C
Given that the World population changed little between this time, we can gather than the birth and death rates were similar, since they seem to cancel each other out from 1200-1400. To clarify, think of this. If you add something to a total (think births to population), but take away the same number (think deaths from population) you end up with the same total as before. Because of this, A is the correct answer choice (The birth rate and death rate were about equal).
I personally believe that the right answer is C. Other overpopulation results in more living organisms, and since the pollution has intoxicated the living, they die releasing the carbon into the soil. So there is high amounts of carbon and less of the organic compounds because the overdose on carbon.
A large portion of our energy originates from consuming fossil fuels , consuming non-renewable energy sources dirties the air by putting all ash of harmful gases in it and also ozone harming substances which influence the atmosphere.
Conserving energy can anticipate things like synthetic compounds going into the air from control plants, or on the off chance that we drive less then we annihilate the air less in light of less CO2 outflows. Conserving energy additionally forestalls things like oil slicks into the sea.
Conserving energy can help with diminishing air, water, and land contamination in light of the diverse options we have for energy. We have sun powered power energy that is a sustainable source. Sun based power vitality doesn't contaminate the air that we inhale or discharge any ozone harming substances while creating power. You likewise have tidal energy that believers waves into clean, contamination free power. This shields the water from being dirtied.
A.economic Geography is the answer
