Science & Technology: Environmental Sustainability and Scientific Disciplines

Nephology is the branch of meteorology that deals with clouds - their formation, classification, and physical properties. The prefix 'nepho-' comes from the Greek word for cloud. This is distinct from neurology (study of the brain and nervous system) or cetology (study of whales).

Petrology is the branch of geology that studies the origin, composition, structure, and properties of rocks. The prefix 'petro-' comes from the Greek word for rock or stone. This is distinct from pedology (study of soils), zoology (study of animals), or ethology (animal behavior).

Biology comes from the Greek words 'bios' (life) and 'logos' (study of), literally meaning the study of life. It encompasses all living organisms including plants, animals, and microorganisms. While biology includes animal behavior, that's a specific subfield called ethology, not the entire discipline.

Psychology is the scientific study of the mind and behavior, encompassing conscious and unconscious phenomena, feelings, and thoughts. The word comes from Greek: 'psyche' (mind/soul) and 'logos' (study of). Physiology is the study of how organisms function normally, phytology (botany) studies plants, and pedology studies soils.

Conchology is the scientific study of shells, particularly mollusk shells. It's a branch of malacology (study of mollusks) that focuses specifically on shell structure, classification, and diversity.

Pomology is the branch of botany that studies fruits and fruit cultivation. It covers fruit production, breeding, development, and post-harvest handling. Mycology studies fungi, while pathology studies diseases.

Cartology (or cartography) is the science of making maps and map-making techniques. It involves projection systems, scale, representation, and map design. The name derives from 'carta' (map/chart).

Anthropology is the comprehensive study of humans, human societies, and cultures. It encompasses biological anthropology (human evolution), cultural anthropology (societies), archaeology, and linguistic anthropology. Not to be confused with entomology (insects).

Pyrology is the study of fire and combustion processes. The prefix 'pyro-' comes from Greek for fire (as in pyrotechnics). Hydrology studies water, somatology studies body constitution, and apiology studies bees.

Hippology is the scientific study of horses, including their anatomy, physiology, breeding, training, and care. The name derives from 'hippos' (Greek for horse), not to be confused with hippopotamus (which is studied in zoology).

A rainbow displays the spectrum: red, orange, yellow, green, blue, indigo, and violet (ROYGBIV). Pink is not part of the natural rainbow spectrum - it's a non-spectral color not produced by prism dispersion of white light.

Earth revolves around the Sun in an elliptical orbit, taking approximately 365.25 days to complete one revolution. This heliocentric model is fundamental to astronomy - the other planets listed (Mars, Venus) also revolve around the Sun, not each other.

Myrmecology is the specialized branch of entomology dedicated to the study of ants. It covers ant behavior, ecology, social organization, and classification. Archaeology studies human history through excavation, anthropology studies humans, and otology studies ears.

The lifecycle carbon footprint of a mobile phone, including manufacturing, usage, and disposal, averages around 5.5kg CO2 annually. This accounts for both production emissions and operational energy use over the phone's lifespan. Options A, C, and D represent orders of magnitude that don't align with typical mobile device emissions data.

Nuru Design, a social enterprise providing affordable lighting solutions in Africa, co-won the 2009-10 UNEP Sasakawa Prize with TWP for their innovative sustainable energy projects. The prize recognizes grassroots environmental achievements. Other options are notable environmentalists but not the specific 2009-10 awardee.

The 2010 FIFA World Cup in South Africa generated approximately 2.7 million tons of CO2, primarily from international travel, stadium construction, and energy use during the tournament. This figure was calculated by EU Infrastructure studies on major sporting event emissions. Other events listed had different carbon footprints.

Even with a 50% reduction in greenhouse gas emissions, global temperatures are still projected to rise by approximately 2°C by 2050 due to the cumulative effect of greenhouse gases already in the atmosphere. This is based on climate modeling studies. The warming wouldn't stop or reverse immediately due to climate inertia.

Gro Harlem Brundtland, former Prime Minister of Norway, led the World Commission on Environment and Development (1983-1987), which produced the influential Brundtland Report defining sustainable development. Her leadership was instrumental in establishing sustainable development as a global policy concept. Other options were also Nordic leaders but not associated with this commission.
