Ban Hydraulic Fracking (Aff.) Only2% of the U.S. natural gas supply in 2000; it was 37% in 2012. This U.S. energy boom comes largely thanks to the technology of "fracking," or hydraulic fracturing, coupled with horizontal drilling methods that allow for much faster, more efficient extraction of oil and natural gas. But the question is, is fracking justified? I stand here today to state that it is not. Therefore, I asked that the house vote in affirmation to this bill.

Chapter 25- Origin of life on earth The earth is estimated to have formed about 4.6 years ago condensing from a cloud of dust and rock. For the first few hundred millions years the Earth was being bombarded by huge chunks of rock and ice. The collisions created enough eat to vaporise the adavible water and prevent seas from forming. The early earth had a reducing atmosphere (electron adding) and there was no oxygen in the atmosphere, and as a result there was no need for an ozone layer to protect the earth from high levels of UV radiation.
