A recent study of ecological footprints concluded that ______. A. Earth's carrying capacity would increase if per capita meat co
nsumption increased B. current demand by industrialized countries for resources is much smaller than the ecological footprint of those countries C. it is not possible for technological improvements to increase Earth's carrying capacity for humans D. the ecological footprint of the United States is large because per capita resource use is high
The correct option is (D) The ecological footprint of the United States is large because per capita resource use is high.
<h3>What is ecological footprint?</h3>
The Global Footprint Network advocates using the ecological footprint to determine how much nature is required to support a certain population or economy.
The ecological footprint accounting system tracks how much nature is being used and produced.The Ecological Footprint calculates the total productive areas for which a population, a person, or a product competes on the demand side.
It evaluates the ecological resources required by a specific population or product in order to produce the natural resources it consumes, as well as to absorb its waste, particularly carbon emissions.
The biocapacity of a city, state, or country, on the supply side, measures how productive its ecological resources are (including cropland, grazing land, forest land, fishing grounds, and built-up land).
These regions can also be used to absorb the garbage we produce, particularly our carbon emissions from burning fossil fuels, especially if they are left unharvested.

The number of electrons and protons is eleven in sodium. After sodium (Na) has transferred its electron to the chlorine atom (Cl) it becomes a positively charged ion. This is because as electrons are negatively charged, losing of an electron will increase the number of protons (i.e 11) as compared to the number of electrons (i.e 10) in sodium (Na) atom. Hence, a positive charge will be acquired by the sodium (Na) ions.
<span>One test might be the acid content of the water. Water that does not have a neutral pH might be less conducive to life. Another water quality test might be oxygen levels in the water. Inadequate oxygen levels may also reduce the amount of aquatic life. The presence of pollutants might be a third test. Chemicals that poison the water would negatively impact the number and variety of organisms present.</span>
