What you do affects the oceans and entire planet.
This is a watershed.
A watershed, as defined by the United States Geological Survey, is: “the area of land where all of the water that falls in it and drains off of it goes to a common outlet.”
Essentially, a watershed is an area that drains to a common body of water — Rain, to runoff, to creeks and rivers, to lakes, and eventually the ocean. Everything within a watershed — industrial activities, farms and agriculture, roadways and trash — accumulates and drains into the ocean.
Watersheds can be big ~ enormous ~ meaning that even if you live hundreds of miles away from the ocean, your actions matter.
For example, here is a picture of the Mississippi Watershed.
The Mississippi Watershed is enormous. Including nearly half of the United States and even parts of Canada, water collected throughout this region eventually travels south to the Gulf of Mexico, where it drains into the ocean.
But it doesn’t stop there… From the Gulf of Mexico, waste/agricultural runoff/industrial byproducts are transported by currents throughout the rest of the ocean/world.
So… even if you are so landlocked, that you’re landlocked by landlocked states, your daily actions impact the ocean. It’s not immediate, and you may never see it ~ but watersheds serve as an important example of how we fit into a bigger world, & our responsibility to think consciously about our daily actions & decisions.
