Key Links Between Consumption, Climate Change

The world's population is expected to be ten times larger by 2050 (roughly 10 billion) than it was for most of the 19th century (around 1 billion). Future population size in poor countries will have significant consequences for health and the environment, say the authors. Improved sanitation, nutrition and healthcare are allowing more children to survive into adulthood, whilst a reduction in fertility rates is leading to an aging population.
When implemented with other social and economic improvements, family planning is one of the most effective ways of managing increases in population growth and for delivering extensive health benefits, in both developed and poor countries. Access to family planning has significantly reduced maternal and infant deaths, although there remains a considerable unmet need for family planning, say the authors.
Population, health and climate change
Although population is an important factor, demographic trends are more significant for climate change than total population, says the review.
Consumption patterns, together with aging and urbanization in some countries, have bigger implications for health and the reduction of carbon emissions than the total number of people in the world.
The world's poor have contributed little to climate change and yet will experience the biggest effects
of course.
