An Ancient Thread Of “Inseparable Oneness”: A Theoretical Exploration Of Community And Kinship In Grassroots Environmental Justice Movements, Izzy Dean Jan 2023

An Ancient Thread Of “Inseparable Oneness”: A Theoretical Exploration Of Community And Kinship In Grassroots Environmental Justice Movements, Izzy Dean

Pitzer Senior Theses

This thesis arose from a particular fascination and frustration with the prescribed nuclear family unit and the competitive isolation that capitalism breeds within normative communities, particularly in the United States. In this paper, I use the approach of theoretical exploration combined with case study research to explore the role of community and kinship within grassroots environmental justice organizations. I initially wanted to explore examples of people and groups who found strength and resistance by engaging in “non-normative” or “queer” community-building practices. I have since redefined my topic as a broad theoretical exploration in which I cite theories of non-normativity, among …

Growing Culturally Relevant Food At The Urban Farm: An Examination Of Sovereign Foodways, Place-Making Practices, And Autonomous Identity-Shaping, Dahlia Bess Zail Jan 2023

Growing Culturally Relevant Food At The Urban Farm: An Examination Of Sovereign Foodways, Place-Making Practices, And Autonomous Identity-Shaping, Dahlia Bess Zail

Pitzer Senior Theses

This paper examines channels of culturally relevant food production on the urban farm. It further investigates the connection between this production and the shaping of sovereign foodways, as well as how urban farm models provide space and resources for place-making practices and autonomous identity-shaping. This thesis shifts away from the notion of access to culturally relevant food and instead focuses on the multi-fold context that any food item takes on through its production, distribution, and consumption. This allows for a nuanced understanding of the role that culturally relevant food can play in immigrant foodways. Through case-studies at three urban farms …

The Effect Of Blue Mussel (Mytilus Edulis) Extinction On Ecosystem Function In The Gulf Of Maine Rocky Intertidal, Sophia K. Montague Jan 2023

The Effect Of Blue Mussel (Mytilus Edulis) Extinction On Ecosystem Function In The Gulf Of Maine Rocky Intertidal, Sophia K. Montague

Honors Theses

Stressors associated with climate change including thermal stress and ocean acidification inhibit the growth and reproduction of many species, including the ecologically and economically important blue mussel species in the Gulf of Maine (GOM). Established scaling relationships between mussel size, abundance, and water filtration suggests that the decline of mussels will stunt GOM water filtration. This change in the rate of water filtration could have large effects on the abundance of phytoplankton, abundance of invertebrate larvae, abundance of nutrients and organic material, food web stability, and biodiversity. Overall, this thesis explores the effect of blue mussel (Mytilus edulis) …
