Relative dating for fossils

Fossil fuel mining and oil production can and has caused irreparable damage to our environment.

Fossil fuels exist, and they provide a valuable service.

While they collect the vast raw energy provided by water currents, they also create environmental hazards such as silt buildup.

They are also significant barriers to fish, such as the salmon of the Pacific Northwest, which must migrate in order for the species to survive.

The Hoover Dam is a major source of energy for the southwestern US.

Despite the promise of alternative energy sources — more appropriately called renewable energy, collectively they provide only about 7 percent of the world’s energy needs (Source: Energy Information Agency).The total world energy demand is for about 400 quadrillion British Thermal Units — or BTUs — each year (Source: US Department of Energy). A BTU is roughly equal to the energy and heat generated by a match.Oil, coal and natural gas supply nearly 88 percent of the world’s energy needs, or about 350 quadrillion BTUs.Coal, oil and natural gas are the three kinds of fossil fuels that we have mostly depended on for our energy needs, from home heating and electricity to fuel for our automobiles and mass transportation. They are limited in supply and will one day be depleted. Fossil fuels formed from plants and animals that lived hundreds of millions of years ago and became buried way underneath the Earth’s surface where their remains collectively transformed into the combustible materials we use for fuel.In fact, the earliest known fossil fuel deposits are from the Cambrian Period about 500 million years ago, way before the dinosaurs emerged onto the scene.

Certainly, if there were a way that fossil fuels can be mined and used in ways that do not harm our ecology, then everything will be okay… What makes our world perfect is that, it really isn’t perfect according to definition.

  1. Anoche querías ir a dormir conmigo, como siempre desde que naciste, aunque si ahora tenemos menos ocasiones porque alguna vez coincide con que estoy durmiendo a Orlando y entonces vas con papá.
