Petroleum -- Disadvantages

Oil does have advantages but also disadvantages too. Petroleum is nonrenewable. The estimated end is to be in 40-60 years. Industries spend billions of dollars on technology to find petroleum in the ocean. Also, spills on the sea devastate sea life. Two oil spills happened recently, once in 1989 when the Exxon Valdez spilled into Alaska's water and later a worse oil spill happened. In 2010, when the Deepwater Horizon blew up in the Gulf of Mexico, it leaked even more oil than the Exxon Valdez. Both spills killed a lot of marine life and caused a lot of oil to be lost.

When people drill wells, only forty-four out of one hundred wells get petroleum. If the well found petroleum, workers can only get a small amount of petroleum. The workers know there's more, but cannot get it. The workers usually recover 1/3 of a barrel of petorleum. In fact, it might take decades to get 50% of petroleum in one place. There are many hazards of drilling too, such as huge pressure in rocks may blast through pipes and leaking storage tanks can pollute groundwater and cause noxious fumes.

Noxious fumes

Here are some noxious fumes and the effects they cause.

  • Carbon dioxide - causes global warming

  • Sulfer dioxide - acid rain, respiratory illness, and heart disease

  • Nitrogen oxides - contribute to ground level ozone, which damages lungs

  • Particulate matter (P. M.) - asthma, chronic bronchitis, lung cancer, and emphysema

  • Lead and air toxics - severe health impacts, and probable carcinogens


Cars produce air pollution. In fact, exhaust fumes from vehicles contain chemicals which turn into smog.

Oil rigs

Oil rigs are isolated and their work

with oil involves many hazards such as explosions. Fierce storms, fires, and shipping accidents may damage

oil rigs.
