Energy efficiency uses technology to perform the same tasks with less energy, while energy conservation involves behavioral changes to reduce energy use. Both are…
Persistent, Bioaccumulative and Toxic (PBT) chemicals are substances that resist degradation, accumulate in living organisms, and cause harmful effects. They pose long-term risks to…
An ecological trap is a low-quality habitat that organisms mistakenly prefer over better alternatives, often due to misleading environmental cues. This phenomenon can lead…
Marine heatwaves—prolonged periods of unusually warm ocean temperatures—are increasing in frequency, intensity, and duration due to human-caused climate change. These events disrupt marine ecosystems,…
Attributional life-cycle assessment (ALCA) describes the environmental flows of a product system using average data, while consequential life-cycle assessment (CLCA) evaluates how those flows…
Coral reef tipping points occur when cumulative stress—especially from marine heatwaves—pushes a reef ecosystem past a critical threshold, triggering rapid, often irreversible degradation such…
Eutrophication is the process by which a water body becomes enriched with nutrients, leading to excessive plant and algal growth. A harmful algal bloom…
Crop rotation is the planned sequence of different crops on the same land over time, a foundational agricultural practice that improves soil health, reduces…
