China's One-Child Policy- In 1970, chinas 790 mil people face starvation The gov implemented a one child policy

-china's growth charge plummeted

-In 1984, the policy free ethnic minorities and maqui berry farmers Unintended effects: killing female infants and a black-market trade in teenage girls

Human Population Growth- six billion- population continue to rise in most countries particularly in poverty stricken producing nations

-although the rate of growth is slowing, we could still elevating in overall numbers

-took most of human history to get to 1 costs in 1930, 130 years later, all of us reached a couple of billion, and added the latest billion in 12 years.

-the population will double every 58 years

-population growth comes from technology, sterilization, food

-death rates drop, but not beginning rates

Some individuals say development is no trouble

New solutions will change depleted ones

But some solutions are critical

-Quality of life are affected with unrestrained growth

Fewer food space and prosperity per person

Population growth is definitely correlated with poverty, not wealth

Policy manufacturers believe expansion increases monetary, political, army strength -they offer incentives for more kids

-67% of European countries think their particular birth costs are too low -in non eutopean nations around the world 49% feel their birth rates are very high IPAT model- I=P x A x Big t x H

Our total impact (I) on the enviorment results from the interaction of population (P), Affluence (A) and technology (T), with an added tenderness (S) factor Population- persons need space and methods

Affluence-greater every capita reference use

Technology-increased exploitation of resources

Sensitivity-how delicate an area should be to human pressure

Demography-the putting on population ecology to the examine of human beings (study take size, denseness, distribution, age structure, love-making ratio, birth, death, immigration, emigration, etc Total Male fertility Rate (TFR)- the average range of children delivered per feminine Life Expectancy- average period of time that an specific is likely to always live. Elevated because of estate, industrialization, person wealth, decreased infant fatality Demographic Transition-a model of monetary and social change to clarify the suffering death and birth costs in industrializing nations

-stable preindustrial state of high beginning and loss of life rates in order to a stable post-industrial state of low birth and loss of life rates Demographic Stages:

Pre Industrial Stage- birth and death prices are excessive

Transitional Stage- death charge declines because of increased food production and improved amounts Industrial Stage- Birth price declines due to increased chances for women and access to contraception Post Industrial Stage- Labor and birth and fatality rates happen to be low

Would it be universal?

Provides occurred in Europe, U. S., Canada, Asia, etc . does not apply to most developing nations around the world, the change could fail in cultures. That place increased value upon childbirth or perhaps grant women fewer liberties Empowering Women and How that affects growth rates- females lack the info and personal flexibility to achieve the same power with men. 2 to 3 of people who simply cannot read, and 60% of these living in poverty are girls. Providing info on incentives, education, contraception, and reproductive medical this will reduce population progress rates. Sexual Ratios- naturally occurring sex proportions for humans slightly mementos males (100 female versus 106 males) Factors affecting population growth- rates of birth, death, and immigration Birth and immigration add individuals

Death and emigration remove people

Immigration and Emigration- asylum seekers flee their house country resulting from war, municipal strife, and enviormental wreckage.

-25 generator escape poor environmental circumstances

-movement causes environmental difficulties with no incentives to converse resources Dropping rates of growth just means the interest rate of maximize is slowing not that population is definitely falling Wealth Gap- wealthiest 20% work with 86% from the world's methods leaving 14%...
