At the rate things are going, the Earth in the coming decades could cease to be a “safe operating space” for human beings.
We have already crossed four “planetary boundaries.” They are the extinction rate; deforestation; the level of carbon dioxide in the atmosphere; and the flow of nitrogen and phosphorous (used on land as fertilizer) into the ocean. Scientist shown human activities — economic growth, technology, consumption — are destabilizing the global environment,”
“What the science has shown is that human activities — economic growth, technology, consumption — are destabilizing the global environment,”
"Human security will be progressively threatened as the climate changes," the UN's Intergovernmental Panel on Climate Change (IPCCC) warned in its overview report. The Pentagon agrees. "Rising global temperatures, changing precipitation patterns, climbing sea levels, and more extreme weather events will intensify the challenges of global instability, hunger, poverty and conflict,"
Scientists estimate that humans will consume twice as many resources as the planet can support by 2050. At the rate things are going, the Earth in the coming decades could cease to be a “safe operating space” for human beings.
Africa Will Starve and Asia Will Drown in 30 Years Due to Climate Change
People in Asia and the Pacific are four times more likely to be affected by natural disaster than in Africa and 25 times more than in Europe or North America?
Global warming could cause an 18 percent drop in world food production by 2050
15 Cities Threatened by Climate Change
The World Bank alarm bells are just the latest to sound about the havoc climate change and man-made global warming will cause to the planet.
The World Health Organization predicts that climate change will cause 250,000 additional deaths per year around the globe between 2030 and 2050, primarily from malaria, diarrhea, heat exposure and malnutrition.

Human Ecology Foundations was a required course at the time for all students in the College of Education and Human Ecology. A diverse population, the students came from Human Development & Family Science, Clothing & Textiles, and Family Resource Management. There were more than 15 majors within those departments and this course was an overview of all the fields represented by the college. Needless to say, this made teaching this course challenging. More challenging to me, however, was teaching the material 4 times a year and keeping it fresh and interesting for 360 students per term. In a large class, bored students sleep, study for other classes, don’t show up. This lecture used to be the worst one for my predecessor. I taught it from the perspective of the world events happening around the seminal events of each of their majors. It is my all-time favorite lecture and was a favorite with students, too, according to their course reviews.

Ecology Against Capitalism by Christopher PickeringRatbag Media
Crisis NOT caused by: human nature, modernity, industrialism, economic development
Problem = social relations of CAPITALISM
Environmental problems can be overcome without abandoning prospect of human progress
Fundamental social change to make sustainable relations to environment possible
Presentation prepared for a series of lectures on Environmentalism for PS 240 introduction to Political Theory at the University of Kentucky, Spring 2007. Dr. Christopher S. Rice, Instructor.
This is the 7th lesson of the course - Foundation of Environmental Management taught at the Faculty of Social Sciences and Humanities, Rajarata University of Sri Lanka
This is the 10th lesson of the course 'Poverty and Environment ' taught at the Faculty of Social Sciences and Humanities, Rajarata University of Sri Lanka
2. Growing rapidly Tripled in size in about 70 years Est. size to day 6 billion+ (approx. 2 billion in 1930) Human Population
3. Problems cause by humans Thinning ozone layer – ozone layer protects living things from ultraviolet radiation form the sun Climatic changes Greenhouse effect: insulates earth from the deep freeze of space; keep Earth warm Caused extinction of other species – extinction rate higher today than at any other time Increased pop. requires increasing amts. of food, energy, space – greater share of Earth’s resources will be required Burning Fossil Fuels for energy – releases carbon dioxide; excess CO2 traps too much heat in Earth’s atmosphere
4. Human Population Growth Improved by agricultural development, hygiene, diet, and economic conditions improved Today, population growth is faster in less-developed countries and slower in more developed countries
5. Population Dynamics Changes in size and composition over time Measure include: birth rate - number of births over time (in US it is 4 million per year) death or mortality rate – number of deaths in a period of time (in US it is 2.4 million per year) life expectancy – how long an individual is expected to live (1996: in US it was 72 yrs. for a man and 79 for a woman)
6. Population Growth Rates Amount of change within a population’s size in a given time Four factors that affect growth rates: Birth Death Emigration – movement out of a population Immigrations – movement into a population Demographers – scientists who study populations dynamics Birth rate – death rate = growth rate
7. Carrying capacity of a population is the number if individuals the environment can support for an indefinite period of time. Populations fluctuate over time do to environmental changes. Small populations are less able to rebound from environmental changes. They are more likely to experience inbreeding and their genetic diversity is low.
8. Population Growth Curves Linear – growth occurs along a straight line NOT what we see w/ populations of organisms
9. Population Growth Curves Exponential – as population gets larger, it grows faster (population explosion) “J shaped”
10. Predator-Prey Predator-Prey – (predation is density dependent limiting factor) When population grows beyond carrying capacity of environment, density-dependent Limiting Factors reduce population population grows/shrinks cycles
11. Carrying Capacity What is seen in most populations of organisms. Population growth is limited by factors in the environment such as food supply or habitat.
