ENVS 1126 – 50+ Exam Questions on Scientific Method, Population & Environmental Issues – Louisiana State University

This document offers a comprehensive set of 50+ solved exam questions from Week 1 of ENVS 1126 (Environmental Science) at Louisiana State University, carefully aligned with the 2025 curriculum. It provides clear and well-explained answers covering the scientific method, hypothesis testing, and core principles of environmental science. A major focus is placed on global environmental challenges, including CO₂ emissions, climate change, and the impacts of fossil fuel use. Students will explore the role of human activities (anthropogenic effects) on ecosystems, the carrying capacity of the planet, and trends in population momentum, fertility rates, and life expectancy. Case studies such as the reindeer of St. Matthew Island, maternal mortality in the U.S., and the collapse of Easter Island’s civilization are used to illustrate the consequences of environmental mismanagement. Additionally, the document includes insight into biodiversity loss, pollution in China, renewable energy sources like wind, and the concept of intergenerational equity. Foundational economic models (capitalism vs. centrally planned economies) and the Green Belt Movement are also addressed to help students connect environmental issues with socio-economic policies. This resource is ideal for: – Undergraduate students in environmental science, public health, sustainability studies, ecology, geography, or environmental policy – Students preparing for quizzes, midterms, or finals in introductory science and environmental studies courses – Learners seeking structured, real-world examples of human-environment interactions, sustainability challenges, and ecological reasoning Keywords: environmental science, ENVS 1126, scientific method, hypothesis, fossil fuels, CO2 emissions, population growth, fertility rate, population momentum, quality of life, maternal mortality, Easter Island, environmental collapse, climate change, biodiversity, sustainability, intergenerational equity, renewable energy, pollution, China environment, wind energy, Green Belt Movement, ecosystem services, anthropogenic impact, environmental economics
