@david-coxiii, @samantha-ocon I know of a mineral collector who did some lapidary work and had used a wet diamond saw. He breathed the water spray that comes off the saw over many years. This spray contains fine rock dust. He now has a serious lung disease.

6 months ago6 months agoMy thoughts kind of related to the decline of sharks world wide. Seems like many species of fish are overfished as well. If sharks could not maintain their diet (at whatever level), then a constant replacement rate of teeth could result in a degradation to the shark’s body over time.

6 months ago6 months agoAmazing sharks replace their teeth weekly. No wonder they need to eat so much considering the mass of the tooth loss. I wonder if the replacement rate would change depending on their diet?
-
Studies with captive sharks in aquariums show that they actually don’t eat a lot, a few pounds a week. Now warm blooded sharks (like the Great White and mako) are more active and have a higher metabolism, but even then they will gorge themselves and then not eat for a lengthy period of time afterwards.

9 months, 1 week ago9 months, 1 week agoIt really shows the complexity of earth systems. Think about the sub categories and ranges of potential values for each (not to mention the ability to measure those values accurately) of these cards’ topics. No shortage of things to study.
