In the soil occur natural metals which are toxic to all life. These toxic metals are: Aluminium, Arsenic, Beryllium, Cadmium, Copper, Lead, Mercury and Nickel.
Under normal circumstances, they are quite harmless as they are bound into the geological structure of the earth; however, they are released in the presence of acid and then find their way into our natural drinking water resources.
Acid rain is already causing this effect to some degree and many countries that rely on ground water are now finding them tainted with Arsenic, however, in the very near future, given the amount of Nitrogen Oxide, Sulphur Dioxide and the massive amounts of Carbon Dioxide particularly from the burning vegetation as a result of the burning hail, acid rain will be strong enough to release these toxic metals in a big way.
Natural water resources will become contaminated with toxic metals and the acidic water will taste bitter. Drinking the water will cause; Headaches, Nausea, Vomiting, Hallucinations, Kidney Failure, Liver Failure, Coma and Death.
Arsenic poisoning causes sores as seen in the above picture.
Toxic metals can also cause deformities in wildlife that lay their eggs in the soil. This is a key factor in Event 5 The Locusts Of Revelation 9.
Revelation Chapter 8 Verse 10 &11 says:
The third angel sounded his trumpet, and a great star (Angel) blazing like a torch, fell from the sky on a third of the rivers and on the springs of water. The name of the star (Angel) is Wormwood. A third of the waters turned bitter, and many people died from the waters that had become bitter. (NIV)
Wormwood is a plant which is widely grown throughout the Middle East. It has a very bitter taste and Ingesting even small quantities can cause Headaches, Nausea, Vomiting, Hallucinations, Kidney Failure, Liver Failure, Coma and Death.
