2B2 - Environmental Impact on Human Civilization Flashcards
Examine how the environment impacts and changes human civilization.
What is an agrarian society?
A society where cultivating the land is the primary source of wealth, focusing on agriculture and farming.
Why did humans first start to settle down?
To switch to an agrarian society, which required good quality, fertile soil and a strong water supply.
Humans began living a settled life to avoid wandering for food. They began living near sources of food and water.
Identify:
Natural resources were important for settlements?
- Wood (trees)
- Stone
- Metal ores
- Gold
- Silver
- Oil
- Coal
Explain:
Push factors related to climate change
- Increased frequency and intensity of hurricanes, floods, and wildfires can devastate communities, prompting residents to flee for safety and stability.
- Prolonged droughts can lead to crop failures and diminished water supplies, making it difficult for people to sustain their livelihoods and forcing them to seek more hospitable areas.
- Coastal communities face the threat of flooding and loss of land due to rising sea levels, leading to displacement as residents move inland to escape inundation.
What are some examples of rare and expensive natural resources that attract people to settle in an area?
- Gold
- Silver
- Oil
Besides natural resources and money, what other factors can attract people to settle in a specific area?
- Warm, temperate, and pleasant climate.
- Feeling safe from natural disasters like hurricanes, earthquakes, and volcanoes.
What role did original agrarian societies play in determining where humans settled?
Chose settlement locations based on access to fertile land and water sources for agriculture. Many also chose rivers near coastal regions.
Explain:
Modern factors related to where humans settle
- Access to jobs, industries, and commercial hubs drives people to settle in urban and economically developed areas.
- Favorable climate conditions, natural resources, and low disaster risk areas are preferred for comfort and safety.
- Access to healthcare, education, transportation, and reliable utilities such as water and electricity are key factors in determining settlement locations.
What are 3 factors that influence agriculture productivity?
- Soil
- Water availability
- Climate
How does the environment impact human health?
Polluted air and water can lead to respiratory illnesses, cardiovascular diseases, and waterborne infections.
What is a way that natural habitats impact the spread of disease among humans?
Close proximity to tropical regions with mosquitoes can lead to outbreaks of diseases such as dengue fever and malaria, that infect humans through insect vectors.
How does climate change impact human civilizations?
- Driven by human activities, it affects weather patterns, sea levels, and ecosystems.
- This leads to increased frequency of extreme weather events such as hurricanes, heatwaves, and floods.
How does access to natural resources affect humanity?
Because natural resources are not evenly distributed
around the world, whoever controls a region with natural resources (like oil) are able to impact neighboring countries.
Why are ecosystems important?
- Healthy ecosystems provide services such as pollination, water purification, and carbon capture.
- Loss of biodiversity can disrupt these services, affecting agriculture, clean water supply, and climate regulation.
How does geography influence the growth of human civilization?
- Rivers, coasts, and fertile plains attract dense populations.
- Arid or mountainous regions often remain sparsely populated.
