The air is full of carbon dioxide and other pollutants;
The ocean is emptying;
We have observed record setting harvests over the last few years, and yet chronic hunger persists and has recently been increasing;
The planet is experiencing the 6th great extinction;

All of these are the result of human activity.

This evidence illustrates that we have not responsibly managed, neither through governance nor technology, our environmental resources. In the absence of finding a sustainable relationship with our ecosystem, we might conclude that we have reached Earth's carrying capacity.

Human waste may be a topic that people generally do not or prefer not to think about. However, its capture and disposal (often referred to in terms of sanitation) play a vital role in human health and development. The importance of sanitation as a basic human need has made it an international development priority and a key target in the United Nations Millennium Development Goals. Even though since 1990 the percent of the global population with access to improved sanitation has increased (see Figure 1.), lack of improved sanitation still threatens human health and development particularly in developing regions of the world.

The number of piracy attacks reported this year have already far exceeded those of last year. According to the International Chamber of Commerce (ICC), as of September 23, 2009, 294 piratical incidents have been reported, with 97 occurring in the Gulf of Aden and 47 off of the remaining coasts of Somalia. Figure 1 shows the placements of pirate attacks within the Gulf of Aden from July to September, 2009.
