ENVS 1000U Lecture Notes - Lecture 1: Coevolution, Consumerism, Bionics
Document Summary
It is the sum total of our surroundings. It consists of both: biotic actors: the living things, abiotic factors: non-living things. It is the common use of term: separates humans from the rest of nature. Humans are part of the environment and part of the natural world. Even so human interactions with our environment are important. Human impact 1: population growth that has affected resource availability. Human population has increase to more than 7 billion. That is due to a series of revolutions throughout human history, such as: agricultural revolution(s, industrial revolution, medical-technological revolutions. Population growth changes relationship with each other and the environment. Human impact 2: excessive consumption reduces resource availability. The increase"s in human population worsen the environmental problems: although, consumption of resource has risen faster than population grow. Excessive consumption leads to resource limitations that are unsustainable. Renewable resources such as sunlight, wind energy, wave energy, and geothermal energy cannot be depleted.
