This is the Earth at nighttime. Notice that North America, mainly the USA is using massive power 24 hours a day, 365 days a year. Next is Western Europe, than Japan. There are major cities around the globe that also have this intensity of light all night.
The all-night-long power grid represents a direct relationship with industrial activity, automotive activity, and any other activities that use electric power. All these activities are not pretty Christmas lights for the kids ... or cool light shows for the stoners... they represent "cancer" to the planet Earth. And present the highest levels of heat trapping gases: The USA being the major culprit.
The best analogy is, the area with the high levels of light indicates spreading cancer - which is harbinger of the impending doom of the ecosystem, all its species, (e.g. the worlds frogs are all dying off, they are the indicator species of eco-health). Ultimately the major species that's causing it, the apex predator, will die in the end ... humans.
Sadly, areas like India are starting to become lit up like Europe and the USA. Not even close yet to the brightness and intensity of the USA but one day if they stay on this path it will be. Post-industrial Human activity is the root of the disease. Western countries are the ones most responsible for engineering, marketing, and spreading the industrialization.
If you look around at the rest of the planet that is mostly in the dark at night you can see it's in areas like Africa, South America, and Eurasia. The all-night-long power-sucking vampires of the planet are impoverishing the Earth. The party won't last my friends. You think technology will save us? The Earth laughs in our faces. We are at a tipping point in human history. All the people who think of themselves as the “have-mores” and laugh at the poor, “have-nots” are the true cancers of this world. The planet and nature has no ability though to discriminate between rich and poor individuals or nations. Nothing you own will save you; not your houses, your SUV's, your bank accounts, your guns, your medications...nothing. Once this ship tips, the party is OVER.
You are either a part of the disease or a part of the solution. You either deny the truth or accept this disease exists and start doing something about it. Our kids will have nothing but a world sucked dry by our slothful ways, greedy soul, and mental apathy.
