Which of the following is not an environmental impact of resource extraction? a. loss of soil b. increased resource supply c. water contamination d. loss of vegetation select the best answer from the choices provided

The correct answer is - increased resource supply.

The resource extraction is a process though which the supply of resources on the market is achieved. In the past century, the extraction has been increasing constantly, thus the supply of resources on the market increased significantly because the demand for the same increased significantly.

On the other hand, the extraction of resources, very often, has very bad impact on the environment. The soils are destroyed, which is especially concerning considering the fact that fertile soils are desperately needed. The vegetation is cleared or polluted to a degree where it dies out, and the water also gets contaminated. Lot of this issues are extremely serious, and urgent measures have to be taken in order for such damage to be stopped.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.  

d. changes in climate and historical records
