“The debate regarding which individual factor, among the three key factors producing the environmental crisis, causes more damage - the size of the human population on the planet, excessive consumption of resources or unequal/ unjust distribution of resources among countries [the wealthier countries consume much more resources than poorer countries] - is like a debate about which contributes more to a triangle, the base or the ribs of the triangle. You can not separate the three factors. If we analyze the numbers over a relatively longer time interval, we will conclude that the size of the population has a bigger impact than consumption. On the other hand, consumption and unequal distribution are also important aspects. If we do not change these three factors all at the same time, the quality of our life will change dramatically. Today humanity is delivering a serious blow to nature, but it is clear that nature will deliver the final blow.”

“We can no longer afford indifference to suffering outside our borders; nor can we consume the world's resources without regard to effect. For the world has changed, and we must change with it.”

Barack Obama (1961) 44th President of the United States of America

2009, First Inaugural Address (January 2009)

“If we can stop, listen, and think about what others are seeing in us, we have a great opportunity. We can compare the self that we want to be with the self that we are presenting to the rest of the world. We can then begin to make the real changes that are needed to close the gap between our stated values and our actual behavior.”

Marshall Goldsmith (1949) American author of leadership and management literature

“No system can ever relieve us of our personal responsibility, and it is essential that we all recognise the need to change the way we live.”

“But why must the system go to such lengths to block our empathy? Why all the psychological acrobatics? The answer is simple: because we care about animals, and we don't want them to suffer. And because we eat them. Our values and behaviors are incongruent, and this incongruence causes us a certain degree of moral discomfort. In order to alleviate this discomfort, we have three choices: we can change our values to match our behaviors, we can change our behaviors to match our values, or we can change our perception of our behaviors so that they appear to match our values. It is around this third option that our schema of meat is shaped. As long as we neither value unnecessary animal suffering nor stop eating animals, our schema will distort our perceptions of animals and the meat we eat, so that we can feel comfortable enough to consume them.”

“What we do need to worry about is the possibility that we will be reduced, in the face of the enormities of our time, to silence or to mere protest.”

“Because we are the cause of our environmental problems, we are the ones in control of them, and we can choose or not choose to stop causing them and start solving them. The future is up for grabs, lying in our own hands. We don’t need new technologies to solve our problems; while new technologies can make some contribution, for the most part we "just" need the political will to apply solutions already available.”

“Traditionally, the cost of change curve said that if we detect the need for a change early, it costs less to make the change than if we detect the need late. I tackled that curve by saying, let's almost intentionally make mistakes so we can practice correcting them. That practice will help reduce the cost of making changes late.
Our feeling was that the limiting factor on any change was not when it was done, but how much thinking was required.”

“There are times we don't want to hear about the need to temper our best hopes in order to achieve our most vital security. But we still need to do it. Before we can triumph, we must survive. Before liberty can prevail, the possibility of liberty must be preserved.”

“We need to develop within our children and young people the capacity to respect the cultures and beliefs of the different groups that make up our society; and we need to develop the resolve to treat each other justly. Secondly, we must eliminate, so far as any society can, the under-achievement of many of our children and young people from all sections of the community. We need to raise the performance of all pupils and to tackle the obstacles to higher achievement which are common to all. But we also need to tackle those special factors which additionally may contribute to the under-achievement of many members of our ethnic minorities.”
