Overall population growth<span> and change is another area of </span>importance for population geographers<span>. This is because the world's </span>population<span> has grown dramatically over the last two centuries. To </span>study<span> this overall subject, </span>population growth<span> is looked at via natural increase.</span>
An ecological deficit occurs when the Footprint of a population exceeds the biocapacity of the area available to that population. Conversely, an ecological reserve exists when the biocapacity of a region exceeds its population's Footprint. ... The Ecological Footprint is usually measured in global hectares.
Ecological reserves are areas selected to preserve representative and special natural ecosystems, plant and animal species, features and phenomena. Scientific research and educational purposes are the principal uses of ecological reserves.
Answer:
IR refers to Infrared Radiation
Explanation:
In Environmental Science Radiation is very important because many natural processes rely on the interaction with the radiation from the sun. Radiation is classified by wavelengths visible spectrum is at about 380 to 740 nanometers, Infrared radiation wavelength is at 700 to 1050 nanometers.
Environmental Science use IR a lot in the studies because organisms heat is emitted in this radiation, because of there are many applications to the IR, Such as Climatology when studying the solar radiation absorption and reflection, Geography when analyzing satellite imagery or Biology for having a better understanding of organisms with the capabilities to capture Infrared radiation or to measure the density of a forest.
Answer:
1) World food supplies have decreased.
