Ecology: Examining the Relationships Between Living Things

Ecology is the scientific study of relationships between living organisms and their environments. It examines how species interact with each other and with the physical world around them — from microscopic bacteria in soil to the cascading effects of climate change on global ecosystems. Ecology underpins nearly every environmental science career and discipline. If you've…

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…

Phytoliths: What They Are and What They Tell Us

Phytoliths are microscopic silica structures that form inside plant cells and survive long after decomposition, providing evidence of ancient plant life and environments. These "plant stones" help archaeologists and environmental scientists reconstruct past ecosystems, understand early agriculture, and trace human impacts on landscapes dating back thousands of years. Most research roles require a Master's degree…

Birds as Environmental Indicators: What They Reveal

Birds serve as environmental indicators because they respond predictably to changes in habitat quality, pollution, and disease. Scientists study bird populations, behaviors, and physical samples to detect ecosystem stress early — often before other methods reveal a problem. Their sensitivity, visibility, and practical sampling methods make them one of ecology's most reliable monitoring tools. Environmental…

How Birds Support Ecosystems: 4 Essential Services Explained

Birds provide four essential ecosystem services that benefit humans and maintain environmental health: supporting services like nutrient cycling and soil formation, provisioning services including pest control and pollination support, regulating services such as waste decomposition and seed dispersal, and cultural services like ecotourism and spiritual enrichment. These contributions generate billions of dollars in economic value…

Natural Gas 101: Pros, Cons & Career Guide

Natural gas is a fossil fuel primarily composed of methane, formed over millions of years from decayed organic matter. It supplies approximately 22% of global energy needs for heating, electricity generation, and industrial processes. While natural gas burns cleaner than coal or oil—producing 50% less carbon dioxide—its extraction and use raise environmental concerns including methane…

Hydroelectric Power: How It Works, Pros & Cons, and Careers

Hydroelectric power harnesses the kinetic energy of moving water to generate electricity, making it the world's most widely used renewable energy source. It's clean, cost-effective, and capable of producing power at scales ranging from a few kilowatts to over 20 gigawatts. It currently generates roughly 19% of the world's electricity, with careers in the field…

Dendrochronology: How Tree Rings Reveal Environmental History

Dendrochronology is the scientific analysis of tree-ring patterns to date wood samples and reconstruct past environmental conditions. Students from archaeology, climate science, chemistry, and forestry use dendrochronology in their research. Tree rings reflect annual growth influenced by climate, enabling scientists to date artifacts, calibrate radiocarbon testing, and study historical climate patterns spanning thousands of years.…

Is Environmental Science Really a Good Major?

Environmental science is a strong major choice for 2026, with median salaries of $80,060 and projected 4% job growth through 2034. The field combines biology, chemistry, geology, and policy to address real-world environmental challenges, preparing graduates for careers in consulting, government agencies, conservation, and research with approximately 8,500 annual job openings nationwide. When prospective students…

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…
