You are undoubtedly familiar with the statement, Think Globally, Act Locally. Quoting from the Wikipedia (Wikipedia, 2019b, link):
"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.
