates!


This week, I wanted to provide you information about some key terms you should be familiar with. It is vital that you understand these terms, so please familiarize yourself with them by reading the descriptions below!


TOPIC A: 


Microplastics are defined as any plastic under 0.5mm. There are two types of microplastics: primary and secondary. Primary microplastics are tiny particles designed for commercial use. Secondary microplastics are microplastics that form after macroplastics break down. These tiny plastics are difficult to identify, making the clean-up process extremely difficult. 


Biomagnification is the process in which toxins such as microplastics increase in concentration when moving up the food chain. Essentially, polluted species consume other polluted species, and the microplastics accumulate as predators eat prey. 


Microplastic ingestion is when one consumes microplastics when eating or drinking. Even daily activities such as drinking from a plastic bottle could lead to microplastic ingestion. This can also result due to biomagnification. 


Sincerely,

Emma

6 things to keep in mind for resolution writing

  Hi delegates,  As some of you have started drafting a few clauses to bring into committee, I wanted to give a few tips and spearhead ways to solve some of these wicked problems.

This can include banning plastic bags, implementing deposit-return schemes for plastic bottles, and regulating the use of microbeads in personal care products. Support research and development : Governments can fund research and development into new materials and technologies that can help reduce microplastic pollution. This can include supporting the development of biodegradable plastics, investing in wastewater treatment technologies, and e

VICE CHAIR INTRODUCTION - SAMEER AMEEN

Hello! My name is Sameer Ameen and I'm one of your vice-chairs. I'm a second-year intending to do a simultaneous degree in Society & Environment and Rhetoric. I founded the MUN club at my school in the middle of the pandemic and am very excited to be a part of BMUN and its community. I was born in Los Angeles to two immigrant parents from Bangladesh and have traveled to many countries around the world, witnessing firsthand the different cultures and political spheres discussed in MUN conferences. Outside of BMUN, I spend most of my time listening to music, going to the gym, hanging out with friends, and finding good food here in the Bay area.  UNEP is a special committee because it discusses the most prevalent issue in our global community today. The health of the environment decides the fate of our only habitable planet. I am excited to hear all the solutions you come up with!
