- extracts oil beneath sand
What are 3 main concerns with Fracking?
- Each well requires approximately 5-8 million gallons of fresh water which is then polluted and cannot be cleaned
- Ground water may be exposed to carciongens and radioactive gas
- Methane gas produced
What is an Electrosmog?
What could be the problem with an invisible wave?
