Environmental impacts of fast fashion

Last month, my supervisor Dr. Kai M.A. Chan was invited to talk to Global news about the environmental impacts of fast fashion. He is very busy, especially nowadays, so he asked me if I could do it. I agreed to do it and here is the result….


A few things to learn about the fashion industry:

Some of the environmental impacts of fashion:

  • Litter in landfills: Approximately 85% of the clothing Americans consume, nearly 3.8 billion pounds annually, is sent to landfills as solid waste, amounting to nearly 80 pounds per American per year
  • Water pollution: In countries like India or Bangladesh where most of the textiles are done, water pollution is a major issue. To get the colours right, pure water is needed, and often a few rounds of dying. Synthetic fibres like polyester are particularly difficult to dye. Sometimes sewage water is untreated and ends up in rivers and lakes.
  • Health-related problems: the people making our clothes are working in poor conditions and their health is often in peril. For instance, the blue dust from blue jeans is a heavy irritant to the lungs.

Some great things happening in this industry:

  • Brands are rethinking local systems: For example, British fashion designer Bethany Williams‘ “Breadline” collection saw her partner with UK supermarket Tesco and the Vauxhall Food Bank to create a “cycle of exchange”. Tesco donate food items that food bank users can exchange unwanted clothes for. Williams then created her collection using donated garments and Tesco-branded organic prints. The collection is 100% sustainable and 30% of profits are invested back into the food bank.
  • Fast fashion brands are committing to the environment: For instance, H&M has committed to use recycled and sustainably sourced materials by 2030, and plans to adopt a “climate positive” value chain by 2040.
  • Brands are creating sustainable materials: For example, Allbirds, a footwear brand, developed SweetFoam, a material derived from sugarcane, named one of Time Magazine’s 50 Best Inventions in 2018. Allbirds is taking its findings and sharing them with other brands to create a global sustainable production cycle.
  • The State of Fashion 2019: A year of awakening… Every year the consulting firm McKinsey & Company writes the state of fashion report. For the first time sustainability appeared as a major concern in the fashion industry. Great news! Sustainability is no longer something that the industry needs to think about tangentially, now it also makes sense for business.
  • Designers are awesome: Designers (of all kinds) are the most creative minds in our societies. Let’s work with them (By this I mean let’s gather scientists, sustainability scholars, and designers) to create sustainable designs for fashion and beyond… If we partner with designers we can come up with more eco-friendly solutions!

I have a personal journey with fashion. When I was 15 or so, I was obsessed with fashion, I knew the names of all the top models, Colombian fashion designers and many international ones. I spent many, many days watching Fashion TV (Btw, I don’t think this channel exists anymore). Additionally, I have always felt really close to the fashion industry because my sister works for this industry as a marketing expert, my brother in law worked for a Colombian brand as a logistics expert, and my cousin is a fashion designer. All of them taught me so much about this industry, and here are a few things that I wanted to share in the interview, but time was limited.


Birds of Guanacaste Research Project

Have you gone birding in Guanacaste, Costa Rica? Do you want to be a participant in my research project?

The purpose of my research is to better understand people’s preferences towards birds in Guanacaste. I would also like to understand the reasons that drive people’s preferences, including some stories that you may want to share about different bird species.

Participation in this research involves completing an online survey that will take about 25 minutes to complete. Some demographic information will be collected in this survey. Participation in this project is entirely voluntary, but your participation would be greatly appreciated.

If you are interested in helping me with my research, please click on this link:

Beautiful wings, bitter tragedy

His wings are bluish-green, glistening in the sunlight. They have a black band in the middle. His abdomen is yellow. He is 20 cm in length, flying free in the rainforest canopies of New Guinea. He is the Queen Alexandra’s Wingspan, the largest butterfly on the planet. He is so beautiful that some are willing to pay US$10,000 for his wings[1]. And what do they do with them? Put them in a box, together with other wings of beautiful butterflies that come from all over the world to build up an eccentric collection of dead butterflies. My stomach turns at the thought, butterflies behind glass: beauty seen, beauty not felt … lifeless.[2]

For years, people all over the world have traded wildlife illegally. Their purpose is to meet consumer demands for trophies, exotic foods, decoration, traditional medicines and collections.[3] Wildlife trade is a multi-billion dollar industry that threatens biodiversity and triggers ecological problems. For instance, one ecological consequence of wildlife trade is the cascading ecosystem-level effects of removing species[4]. Poaching tigers for their coats, for example, might drive them to extinction. Thus, if tigers become extinct, food chains will likely be severely altered because of the removal of a top predator. Wildlife trade also introduces invasive species. As an example, ornamental fish have been traded to meet the demands of aquarium hobbyists, but in some cases not all the fish in the market are sold. Many sellers release these unsold fish into aquatic habitats where they can potentially threaten the persistence of native species by outcompeting them[5].

Why is the story of butterflies an important example of wildlife trading? Illegal trade of butterflies has more demand than one might imagine, and it is linked to ecological problems such as the loss of pollination as well as social problems like drug trafficking and violence.

People often believe that collectors—particularly those collecting eccentric things, like butterflies—are few in number and spend lots of money maintaining their hobbies. But in fact there are many collectors from the United States, Germany, and Japan (where an estimated 1 in 10 males are serious collectors) interested in buying rare butterflies [6]. In her recent book ‘Winged obsession’, Jessica Speart showed that ‘illegal trafficking of butterflies brings around US$200 million a year to global economy’1. Moreover, harvesting and exploitation of butterflies has increased because they are now trendy and ‘used in greeting cards, paper weights and even jewelry’[7]. The illegal trade involves not just few butterflies, but many thousands!

So… What ecological and social problems are linked to the trade of butterflies? Among insects they are the second-most important pollinators globally[8]. Butterflies pollinate large, showy flowers, pink or purple in color and usually scented, such as hydrangeas or lilacs[9]. Thus, killing and trafficking them can lead to the loss of pollination as an ecosystem service in flower crops[10]. Butterflies are also at the base of food chains; a reduction of their populations would impact the populations of species that prey upon them, such as birds or bats. Moreover, each species of butterfly uses a specific plant or a group of plants for egg laying and larval development; therefore butterflies’ extinction can trigger a coextinction process between them and their host plants[11].

In addition to potential ecological and economic problems from butterflies’ removal, more complex social dynamics involving illegal activities arise from butterfly and wildlife trade. As a matter of fact, the primary actors involved in these activities are criminal syndicates, insurgency groups and terrorist groups4,[12]. In Latin America for example, there is evidence that the routes employed for trafficking drugs are the same as those employed for illicit wildlife and operated by the same criminal bands4. Thus, trafficking butterflies (as an example) may often be linked to violence, corruption and highly organized criminal groups (like the Medellin drug cartel in Colombia or the Italian Mafia)4. Thus, if someone buys a butterfly for a collection, they may be contributing to financing criminal bands that commit terrorist acts.

I know that this topic seems overly dramatic. Connecting butterflies trade with criminal violence? You may think this is too extreme. But the truth is, environmental problems are intertwined with social problems in one way or another. To finish, I want to share with you my ideas about how to deal with this problem:

  • Raise awareness. Did you know the prevalence and significance of the butterfly trade before? Go tell your friends!
  • Stop buying butterfly cards, bracelets, earrings, etc., and speak out whenever you see or hear  about it. We as consumers have the power to shape the market and reduce the pressures leading to illegal butterfly trade.
  • Work to prohibit rare butterfly collections, perhaps by sending letters to politicians or starting  campaigns. In that way we can better prevent extinction of certain species-at-risk.

These are some I can come up with, but what do you think we should do?
