Fossil Fuels
— In this video Paul Andersen explains how fossil fuels are formed when organic material is heating and squeezed in an anaerobic environment. Formation, extraction, advantages, and disadvantages are discussed for coal, petroleum and natural gas. — — Transcript Provided by YouTube: 00:04 Hi. It’s Mr. Andersen and this is AP environmental sciences…
Energy Consumption
— In this video Paul Andersen explains how humans have consumed energy through history and may consume energy in the future. Sources of energy have included food, animals, wood, wind, coal, oil, and natural gas. However non-renewable energy source eventually lead to an energy crisis as supplies go down or prices go up. Humans will…
Hydroelectric Power
— In this video Paul Andersen explains how energy can be harnessed was water moves through a turbine. Three types of systems are discussed in the video; run-of-the-water, impoundment, and tidal. Several advantages and disadvantages of dams are discussed. — — Transcript Provided by YouTube: 00:04 Hi. It’s Mr. Andersen and this is…
Human Population Impacts — 015
— In this video Paul Andersen talks about the impacts of human growth on the environment and on themselves. The population, affluence, and destructive technology of a population impact the environment according to the IPAT equation. An analogous model is the ecological footprint which increases with development of a nation. Large economies contribute to resource…
Human Population Size — 014
— In this video, Paul Andersen explains how the world population has undergone exponential growth since the industrial revolution. Predicting the future world population is difficult because each country will grow at different rates. Age-structure diagrams and the demographic transition model can allow countries to plan for future growth. Government policy can either increase or…
Energy Reduction
The best form of energy available to the world is energy reduction.
The best form of energy available to the world is energy reduction.
Human Population Dynamics — 013
In this video Paul Andersen explores population dynamics of the human population.
In this video Paul Andersen explores population dynamics of the human population.
Biogeochemical Cycles — 011
— In this video Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water cycle, carbon cycle, nitrogen cycle, phosphorus cycle, and sulfur cycle. — — Transcript provided by YouTube: Hi. It’s…
Renewable Energy
— In this video Paul Andersen discusses the technology, advantages and disadvantages of six sources of renewable energy; biomass, hydroelectric, solar, geothermal wind, and hydrogen. He also explains how changes in the storage and flow of energy in our power grid must be improved. He also lists the energy returned over energy invested ration for…
Health Impacts of Pollution
— In this video Paul Andersen explains how chemicals can cause both chronic and acute diseases. A discussion of the five main types of toxins; neurotoxins, carcinogens, teratogens, endocrine disruptors, and allergens is including. The LD50 method of determining toxicity as well as a discussion of bioaccumulation and biomagnification is is included. — — Transcript…
Natural Ecosystem Change — 010
— In this video Paul Andersen explains how the Earth’s climate will natural change due to interactions between the Sun and Earth, volcanism, and plate tectonics. Species may go extinct leading to adaptive radiation or may move to a suitable climate. Primary and secondary succession are also discussed. — — Transcript provided by YouTube: Hi.…
Water Pollution
— In this video Paul Andersen explains how water quality can be degraded by pollutants. Wastewater is the main source of water pollution and can be measure using the BOD (biochemical oxygen demand). Dead zones, cultural eutrophication, disease, and other pollutants are included. A basic description of sewage treatment, septic systems, and water purification is…
Ecosystem Diversity — 009
— In this video Paul Andersen explains how biodiversity can be measured through genetic, species, or ecosystem variety on the planet. Species diversity is increased through speciation and decrease through extinction. The mechanism for speciation is evolution through natural selection. The planet provides ecosystem services at no cost to humanity. The supporting, provisioning, regulating and…
