Environmental history is the study of human interaction with the natural world over time, emphasising the active role nature plays in influencing human affairs and vice versa. Environmental history first emerged in the United States out of the environmental movement of the 1960s and 1970s, and much of its impetus still stems from present-day ...
Hart wrote the 1999 follow-up A View from the Year 3000, [33] voiced in the perspective of a person from that future year and ranking the most influential people in history. Roughly half the entries are fictional people from 2000 to 3000, but the remainder are taken mostly from the 1992 ranking, with some sequence changes. [34] [35]
Human ecology has a history of focusing attention on humans' impact on the biotic world. [1] [34] Paul Sears was an early proponent of applying human ecology, addressing topics aimed at the population explosion of humanity, global resource limits, pollution, and published a comprehensive account on human ecology as a discipline in 1954. He saw ...
The period since 1950 has brought "the most rapid transformation of the human relationship with the natural world in the history of humankind". [106] Through 2018, humans have reduced forest area by ~30% and grasslands/shrubs by ~68%, to make way for livestock grazing and crops for humans. [107]
Human history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers.They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
Anthropic arguments FHI has studied include the doomsday argument, which claims that humanity is likely to go extinct soon because it is unlikely that one is observing a point in human history that is extremely early. Instead, present-day humans are likely to be near the middle of the distribution of humans that will ever live. [14]
In the history of the Earth, many Ice Ages are known to have occurred. An ice age would have a serious impact on civilization because vast areas of land (mainly in North America, Europe, and Asia) could become uninhabitable. Currently, the world is in an Interglacial period within a much older glacial event. The last glacial expansion ended ...
The human population exploits and depends on many animal and plant species for food, mainly through agriculture, but also by exploiting wild populations, notably of marine fish. [10] [11] [12] Livestock animals are raised for meat across the world; they include (2011) around 1.4 billion cattle, 1.2 billion sheep and 1 billion domestic pigs. [12 ...
