The Problem With Science’s Plastics Addiction

Alice Bell

Scientific research is one of the more hidden users of disposable plastics, with the biomedical sciences a particularly high-volume offender. Plastic petri dishes, bottles of various shapes and sizes, several types of glove, a dizzying array of pipettes and pipette tips, a hoard of sample tubes and vials. They have all become an everyday part of scientific research. Most of us will never even see such equipment, but we all still rely on it. Without it, we wouldn’t have the knowledge, technologies, products and medicines we all use. It is vital to 21st-century lives, but it is also extremely polluting.

An Ethical and Sustainable Guide to Eating Meat

Lee Johnson

While agriculture in general – including the production of plant-based foods – is a source of pollution due to fertilizers, pesticides and other factors, the fact that 30 percent of all crops are ultimately fed to livestock means that meat takes a substantial proportion of the blame. Eutrophication of water bodies, for example, results from an excess of nutrients and things like animal excrement and leftover feed. This leads to overgrowth of algae and plants, using up all of the oxygen in the region and having serious impacts on other aquatic species

Surprising Facts About the Carbon Footprint of Your Favorite Foods

Soila Apparicio

Blanket agricultural production doesn’t work across the world, and it’s important to consider local ecosystems when looking at how best to produce food with the lowest carbon footprint. A vegetarian typically has a smaller carbon footprint than a meat-eater but the plant-based diet isn’t practical everywhere, especially for those who live in dry or cold places that cannot support the growth of most vegetable crops.
