Understanding nature leads to respecting it. It also helps when you don't fear it anymore, and modern technology definitely enables humans to stop fearing nature. And thus, as more and more people start looking at breathtaking waterfalls, mountains and beautiful animals in their natural habitats (you know, since they're so rich they have lots of time on their hands), the concept of conserving this nature starts to gain momentum.
Conservation is one of a series of concepts which dedicates to nature. And it benefits a society greatly, especially one which is more culture-oriented. It unlocks the Naturalist, a special unit whose task is to wander the wild parts of your empire and found National Parks, where your citizens may go and admire wild nature. It also gives new importance to Woods, increasing the Appeal of these that have been there since the beginning of time, and teaching the Builder to plant new woods. Additionally, the Walls that have protected cities for centuries start to become more culturally than militarily significant, providing Tourism that increases based on how advanced they are. Finally, these important developments cause widespread admiration for your civilization among your diplomatic peers, and you gain 3 Envoy Envoys.
The idea of conservation of natural resources can be traced to the work Sylva, or a Discourse of Forest-Trees, presented by John Evelyn to the Royal Society in 1662 AD. Timber resources in England were seriously depleted – thanks to all those ships, buildings and bridges – and Evelyn argued that cutting should be managed and trees replanted in logged areas. No one paid any further attention to the environment, other than exploiting it, until the Progressive Age when some folks sought to convince other Americans that it was their civic duty to preserve unspoiled the land, water and wildlife for future generations. Romantics such as Henry David Thoreau idealized nature, even as pragmatists such as Gifford Pinchot (first head of the U.S. Forestry Service) sought ways to insure that renewable resources would remain renewable … to keep America strong and the economy expanding.
Even as American cities were becoming more crowded, as the Western frontier was disappearing, as “nature” was being commercialized, and as the working man had more disposable income, leisure and conservation came together as more and more people took up hiking, camping, bird watching, and other outdoor recreations. With general support from the citizens, the U.S. Congress passed landmark legislation establishing Yellowstone Park in 1872, Yosemite National Park in 1890, and finally creating the National Park Service in 1916. Soon the individual states were creating parks and preserves all over the place, and establishing policies to protect fish and game from wholesale slaughter (rather too late for the poor passenger pigeon).
Although efforts to protect the environment sometimes produced more problems (such as the elimination of predators in parks leading to mass die-offs), other developed nations soon leapt onto the conservation bandwagon as well. It would be some decades before developing countries would join the movement … being rather more concerned with pragmatic issues such as industrializing, avoiding famine, and raising the standard of living for their citizens.
