Keywords
πŸ’‘Environmental Science
Environmental science is the study of interactions between natural systems (such as the Earth's land, water, and living systems) and human systems (like populations and societies). As Mr. Andersen states, 'Environmental science is the study of the interactions between the systems of the Earth and the human systems.' The video emphasizes the importance of understanding these interactions to ensure sustainability and mitigate negative impacts on the environment.
πŸ’‘Sustainability
Sustainability refers to living and operating within the Earth's boundaries or limits, without depleting or damaging natural resources and systems. The video stresses that 'to live within those boundaries, it is important that we understand the concept of sustainability.' It highlights the need for sustainable practices, especially in areas like industry and resource usage, to prevent exceeding the Earth's capacity and causing catastrophic consequences, as illustrated by the example of Easter Island's deforestation and population decline.
πŸ’‘Planetary Boundaries
Planetary boundaries are the safe limits within which human activities should operate to avoid causing unacceptable environmental changes that could endanger Earth's systems. The video discusses the model proposed by Johan Rockstrom and the Stockholm Resilience Center, which identifies nine planetary boundaries, such as climate change, ocean acidification, and biodiversity loss. It emphasizes that humanity is currently exceeding several of these boundaries, putting pressure on the Earth and risking societal consequences.
πŸ’‘Ecological Footprint
An ecological footprint refers to the amount of natural resources and land area required to sustain a particular population or individual's lifestyle. The video mentions that people in developed countries generally have a larger ecological footprint due to higher resource consumption. As developing countries become more industrialized, their increasing footprints will put even more pressure on the planet's resources and systems.
πŸ’‘Scientific Method
The scientific method is the systematic process of inquiry used in scientific research, involving steps like asking questions, conducting investigations, analyzing data, and drawing conclusions. The video emphasizes that, as a science course, AP Environmental Science should involve practicing the scientific method, such as through field investigations, case studies, and data analysis. Students are encouraged to 'act like environmental scientists' and apply the scientific process.
πŸ’‘Practices of Science
The practices of science refer to the skills and approaches used by scientists in their work, such as asking questions, designing experiments, analyzing data, and communicating findings. The video highlights that the AP Environmental Science course focuses on these practices, encouraging students to engage in activities like conducting investigations, analyzing case studies, and interpreting data sets, rather than just passively learning content.
πŸ’‘Rachel Carson
Rachel Carson is an influential figure in the modern environmental movement, whose book 'Silent Spring' raised awareness about the harmful effects of pesticides like DDT on the environment and wildlife. The video introduces her as 'an important figure' who 'brought us into the modern age of environmental science' by documenting the negative consequences of human activities on the natural world.
πŸ’‘Climate Change
Climate change refers to long-term shifts in global or regional climate patterns, primarily driven by human activities like burning fossil fuels that release greenhouse gases into the atmosphere. The video identifies climate change as one of the key planetary boundaries that humanity is currently exceeding, with significant consequences for society if temperature increases continue at the current rate.
πŸ’‘Biodiversity Loss
Biodiversity loss is the ongoing decline in the variety of plant and animal species on Earth, often caused by human activities like habitat destruction, pollution, and overexploitation of resources. The video cites biodiversity loss as one of the planetary boundaries being exceeded, with some scientists warning of a potential 'sixth extinction' event caused by human impacts on the environment.
πŸ’‘Industrialization
Industrialization refers to the process of social and economic development characterized by the rapid growth of industries and the adoption of industrial manufacturing processes. The video positions industrialization as a driving force behind many environmental issues, as it led to increased resource consumption, pollution, and exceeding of planetary boundaries. However, it also suggests that industry must now play a role in developing sustainable solutions to mitigate these impacts.
