WHAT ARE THE CHALLENGES?

REDUCING DISPARITY In 1900 approx. Two thirds of the 1.5 billion people on earth lived in LEDC’s today the figure is more like three quarters. 90% of babies born are born in LEDC’s. Of the 4.8 billion living there: 60% lack basic sanitation 30% without clean water 25% have little or no adequate housing 20% No access to health services

In 1900 approx. Two thirds of the 1.5 billion people on earth lived in LEDC’s today the figure is more like three quarters. 90% of babies born are born in LEDC’s. Of the 4.8 billion living there:

60% lack basic sanitation

30% without clean water

25% have little or no adequate housing

20% No access to health services

CUTTING CONSUMPTION More food needs to be produced – made worse by these people being born in LEDC’s LEDC’s struggle to produce the quantity of food Demand is increasing due to rise in number of households People living longer Family break up – Biggest in MEDC’s MEDC’s require more resources than LEDC’s

More food needs to be produced – made worse by these people being born in LEDC’s

LEDC’s struggle to produce the quantity of food

Demand is increasing due to rise in number of households

People living longer

Family break up – Biggest in MEDC’s

MEDC’s require more resources than LEDC’s

SAVING THE PLANET Effects on environment from growing need for resources Movement into marginal and wilderness areas Use of Non-renewable resources in MEDC’s Figure 1. Species Threatened with Extinction as a Percent of Total Number of Known Species

EASING THE FLOW Migration and its reasons have been around for millions of years often triggered by: Hazards Wars/ Conflict Overuse and abuse of environment Famine Oppression

Migration and its reasons have been around for millions of years often triggered by:

Hazards

Wars/ Conflict

Overuse and abuse of environment

Famine

Oppression

One in every 200 people is now a refugee Whilst migration could bring about more equality it is a hot political issue

SHRINKING THE FAMILY Though less to do with Geography than sociology it is important for the future of the planet BR fell by a third during the 20 th century DR fell by half Therefore NI remains high World needs lower fertility rates Population needs to be stabilised BR higher in LEDC’s Need for education, birth control and gender inequality

Though less to do with Geography than sociology it is important for the future of the planet

BR fell by a third during the 20 th century

DR fell by half

Therefore NI remains high

World needs lower fertility rates

Population needs to be stabilised

BR higher in LEDC’s

Need for education, birth control and gender inequality

ACTIVITY 1 Discuss in groups which is the most important in your eyes? And then rank them in the order of importance. Justify your conclusions What links are there between wealth and resource consumption How do MEDC’s adversely affect LEDC’s Suggest a recent event that has increased migration
