Study Notes
Global Environmental Change
- Modern humans (Homo Sapiens) emerged in Africa ~200,000 years ago as hunter-gatherer societies.
- Early human societies had a small environmental footprint due to their small population.
- Humans have an unusually wide variety of food sources compared to other species.
- Humans colonized all land masses by the end of the last ice age (15,000 years ago).
- Human population has risen steadily since the beginning of civilization and exploded within the last few hundred years.
- The internal combustion engine, invented in the late 18th century, revolutionized transportation, construction, agriculture, and manufacturing.
- The Haber-Bosch process converts atmospheric nitrogen gas into ammonia, a vital fertilizer for agriculture, supporting population growth.
- Coal burning in industrial cities caused severe smog in the 19th century, particularly in the United Kingdom.
- Reliance on gasoline-burning automobiles caused air pollution in Los Angeles in the 20th century.
- China and India face severe air pollution today due to reliance on coal-fired electricity plants.
- Deforestation, primarily for agriculture, occurs at a rate of 150,000 square kilometers per year.
- Tropical forests have been reduced from 16 million to 8 million square kilometers.
- Monoculture agriculture leads to the loss of biodiversity by planting a single species over large areas.
- Modern fishing methods have led to the collapse of several regional fisheries, such as the cod fishery off the coast of Newfoundland.
- The ocean faces a multitude of stressors, including pollution, agricultural runoff, fishing, warming, and acidification.
- Coral reefs, which support 25% of ocean species, are sensitive to marine heatwaves and have experienced significant bleaching events in recent decades.
- The majority of the ocean is affected by human activities, including pollution, overfishing, and climate change.
- The discovery of the ozone hole was a major environmental concern, leading to international agreements to phase out ozone-depleting substances.
