For the record, I do realize that I should probably wait until I park to think about things like this.And being the biology nerd that I am, I thought about how this theme applies to the natural world as well.
Here, I'll do it for you.
I could go on and on about how variety is better for everything (diet, wardrobe, genetics, throw pillows, race) and how much evidence there is for the interconnectedness of all things (religion, weather, overfishing, movie remakes, non-native species, pollution, language), but I won't do this to you. This post is already too long.
Interconnectedness means our mistakes have ripple effects, yes, but it also means that we are all in this together. "This" being existence and prosperity. The togetherness spans all barriers--race, religion, nationality, species. Our planet is a global community of countries, peoples, and ecosystems. The more we realize this, the more we will help each other, and in turn help ourselves. Group hug!
