One risk for accessing carbon from the ground is that it may cause soil contamination. Soil when exposed to large amount of gases and other organically decaying materials can absorb these into their make-up. Fossil fuels are extracted from the ground through drilling processes. When the drilling is unsuccessful, pockets created within the soil can create areas for contamination. When soil is contaminated by fossil fuels, it can no longer be use for agricultural purposes.
I’ll like to answer but Where the question ?
Answer:
It's large compared to other countries, but only because of consumerism
Explanation:
The United States is the 5th largest ecological footprint in the world, with about half the population contributing to that factor, however this is only because the United States runs specifically on capitalism and consumerism, so every citizen contributes one way or another. America uses high energy and fossil fuel consumption with high functioning biological resources in carbon cycling. So although comparing California to France (because California has a larger footprint.), it's not a fair comparision due to technology
If we take the wolf as a species, then we can easily find its place and evolutionary path through this cladogram of chordates. The wolf is a vertebrate, so we start from vertebrae. It is an animal that has jaws and paired appendages. Continuing further up the cladogram we reach the development of lungs, and the wolfs have lungs for breathing. Then we come to the development of four limbs, and the wolfs have four limbs. Next comes the endothermy, meaning that the animal is able to regulate its own body temperature, thus it is warmblooded, and the wolfs are warmblooded animals. As last we come to the mammals, and the wolfs are part of the mammals, so we can classify them in that branch of the chordate cladogram.
