Invasive Species: Causes, Impacts & Environmental Effects

Invasive Species: Causes, Impacts & Environmental Effects
Invasive species are plants or animals introduced to new environments where they cause environmental, economic, or health harm. Unlike exotic species that coexist peacefully, invasives thrive without natural predators, reproduce rapidly, and disrupt native ecosystems. They're the second-leading cause of species extinctions globally, costing an estimated $120 billion annually in the United States alone. One…

What We Wish We Had Known before Majoring in Environmental Science

What We Wish We Had Known before Majoring in Environmental Science
Environmental science students consistently identify four critical areas they wish they'd understood before starting their major: the foundational importance of chemistry across all specializations, the competitive nature of introductory science courses, the long-term value of professional networking from day one, and the significant adjustment required for university-level science education. These insights come from hundreds of…
