What are the Tar Pits? The Tar Pits have fascinated scientists and visitors for over a century, and today, this area is the only actively excavated Ice Age fossil site found in an urban location in the world!
What are tar sands and why are they a problem?
Tar sands extraction emits up to three times more global warming pollution than does producing the same quantity of conventional crude. It also depletes and pollutes freshwater resources and creates giant ponds of toxic waste. Refining the sticky black substance produces piles of petroleum coke, a hazardous by-product.
Why are the tar sands bad?
In fact, oil from tar sands is one of the most destructive, carbon-intensive and toxic fuels on the planet. Producing it releases three times as much greenhouse gas pollution as conventional crude oil does. In fact, it has become one of the fastest-growing sources of greenhouse gas emissions in that country.
What is tar sand used for?
Tar sands (also known as oil sands) are a mixture of mostly sand, clay, water, and a thick, molasses-like substance called bitumen. Bitumen is made of hydrocarbons—the same molecules in liquid oil—and is used to produce gasoline and other petroleum products.
Can you escape a tar pit?
The tar pits were the bane of prehistoric man and animals. You see they are like quicksand only deadlier. E-mail, cell phones and PDA’s will all lead you into today’s modern tar pits and suck you under if you allow them to. They can’t be escaped and they will bury you if you allow it.
Can you swim in tar?
The Tar River Reservoir is sampled at the reservoir boat ramp off of Bend of the River Road. This is the only public access to the reservoir and is a very popular put-in for boaters and paddlers looking to fish and swim.
What is the dirtiest oil on Earth?
Tar sands
Tar sands are the dirtiest source of oil on Earth. This extreme source of oil is currently being mined mainly in Alberta Canada, however, oil companies are now pursuing tar sands mines in the U.S. West. Tar sands are composed of clay, sand, water, and bitumen (a heavy black hydrocarbon).
What are the pros and cons of tar sands?
- Very large supply. Second largest oil field in the world.
- Economically recoverable at today’s oil prices.
- Will help keep oil prices relatively low.
- Enormous growth potential.
- Big economic driver in Alberta.
- Stable source country (a rarity for oil)
- GHG emissions could potentially be minimized through CCS.
How toxic are tar sands?
Studies have found levels of mercury, arsenic, lead, and other toxins at elevated levels near the area’s tar sands excavation sites. 5 These chemicals are known carcinogens and cause the types of rare cancers—including cancer of the bile ducts—that are on the rise among members of the Fort Chipewyan community.
Where is tar found?
It is a natural substance, oozing out of the ground in places like the La Brea tar pits. Usually it is made by heating coal inside a chemical apparatus. Most tar is produced from coal as a byproduct of coke production, but it can also be produced from petroleum, peat or wood.
Are tar sands renewable?
Fossil fuels are the most commonly used types of non-renewable energy. Two other less-used sources of fossil fuels are oil shales and tar sands.
How deep do tar pits go?
3. The tar pits are only a few inches deep! Did you always imagine prehistoric animals sinking into the tar pit goo like it was a sticky quicksand, until they finally sank out of sight?
