The phrase "Think globally, act locally" or "Think global, act local" has been used in various contexts, including planning, environment, education, mathematics, business and the church.
"Think globally, act locally" urges people to consider the health of the entire planet and to take action in their own communities and cities. Long before governments began enforcing environmental laws, individuals were coming together to protect habitats and the organisms that live within them. These efforts are referred to as grassroots efforts. They occur on a local level and are primarily run by volunteers and helpers.
"Think Globally, Act Locally" originally began at the grassroots level, however, it is now a global concept with high importance. It is not just volunteers who take the environment into consideration. Corporations, government officials, education system, and local communities also see the importance of taking necessary actions that can impact positively the environment.
Warren Heaps states, "It's really important to recognize that markets are different around the world, and company compensation programs should reflect a balance between global corporate philosophy and local practice and culture".
The original phrase "Think global, act local" has been attributed to Scots town planner and social activist Patrick Geddes, a Scottish biologist, sociologist, philanthropist and pioneering town planner. Although the exact phrase does not appear in Geddes' 1915 book Cities in Evolution, the idea (as applied to city planning) is clearly evident: "'Local character' is thus no mere accidental old-world quaintness, as its mimics think and say. It is attained only in course of adequate grasp and treatment of the whole environment, and in active sympathy with the essential and characteristic life of the place concerned." Geddes was also responsible for introducing the concept of "region" to architecture and planning. He has made significant contributions to the consideration of the environment.
