As a result of tar trade and shipbuilding industry Kokkola was for a time one of the richest towns in Finland.

The tar sands are hundreds of square kilometers of bitumen, a viscous and corrosive tarlike deposit.

Junkies find veins in their toes when the ones in their arms and their legs collapse. Developing tar sands and coal shale is the equivalent. Here are just a few of the investments that I personally think make sense.

If you let that go unregulated, you'll continue to make and break chemical bonds, forming an even more diverse mixture of molecules that then forms this kind of black tarry stuff in your pan, right, that's difficult to wash out. So that's what the origin of life would have looked like.

Besides the largest conventional oil reserves and the second largest natural gas reserves in the Western Hemisphere, Venezuela has non conventional oil deposits (extra heavy crude oil, bitumen and tar sands) approximately equal to the world's reserves of conventional oil.
