Human Population Trends
How does geography/ climate affect and still affecting human migrations?
Rural to Urban movement
The different climates and the impacts of them
How did humans adapt to various biomes?
Deserts: A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life.
Taigas: Taiga, generally referred to in North America as boreal forest or snow forest, is a biome characterised by coniferous forests consisting mostly of pines, spruces, and larches.
Grasslands: Grasslands are areas where the vegetation is dominated by grasses; however, sedge and rush families can also be found along with variable proportions of legumes, like clover, and other herbs.
How do humans decide where they are going to live?
Creation of cities due to the geographic features like:
Lakes: so humans can grow food (indicates the surrounding land is fertile), have access to clean water (to feed their population) and also so they have access to water to produce different types of items
Rivers: Important for vegetation (since rivers indicate the surrounding land is fertile), access to oceans or seas (ease of trade and help from neighbouring countries/ cities)
Mountain Ranges: Protection against any incoming attacks (way harder for the opposition to bring fleet into cities if they have geographic protection), usually is seen in the outskirts of cities.
Near Seas: Seas have a good temperature to them (not too cold and not too warm), land near seas are also predominantly flat (making cities a lot easier to construct due to building buildings on flat lands), access to trading routes and more control over these trading routes (makes cities able to trade with many other countries, increasing their overall economy).
Neighbouring countries and protection against them
Geographic features such as islands and mountains help countries and cities be protected against any attacks that might occur to them due to any conflict that might occur.
How do countries build good diplomatic ties? What has caused tensions between countries and how does geography play a role in this?
What is the impact of humans moving from one area to another?
Humans moving to a new place will cause many environmental reasons:
Deforestation: Clearing out forests and other biomes to create room for infrastructure to house peoples and cities
Pollution: Due to the need and demand of electricity, people will start burning coal and other fossil fuels to produce electricity which would help provide homes with electricity, factories so they can produce goods and agriculture for more efficient technology
Pollution of the water: Due to the need of water, humans will start using the clean water from lakes and rivers, leaving many to be contaminated and polluted.
Loss in biodiversity: Due to deforestation and clearing out biomes to provide an area for the human population, many plants and animal species will go extinct or have to move away, causing the biome to be harmed and more vunerable.
This will grow and expand the countries businesses and make their economy more diverse:
Due to many areas of the world having different resources, this will cause countries to extract other resources and start using them or sell to the global market, boosting their economy
A new city will also host other factories and areas to produce items to be sold, causing a boost in the local and national economy.
How does human populations get affected by climate change?
The changing climate leaves an array of problems to the biomes and the ecosystem the human population resides in.
Loss of biodiversity: the change in biomes will also change the biodiversity of the region due to the fact that climate change happens in such a rapid pace that animals and plants won't be able to adjust, therefore causing populations and species to go extinct or to be relocated.
Rising sea levels: the rising sea levels causes a huge threat to populations living on the coastal parts of countries (which is most of the human population), causing floods, tsunamis and submersion of land.
Desertification & degradation of land: The land and soil will become less fertile due to the temperatures increasing, causing the evaporation and disappearance of water. Due to this, may cities currently, are facing a problem with having enough food and water to feed their populations
