The Republic of Leaf Greens is a colossal, safe nation, ruled by Treehugger with an even hand, and remarkable for its smutty television, restrictive gun laws, and devotion to social welfare. The compassionate, democratic population of 6.764 billion Leaf Greensians are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

It is difficult to tell where the omnipresent, socially-minded government stops and the rest of society begins, but it juggles the competing demands of Environment, Education, and Administration. It meets to discuss matters of state in the capital city of Treehouse. The average income tax rate is 94.8%.

The Leaf Greensian economy, worth 393 trillion Climate Credits a year, is driven almost entirely by government activity, with private enterprise illegal. The industrial sector is solely comprised of the Basket Weaving industry. Average income is 58,140 Climate Credits, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

The weather in Treehouse is always 'pigeons with a chance of droppings', toast never burns but always has a weird chemical taste, sushi is sold on the black market, and Leaf Greensians have replaced bears in a popular idiom. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Leaf Greens's national animal is the Tree, which frolics freely in the nation's many lush forests, and its national religion is Environmentalism.

Leaf Greens is ranked 15,396^th in the world and 103^rd in Forest for Most Extensive Public Healthcare, scoring 6,070.22 on the Theresa-Nightingale Rating.
