1. Environmental science is a discipline that focuses exclusively on the study of non-living elements
in the environment.
2. The three ethical perspectives of environmental science are anthropocentrism, geocentrism, and
ecocentrism.
3. Ecocentrism places humans as the central focus and considers human needs and interests as the
primary ethical concern in environmental decision-making.
4. Haribon Foundation is a global environmental organization working towards the conservation of
marine ecosystems.
5. ABS-CBN Bantay Kalikasan is primarily focused on advocating for human rights and social justice.
6. Population growth occurs when the number of births and immigration into a population exceeds
the number of deaths and emigration.
7. Availability of food can be a limiting factor for populations, as insufficient food resources can limit
population growth.
8. Water covers about 70% of the Earth's surface.
9. Water plays a vital role in regulating the Earth's climate through processes such as evaporation,
precipitation, and condensation.
10. Water exists in three states: solid (ice), liquid, and gas (water vapor).
11. Saltwater is a type of water that is safe for human consumption without any treatment.
12. Groundwater is a type of water found in lakes, rivers, and other surface water bodies.
13. Precipitation is a process in the hydrologic cycle where condensed water vapor falls from the
atmosphere to the Earth's surface in the form of rain, snow, sleet, or hail.
14. Coagulation is a water treatment process that involves the addition of chemicals to promote the
clumping together of smaller particles into larger floc.
