In Chapter 7 of the recently released Plan B 4.0: Mobilizing to Save Civilization, Lester Brown lays out the Plan B goals for eradicating poverty and stabilizing population. Behind the scenes are a number of datasets and graphs that delve deeper into the trends discussed in the chapter. Here are some highlights from the Chapter 7 data:
World population has grown steadily over the past half century, increasing from 2.5 billion in 1950 to a projected 6.8 billion in 2009. The United Nations medium fertility level scenario projects that world population will grow to 9.2 billion in 2050. Their high projection takes the world to 10.5 billion in 2050. Under their low projection, which assumes rapid reductions in fertility rates, population peaks at just over 8 billion in 2042, then begins to decline.
Though life expectancies around the world have increased in the past half century, large discrepancies remain among different regions. Overall, world life expectancy increased from an average of 47 years in the mid-twentieth century to 68 years today. While life expectancy in 1950 hovered around 40 years in both Sub-Saharan Africa and Asia, it has since increased far more rapidly in Asia, reaching 69 years, compared to 51 years in Sub-Saharan Africa. On a regional basis, the United States and Canada top the world with an average life expectancy of 79 years.

After months of resistance against emission reduction goals the Indian government now seems willing to take proactive measures to reduce carbon emissions.

In recent years there has been a growing concern over thresholds or tipping points in nature. In my latest book Plan B 3.0: Mobilizing to Save Civilization, I state that scientists worry about when the shrinking population of an endangered species will fall to a point from which it cannot recover. Marine biologists are concerned about the point where overfishing will trigger the collapse of a fishery.
We know there were social tipping points in earlier civilizations, points at which they were overwhelmed by the forces threatening them. For instance, at some point the irrigation-related salt buildup in their soil overwhelmed the capacity of the Sumerians to deal with it. With the Mayans, there came a time when the effects of cutting too many trees and the associated loss of topsoil were simply more than they could manage.
The social tipping points that lead to decline and collapse when societies are overwhelmed by a single threat or by simultaneous multiple threats are not always easily anticipated. As a general matter, more economically advanced countries can deal with new threats more effectively than developing countries can. For example, while governments of industrial countries have been able to hold HIV infection rates among adults under 1 percent, many developing-country governments have failed to do so and are now struggling with much higher infection rates. This is most evident in some southern African countries, where up to 20 percent or more of adults are infected.
A similar situation exists with population growth. While populations in nearly all industrial countries except the United States have stopped growing, rapid growth continues in nearly all the countries of Africa, the Middle East, and the Indian subcontinent. Nearly all of the 80 million people being added to world population each year are born in countries where natural support systems are already deteriorating in the face of excessive population pressure, in the countries least able to support them. In these countries, the risk of state failure is growing.

People often ask me what the environment has to do with poverty, and why communities of color are getting so active in the fight against climate change.
Today, we released a new video that says it all.

While aspiring to become an economic super power India must ensure that its industrial sector manages its resources in the most efficient manner and reduce its carbon footprint.

Food Not Bombs, a group dedicated to non-violent social change through feeding the needy, continues to find itself at the center of controversy as they enter their 30th year in existence.
Groups in New Mexico, Arizona, Florida, and Connecticut have run afoul of local laws that seek to stop them from handing out free meals in public places to those in need. Though all Food Not Bombs groups are independent, they share the common goals of feeding vegetarian meals to the hungry while also protesting war and poverty.
Food Not Bombs finds food that would otherwise be discarded - from restaurants, grocery stores, and other sources and prepares meals to anyone and everyone.

Rainfall patterns altered by climate change and worsened by inequity in the water distribution system has led to a water crisis in the central Indian state of Madhya Pradesh.
This has led to a spurt in water related violence and conflicts so shocking, we thought they were predicted to take place only in the next 50 years. The local incident mentioned in the news report above was one among many where a mob of about six people killed a family for illegally drawing water from the municipal supply even as onlookers rushed back and forth to collect water before the pipe ran dry.
The incident, which occurred in a below poverty line (BPL) settlement, is yet another validation of how climate change is having much more impact on the poor, especially in the developing world.
Haiti’s sorrowful rank as the poorest nation in the Western Hemisphere and one of the poorest in the world has been directly attributed to the degradation of Haiti’s natural environment (less than 1.5% of its original tree cover remains intact) as well as a lack of governance structures, underinvestment in social capital, obstacles to private investment, and a spiraling “poverty trap”.
