Study Notes

Biodiversity

Biodiversity refers to the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems.
The United Nations Convention on Biological Diversity defines biodiversity as the variability among living organisms from all sources.
An ecosystem is the unit of interaction between the biotic community and its physical environment in a given area.

Habitat and Ecosystem

A habitat is a place in which a particular species of organism lives.
An ecosystem is a self-contained community of microorganisms, animals, and plants that interact with each other and with their physical environment.

Importance of Biodiversity

Biodiversity supports healthy ecosystems.
It is an essential part of the solution to climate change.
It is good for the economy.
It is an integral part of culture and identity.
It provides raw materials like lumber, food, spices, etc.
It provides opportunities for recreational activities, such as bird watching, scuba diving, snorkeling, and nature photography.
It serves as the source of medicine.

Products of Biodiversity

Oxygen
Food
Medicine

Harmful Effects of Global Climate Change

Reduces biodiversity
Increases the risk of diseases
Causes alterations within species groups or within the environment

Government Roles in Reducing the Threat of Climate Change

Regulate carbon dioxide and methane as pollutants
Implement carbon taxes
Cap total CO2 emissions
Subsidize energy-efficient technologies
Improve energy efficiency to reduce fossil fuel use
Shift from coal to natural gas
Shift to renewable energy sources

Philippine Biodiversity

The Philippines is one of the 154 member countries that signed the United Nations Convention on Biological Diversity.
72% of wildlife in the country are already threatened with extinction.
Several species of plants, frogs, reptiles, and insects remain to be documented.

Threats to Biodiversity

Environmental pollution
Domestic agriculture and industrial wastes are poorly treated and discharged into the sea and other bodies of water.
Pollution can lead to diseases and pollution stresses, such as coral bleaching on reefs.

Underlying Causes of the Loss of Biodiversity

Population growth and increasing resource consumption
Ignorance about species and ecosystems
Poorly conceived policies and poor law enforcement
Effects of global trading systems
Inequity of resource distribution
Apathy or failure to account for the value of biodiversity
