How does crude oil replenish itself?

Answer 1

it takes millions of years,too long for us to care,when we pump it all out it's gone..............tom

Answer 2

There is strong evidence that concentrations of CO2 in the atmosphere are related to global temperatures. Evidence is from a variety of sources and reflects relationships between gas concentrations and temperatures over a wide range of time scales. Whenever there is an increase in CO2 concentrations there is also an increase in the temperature of the air and in global precipitation.

Since monitoring began in the 50s, fossil fuels burning was found to be the major contributor of the increase in CO2 concentrations in the atmosphere and, therefore, of the increase in air temperature causing global warming of the planet. Concentrations have increased approximately 21% since 1958. The average rate of increase since 1958 has been about 0.4%/year, which is an absolute increase of about 1.5 parts per million by volume (ppmv). In year 2005, the predicted value will be 402 ppmv. CO2 persists for a long time in the atmosphere and has a residence time in the order of decades to a century.

While Canada contributes only about 2% of total global GHG emissions, it is one of the highest per capita emitters, largely the result of its size, climate (i.e., energy demands), and resource based economy. In 1990, Canadians released 21.9 t CO2 eq of GHGs per capita. Over the 11-year period from 1990 to 2001, this has increased to 23.1 t CO2 eq of GHGs per capita.

Carbon Dioxide is, by far, the largest contributor to Canada's GHG emissions. The following figure shows how little the percentage contributions of the 6 GHGs has changed between 1990 and 2001. CO2 has only changed in proportion from 77.7% of emissions in 1990 to 78.9% in 2001.

Per capita emissions of greenhouse gases (GHGs) in British Columbia decreased by 6.3% between 1990 and 1999. Total emissions increased by 20% over the same time period. The increase in total GHG emissions was partly due to population growth, but increased emissions from the transportation sector played the largest role. The transportation sector is the single largest source of GHG emissions in British Columbia, producing 42% of the total. If current trends continue, the increase in British Columbia’s total GHG emissions from 1990 to 2010 is expected to be 38%, one of the largest predicted increases in Canada. In 1999, total GHG emissions were 63.5 megatonnes of carbon dioxide equivalent, an increase of 10.8 megatonnes or 20% since 1990. Population growth accounts for part of the increase in total GHG emissions; however, the increase in emissions from the transportation sector exceed the population growth rate.Transportation is the single largest source in the province, accounting for 42% of the total emissions. GHG emissions are strongly influenced by energy prices and economic activity. A decrease in GHG emissions in the early 1980s (not shown above) was largely attributed to increasing energy costs and the economic recession.

The use of fossil fuels in transportation, industry, heating and power generation throughout the world has increased steadily over the past 40 years. This has resulted in increases in greenhouse gas emissions, shown here as carbon dioxide levels (the bars on the chart).

Greenhouse gas emissions have increased at the same rate as the overall world economic production, measured by the Gross World Product (GWP). The GWP reflects the increase in worldwide industrialization and human population levels.

CO2 concentrations in the atmosphere have been measured at an altitude of about 4,000 meters on the peak of Mauna Loa mountain in Hawaii since 1958. The measurements at this location, remote from local sources of pollution, have clearly shown that atmospheric concentrations of CO2 are increasing. The mean concentration of approximately 316 parts per million by volume (ppmv) in 1958 rose to approximately 369 ppmv in 1998. The annual variation is due to CO2 uptake by growing plants. The uptake is highest in the northern hemisphere springtime.

The Olduvai Theory describes the ratio of world energy production and world population. It shows that the Life Expectancy of Industrial Civilization is less than or equal to 100 years: 1930 - 2030.

World oil production in billions of barrels per year (Gb/year) was shown to be reaching a peak before the end of this decade and declining quickly thereafter.

World oil production per capita, that is the ratio of world oil prodution and world population in barrels per capita per year (b/c/year) follows very much the same curve of decline within the next 30 to 50 years.

World energy production per capita, that is in barrels of oil equivalent per capita per year (boe/c/year) also follows the same curve of decline unless an alternative energy production is used to replace oil and gas.

Per capita, the US will still be by far the largest polluter on the planet. In year 2005, the US will be emitting 8.130 trillion kilogram of CO2 per year. Worldwide the total emissions will be 30.0 trillion kilograms of CO2. That is the US will be emitting 8.130 / 30.0 x 100% = 27.1 % of the total CO2 emissions. Now that the US is manufacturing cars in China we will see a larger increase of pollution due to the US technology being sold abroad.

Over its long past history trade has never evolved to require from the trading partners to become legally and morally responsible and accountable for their products from beginning to end. At the end the product becomes a waste and it needs to be properly dispose of. Now trade must be given a new impetus to be in line with the global concepts of the Global Community. You manufacture, produce, mine, farm or create a product, you become legally and morally responsible and accountable of your product from beginning to end (to the point where it actually becomes a waste; you are also responsible for the proper disposable of the waste). This product may be anything and everything from oil & gas, weapons, war products, to genetically engineered food products. All consumer products. All medicinal products! All pharmaceutical products!

These are different ways to express the heat released to the atmosphere by the combustion of gasoline alone. Thus the heating of our atmosphere is not a fake of our imagination. Other calculations such as the greenhouse effect due to CO2 acting as a greenhouse gas keeping the infrared radiation from escaping into space can be found on the website of the Global Community.

Now there are many other ways we have discovered to choke the air we breathe. Automobile exhausts, coal-burning power plant, factory smokestacks, and other waste vents of the industrial age now pump seven billion metric tons of CO2 greenhouse gases into the Earth’s atmosphere each year from fossil fuel combustion. Combustion of fossil fuels destroys the O2 of our air. For each 100 atoms of fossil-fuel carbon burned, about 140 molecules of O2 are consumed. Other factors put our Oxygen supply at risk.

Losses of biomass through deforestation and the cutting down of tropical forests put our supply of oxygen (O2 ) gas at risk. The Earth's forests did not use to play a dominant role in maintaining O2 reserves because they consume just as much of this gas as they produce. Today forests are being destroy at an astronomical rate. No O2 is created after a forest is put down, and more CO2 is produced in the process. In the tropics, ants, termites, bacteria, and fungi eat nearly the entire photosynthetic O2 product. Only a tiny fraction of the organic matter they produce accumulates in swamps and soils or is carried down the rivers for burial on the sea floor. The O2 content of our atmosphere is slowly declining. The content of the atmosphere decreased at an average annual rate of 2 parts per million. The atmosphere contains 210,000 parts per million.

In the Earth's Atmosphere, the volume % of O2 in dry air is 20.98, in order words the abundance percent by volume is 20.98%, or again the abundance parts per million by volume is 209,800. The weight % of O2 at surface level is 23.139%. We are concerned here with the troposphere. We can calculate the volume of the troposphere. The equatorial diameter of the Earth is 12,756.3 km, the radius is therefore 6378.15 km. The troposphere is the atmospheric layer closest to the planet and contains the largest percentage of the mass of the total atmosphere. It is characterized by the density of its air and an average temperature decrease with height. The troposphere starts at the Earth's surface extending at most 16 km high. The troposphere is this part of the atmosphere that is the most dense and which contains approximately 80% of the total air mass. As you climb higher in this layer, the temperature drops from about 17 to -52 degrees Celsius. The air pressure at the top of the troposphere is only 10% of that at sea level (0.1 atmospheres). The density of air at sea level is about 1.2 kilograms per cubic meter. This density decreases at higher altitudes at approximately the same rate that pressure decreases (but not quite as fast). The total mass of the atmosphere is about 5.1 × 1018 kg, a tiny fraction of the earth's total mass.

A bad situation will occur when several cities close to one another have no forests West of them to photosynthesize the Oxygen people need. The air will not have the time to replenish itself quickly enough and air mixing will not be happening fast enough. People gradually become ill and die of a lack of Oxygen.

Despite its small concentration, CO2 is a very important component of Earth's atmosphere, because it traps infrared radiation and enhances the greenhouse effect of water vapor, thus keeping the Earth from cooling down. The initial carbon dioxide in the atmosphere of the young Earth was produced by volcanic activity; this was necessary for a warm and stable climate conducive to life. Volcanic activity now releases about 145-255 million tons of carbon dioxide each year

Answer 3

crude oil does not replenish itself at all. It is fossil fuel, which means it is th result of plant material fosslizing under ground over thousand and thousands of years. We are using it much faster than it can ever be replenished.

If you want to know the truth, the oil, and fuel we burn in our cars that comes from the mid east is the fossilized remains of the garden of Eden. They have found fossilized remains of hippos and other lush river animals from that area, the crude oil is the fossilized forest. So next time you fill up your car, just think, you are burning Eden.
