Solid and Hazardous Waste

  Honestly, most of my food decisions come down to what's cheap and fast. But seeing the slide that showed beef takes 36,200 calories of input compared to 8,800 for poultry made me pause. That gap is huge, and it's not just about efficiency, it's about the planetary management worldview baked into how we produce food. The mindset that we can engineer our way out of any problem is exactly what the Biosphere 2 case study pushes back on. Eight people, two years, and the whole system fell apart because decomposers ate the oxygen and ants outcompeted everything. If we can't replicate Earth's systems on that small a scale, the confidence behind industrialized agriculture starts to feel a little misplaced. The line that stuck with me most was about "substitution of belief for facts" being a warning sign of past civilization collapses. That feels uncomfortably relevant right now. I'm not planning to go full vegan or anything drastic, but I think shifting towar...

Population, Urbanization, & Sustainability

Image
 After reading this week's topic on Population, Urbanization, & Sustainability I learned how these three interact with one another. Urbanization is present in the Bay Area every year, whether it's new housing developments or more cars on the road. It seems like there are more and more people, which is directly related to the stress on resources we've been learning about. I learned that cities can be both a answer and a problem. By having more people living in cities means more trash, pollution, and energy use, but cities can work better if there are certain things made accessible and mainstream. Ways that are already environmentally friendly are taking the bus or train places and building homes that use less energy. It put the thought into my mind on how important it is to plan for better systems in the future to lessen the impact on people. Population growth changes everyday life in small ways, like when it's hard to find parking or when there are more people in li...

My Blog on Biodiversity

Image
 Biodiversity has been a topic that I have been briefly informed on with other courses, however this week I have had my understanding of the topic be expanded upon and deepend. My initial understanding on biodiversity was about the variety of different species in an ecosystem, but now I have come to realize that it is also connected to topics like evolution, natural selection and genetic variability. Not solely being on how many organisms coexist together but how these lives adapt to their environments over periods of time. Genetic Variability was the topic that stuck out the most to me when going over our lecture, how over time mutations in a organisms genes start to create subsets of species, referred to as gene pools. These gene pools allow the species that has adapted best to its environment to reproduce and continue to survive while the weaker gene pool species are more likely to die off. This process of genetic variability is what allows species to be able to live on in their...

My Recent Revelations on Sustainability

Image
My initial thoughts regarding sustainability categorized it as being basic and ordinary. Reusable grocery bags, reusable bottles, unplugging unused devices, turning off lights, making sure faucets are shut, and, most recognizable to me, recycling were all things I initially thought of when thinking of sustainability. When introduced to the increased scope of sustainability provided in my environmental issues course, I came to the realization that even though these topics have significance and I understand the importance of them, there is a deeper level to understand.  Progressing through the course materials and lectures, sustainability isn't something as simple as a change of habit, but in the grand scheme of things, analyzing how society as a whole consumes a significant amount of resources. I first realized this fact during an earlier lecture in my environmental issues course, where our resources were stated through a graph illustrating how 70% of our resources are used by only ...
