Sustainability Revolution: Earth, the planet we call home, is a complex system made of interdependent parts and pieces of life that are constantly changing. Earth’s planetary system has maintained a balance of dynamic equilibrium—it has been sustainable— since its beginnings about 4.5 billion years ago. This balance, however, has been progressively disrupted by us—humans— especially during the last few decades. Mother Nature has provided us with natural resources and the habitat for all species to sustain life on our planet. Since the industrial revolution, we have maintained a belief that these resources are infinite, and that economic growth and our attempts to improve our standards of living can continue forever. All forms of human economic
As small mobile groups of hunter-gatherers adopted a sedentary lifestyle, they mastered both agriculture and animal domestication. These small settled groups quickly evolved into cities and towns that encompassed the entire globe. Today the estimated population of the world is over 6.2 million people.1 As the population has grown, it has had several deleterious effects on the Earth. These include climate changes, the spread of diseases, declining food production, deforestation, and environment pollution (particularly air pollution). As people have become more conscious of these harmful effects, they have begun to devise strategies to combat this problem. Among the suggested responses include a switch to renewable energy, a call for zero population growth, and adopting sustainable agricultural practices.
The world is facing issues of overwhelming complexity and urgency. The challenge is to think globally and develop policies to counteract environmental decline and environmental collapse. Brown illustrates the economic future through an environmental perspective to develop a plan that will sustain civilization. Throughout the book, he concentrates on four major components that will head the world towards a brighter future. These include a massive cut in global carbon emissions, the stabilization of world population, the decrease of poverty, and the restoration of our planet’s diverse natural landscape. Brown presents the reader with very accurate arguments in World on the Edge however; he also makes some weak points that may not be the best plan to save the planet.
“Our global economy is outgrowing the capacity of the earth to support it, moving our early twenty-first century civilization even closer to decline and possible collapse (Brown, 3). This is the opening line of Lester R. Brown’s Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble. Brown goes on to support and emphasize this statement through the examination of the current state of our natural resources including the oil peak, water shortages, global warming and its effect on sea levels, shrinking forests, growing deserts, and extinction of plant and animal life. Brown even goes further to demonstrate how seemingly social issues, such as failing health and poverty are affecting the future sustainability of our environment. In a response to the concerns he raises, Brown also takes a look at the emerging solutions and alternatives that are currently being developed. He examines numerous options for each of the environmental issues discussed, and how these solutions can slow down, or even bring to a halt any more harm to our environment. In the final portion of this book, Lester R. Brown takes a look at how we can begin making changes in the way our society is designed and the simple adjustments that can shift our economy towards creating a more sustainable environment. While the necessary changes may seem grandiose, Lester Brown does a successful and inspiration job of demonstrating how change can only happen if it begins with each one of us.
The demands of increasing population magnify demands for natural resources, clean air and water, as well as access to wilderness areas. In the future, when there are not enough resources to go around, we will see significant scarcity, and a backlash of poverty. A number of problems lie behind scarcity and poverty. Ultimately, our own numbers, and the lifestyles many of us choose to live, drive all the critical issues we confront. Left unchecked, the combination of population growth and consumption- along with increasing inequity between rich and poor individuals and nations-will soon threaten not only the well-being, but even the lives of a majority of people on this planet.
Over the past years most individuals have become acutely aware that the intensity of human and economic development enjoyed over the 20th century cannot be sustained. Material consumption and ever increasing populations are already stressing the earth’s ecosystems. How much more the earth can take remains a very heated issue. Here a look at the facts sheds some very dark light. In 1950, there were 2.5 billion people, while today there are 5.8 billion. There may well be 10 billion people on earth before the middle of the next century. Even more significant, on an ecological level, is the rise in per capita energy and material consumption which, in the last 40 years, has soared faster than the human population. “An irresistible economy seems to be on a collision course with an immovable ecosphere.” Based on these facts alone, there is grave reason for concern.
"The science of human sustenance is inherently a social science. Neither physics nor chemistry nor even biology is adequate to understand how it has been possible for one species to reshape both its own future and the destiny of an entire planet."(Overpopulation Is Not the Problem By Erle C. Ellis Sept. 13, 2013) Modern technology gives us the opportunity to start an Environmental Revolution. This revolution consists of innovative green technology. Humanity has already taken a step toward this change implementation of solar powered energy and smart cars are only a few examples. The goal that plans to be reached are more efficient advancements of technology, smarter planning both in urban and regional areas as well as policies that support industrial
Humans have become a threat to our own way of life by consuming more resources than needed, blind to the consequences that we may face in the future. As of 2016 the world population is at 7.4 billion and it is estimated to be at 11.2 billion by the year 2100. However 10 billion is the maximum population that can be sustained in terms of food security, only one of the many factors to global sustainability. Due to the fact that human consumption exceeds the amount of resources available, the United Nations “recognizes that eradicating poverty is the greatest global challenge” in A/RES/70/1. Sustainable development is not only required to fulfill the necessities of the present but to guarantee the capability for future generations to satisfy theirs.

According to the International Institute for Sustainable Development, sustainable development is defined as development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. If we follow this definition, it becomes easy to see that the vast majority of the “developed” world has not, and is not developing sustainably. The idea of sustainable development requires us to consider how our action of developing will affect other countries, and future generations. Many people believe in “the butterfly effect”, where the flapping of a butterfly’s wings in one part of t...
