It's high acidity degrades soil to the point where it cannot support any type of plant life. Trees in forests are killed over long-term exposure.

These will receive an excess of water, causing other problems in the hydrologic cycle. This in turn causes a chain reaction of death among our forests. Some regions are more susceptible to . They don't have enough Alkaline so .....

Electronic rust prevention is another method used to prevent rust using one of two technologies; either Impressed Current or Sacrificial Anode. Impressed Current units are extremely effective in dry conditions but ineffective in the wet. Sacrificial Anode units, like those used on ships, are very effective in wet conditions but cannot inhibit rust in dry conditions. Obviously vehicles ex .....

years, in short, the duck population was reduced by almost one third, showing
the drastic toll hunting is taking on our wildlife. If we assume that other
