Geothrix Fermentans
Geothrix fermentans is a rod-shaped, anaerobic bacterium. It is about 0.1 µm in diameter and ranges from 2-3 µm in length. Cell arrangement occurs singly and in chains. Geothrix fermentans can normally be found in aquatic sediments such as in aquifers. As an anaerobic chemoorganotroph, this organism is best known for its ability to use electron acceptors Fe(III), as well as other high potential metals. It also uses a wide range of substrates as electron donors. Research on metal reduction by G. fermentans has contributed to understanding more about the geochemical cycling of metals in the environment.

Fee and Dividend
Fee and Dividend or Carbon Fee and Dividend (CF&D) is a market-based mechanism for reducing the carbon emissions that help to drive anthropogenic climate change. Carbon Fee and Dividend begins with levying a progressively-rising tax on carbon-based fuels, then returning some or all of the revenue to the public as a regular energy dividend. This is intended to incentivize a shift to low-carbon energy while protecting consumers from any increases in the costs of carbon-based fuels. Designed to maintain or improve economic vitality while speeding the transition to a sustainable energy economy, Carbon Fee and Dividend has been proposed as an alternative to emission reduction mechanisms such as complex regulatory approaches, cap and trade or a straightforward carbon tax. The method has been compared to wealth redistribution legislation that was used during the Great Depression.

Mekong
The Mekong, or Mekong River, is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the sixth longest in Asia. Its estimated length is 4,909 km (3,050 mi), and it drains an area of 795,000 km2 (307,000 sq mi), discharging 475 km3 (114 cu mi) of water annually. From the Tibetan Plateau the river runs through China , Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia.
