Study Notes
Ecological Diversity
- Ecological diversity refers to the number of species in a community
- It also includes variations of climatic and altitudinal conditions, ecological habitats, and biodiversity
Biodiversity and Society
- Biodiversity drives the global economy and supplies almost all of society's needs
- Historical uses of energy sources:
- 1000 BC: Coal used for heating and cooking in northeastern China
- 400 BC: Water energy used for powering machineries and irrigation by the Ancient Greeks and Romans
- 347 AD: China uses oil wells with extensive bamboo pipelines for lighting and heating
- 1000: Persia uses first windmills to pump water and grind grain
- 1300: Windmills begin to form modern pinwheel shape in Western Europe
- 1590s: The Dutch develop the most efficient version of the windmill for navigation
- 1600s: Coal and the British discover that cooking coal transforms it into hot-burning coal
- 1700s: Coal replaces other energy sources and becomes the primary source of energy around the world
- 1820s: Natural gas used as a source of light
- 1830s: Electric generator, motor, and relay developed based on Michael Faraday's discovery of electromagnetism
- 1850s: Commercial oil drilling and distillation of kerosene from petroleum
- 1860s: Augustine Mouchot develops the first solar-powered system for industrial machinery
- 1892: First utilization of geothermal heat to power
- 1942: First nuclear fission reactor designed and built
Health and Medicine
- Biodiversity underpins nature's contributions to people and provides ecosystem goods and services essential to human health and well-being
- Biodiversity is integral to key development sectors that modulate health outcomes directly or indirectly, such as pharmacy, biochemistry, agriculture, or tourism
Food and Nutrition
- Biodiversity contributes directly to food security, nutrition, and well-being by providing a variety of plant and animal sources from domesticated and wild sources
- Habitat loss, fragmentation, edge effect, noise and light pollution, invasive species, carbon storage, and sequestration threaten biodiversity
Water Resources
- Earliest recorded civilization situated near bodies of rivers or lakes, which marks the earliest record of water consumption
- Well drilling began 7000 years ago in the Middle East (Israel) for potable and drinkable water
- Rivers and lakes are used for irrigation of crops
- Floodways are used to prevent flooding of nearby communities and damage of crops
- Aqueducts were invented and built by later civilizations, such as the Romans and Greeks, to deliver reliable water supply
- Mixed forests and biodiversity play a crucial role in water resources, providing natural filtration and storage systems
Environmental Laws and Jurisprudence in the Philippines
- P.D.#1152 – Philippine Environmental Code
- Chapter 1 – Fisheries and Aquatic Resources: aims to protect and conserve the country's fisheries and aquatic resources
- Chapter 2 – Wildlife: focuses on the protection and conservation of wildlife in the Philippines, regulating trade and transport of wildlife and their by-products, and establishing and managing wildlife sanctuaries and protected areas
