I've been doing a lot of learning and research (for reasons I won't go into), but this included an Astronomy course, seismic studies (yes, many earthquakes ARE predictable), learning all the non-Euclidean math required, and an eye-opening amount of study around the subject of cycles (like the 26,000+ year "Grand Cycle").
The reality is that the Earth IS changing and will continue to do so regardless of what people do (key part Sparky!). There are always around 18 volcanoes currently erupting (not just "active") and one big eruption can dwarf what humans can do. In about 8,000-12,000 years, the area where the Sahara desert currently is, will, once again, be a tropical rain forest area (larger than the Amazon is now) with some of the largest fresh-water lakes on Earth. These both are still there, just buried under all that sand! Recent satellite imaging has not only discovered this, but lots of other signs of previous civilizations (which include pyramids - no, the Egyptians did not build these). It was discovered by one of the space shuttles that there are entire forests flash-frozen under miles of ice in the Antarctic too, and most people already know that the vast majority of the Northern Hemisphere was covered in ice just a few thousand years ago.
However, those who crave power and money will ALWAYS use any situation they can, so what better way than to con people into giving up their freedoms and money than a campaign to "save the planet" for future generations?
P.S., IBTL! ?
