today we started class with going over the europe map and then we started going over chelsea kara and ana's presentation over overpopulation
it's a condition where the number of organisms in an area or habitat exceeds its carryin capacity
causes- increase in births, decrease in deaths cause of medicines
the average number of children a woman has is 7 or 8, this occurs in mostly third world countries
overpopulated countries- china, US, haiti, pakistan, ethiopia, madagascar, malawi, sudan, uganda, zimbabwe, united kingdom, nigeria
over popultation is not just about how many people there are but by how much impact on the environment each person has on that country
global effects- animals are becoming extinct, more cars= more pollution, increased deforestation, human communities are too dense and produce wastes, over half of the earth's wetlands are gone
more effects- higher percentage of poverty, high birth rate, low life expectancy, social problems, poor diet, high crime rate, poor diet and living conditions
prevention- abstinence and birth control, limit immigration, limit number of children that a family can have
world- 6.7 billion
US- 300 million
Iowa- 3 million
harlan- 5500
after we finished their presentation we went over the europe map again
