- Transportation is the largest contributor to U.S. greenhouse gas emissions.
- Nutrient pollution from agricultural runoff is a primary driver of aquatic dead zones.
- Land use patterns are heavily influenced by agriculture, urbanization, and the expansion of renewable energy infrastructure.
- Data interpretation is essential for tracking environmental health, evaluating policy effectiveness, and forecasting future trends.
- Public policy and technological advancements play critical roles in shaping environmental outcomes.
Frequently Asked Questions
What are the main sources of air pollution in the U.S.?
Vehicle emissions, industrial activities, and electricity generation (especially from fossil fuels) are key contributors. Regulatory efforts under the Clean Air Act have led to reductions in many criteria pollutants.
How has land use changed in the U.S. over the last century?
Historically, agricultural expansion was dominant. More recently, urbanization and suburban sprawl have led to significant conversion of agricultural and natural lands, especially in fast-growing regions.
What are PFAS chemicals and why are they a concern?
PFAS (Per- and polyfluoroalkyl substances) are persistent synthetic chemicals found in various consumer products. They are a concern because they don’t break down easily in the environment or human body, leading to widespread contamination and potential health risks.
Which sector contributes the most to greenhouse gas emissions in the U.S.?
The transportation sector currently accounts for the largest share of U.S. greenhouse gas emissions, followed closely by electricity generation and industry.
What is nutrient pollution and how does it affect U.S. waters?
Nutrient pollution refers to excess nitrogen and phosphorus in water bodies, primarily from agricultural runoff and wastewater. It causes algal blooms, which deplete oxygen when they decompose, leading to “dead zones” harmful to aquatic life.
