What is the value of biodiversity in current era?
The role of biodiversity in providing ecosystem services is twofold. Firstly, biodiversity is directly used as a source for food, fibre, fuel and other extractable resources. Secondly, biodiversity plays an important role in ecosystem processes providing the regulating, cultural and supporting services.
Biological diversity, abbreviated as biodiversity, represent the sum total of various life forms such as unicellular fungi, protozoa, bacteria, and multi cellular organisms such as plants, fishes, and mammals at various biological levels including gens, habitats, and ecosystem .
What can we do to maintain or improve the status of the Philippine biodiversity?
- Conserve biodiversity in forest areas.
- Reduce forest degradation in targeted priority watersheds.
- Build capacity to conserve biodiversity, manage forests, and support low emissions development.

How is biodiversity distributed across the earth?
Biodiversity is unevenly distributed across the planet. A range of factors contribute to this distribution, including the global climatic gradient, the current and historical distribution of land masses, and geographical barriers, such as mountains.
