Tar sands have affected over 75% of the habitat in the Alberta taiga forest due to the clearing of the forests and the oil ponds that come from the extraction. These tar sands also create awful toxic oil ponds that affect wildlife and surrounding vegetation. Oil extraction also affects the forest soil, which harms tree and plant growth.
The name tar sands was applied to bituminous sands in the late 19th and early 20th century. [18] People who saw the bituminous sands during this period were familiar with the large amounts of tar residue produced in urban areas as a by-product of the manufacture of coal gas for urban heating and lighting.

The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, a heavy and viscous form of petroleum, in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market.
Tar sands get a lot of bad press, much of it to do with the fact that the extraction and processing of tar sands bitumen creates a lot more pollution than other fuel sources. A few companies are ...
The largest single plant in Canada to use in situ production is Imperial Oil's Cold Lake oil sand plant. This plant uses a technique called cyclic steam injection . Using this method, the company pumps high-pressure steam into a section of the underground reservoir for a week or so, then pumps the liquid oil out for as long as several months.
In the La Brea Tar Pits, more than one million bones have been recovered since 1906. 231 vertebrate species, 234 invertebrate species, and 159 plant species have been identified. [9] The most frequent large mammal found in the La Brea Tar Pits is the dire wolf , one of the most famous prehistoric carnivores that lived during the Pleistocene ...
Most people plan to either be buried or cremated when they die, but there is another, environmentally friendly option: Human composting. "So instead of being cremated and turned into ash, you're ...
Habitat degradation is caused by the depletion of resources, in which human activities are the primary driving force. [50] [51] One major impact that the depletion of fish stocks causes is a dynamic change and erosion to marine food webs, which can ultimately lead to ecosystem collapse because of the imbalance created for other marine species.
