Why is the endangered species act often a center of controversy? scientists want to make all species endangered. animals are listed that are not worth saving. endangered species cannot be moved to similar habitats not threatened by construction. it has not been successful. landowners are concerned that federal officials will restrict the use of private land if threatened or endangered species are found on it?

Answers;

Landowners are concerned that federal officials will restrict the use of private land if threatened or endangered species are found on it.

Explanation;

-The Endangered Species Act main legislation for protecting biodiversity in the United States.

-The Act has often generated controversy because its enforcement requires changes in our land use.

-Critics of the act cite a variety of current controversies, from spotted owls and salmon in the Pacific Northwest to red-cockaded,woodpeckers and sea turtles in the Southeast.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

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.
