"Think globally, act locally" To put it simply, it means: Be open minded about learning about issues, cultures, and events around the world, and make use of this knowledge to improve your local area, hometown, or country. So for example, I could say I traveled to Japan and noticed how clean the streets were over there and how people generally picked up after themselves. In turn, when I am back here in America, I'll recycle, pick up trash when I see it, and try to improve the environment based on my experiences abroad. Again, it's more of an adage that emphasizes "learn from others, to improve yourself / your home." Hope that helps!
