Crop Circles
Crop Circles are geometric patterns that appear mysteriously in crop fields. The crop is not cut, but is usually laid flat and most often swirled into an attractive floor pattern. Most patterns appear in cereal crops such as wheat and barley, but circles have been known to occur (in lesser numbers) in oilseed rape, maize, linseed, grass and even borage – to name a few.
There are many theories about who or what makes the crop circles. Whirl-winds, earth energies, extraterrestrials and human hoaxers to name but a few. What makes the crop circle subject so fascinating is that anyone and everyone can take part in the search for answers. There has been some very interesting scientific work carried out on the crop and soils from the circles which should be investigated by all those with an interest in the phenomenon. Much the same goes for the ultimate meaning behind the designs, there has been some fascinating research into the geometry and mathematics of the crop circle designs and shapes, which suggest that the designs are not arbitrary or meaningless, but quite the opposite. People have connected the circles to subjects as diverse as star constellations and quantum physics to alchemy and spirituality. Some of the most fascinating research is concerned with shape and vibration (Cymatics) and the collective unconscious.

just reposting this from reddit, it's not really worth watching but he thinks the reason for the low number of formations nowadays is the low interest in the public's mind and the constant debunking and lack of effort to look deeper into the anomalous aspects of crop circles.
So basically "people stopped giving them attention, so people stopped faking them". Crazy to see that some conspiracy's follow supply and demand curves.....
