- Biological diversity is resource upon which families, communities, nations and future generations depend
- link between all organisms on earth, binding each into an interdependent ecosystem, all species have their role
- It is the web of life.
- if there is a biodiversity crisis, our health and livelihoods are at risk too.
- currently using 25% more natural resources than planet can sustain → species, habitats and local communities under pressure or direct threats
- Biodiversity underpins the health of the planet and has a direct impact on all our lives.
- reduced biodiversity → millions of people face a future where food supplies more vulnerable to pests and disease, fresh water irregular/short supply
- Ecosystem services = all services we get from natural world we often take for granted (eg. H2O, soil formation/protection, pollution breakdown/absorption, climate stability and recovery from natural disasters)
- According to IUCN, the World Conservation Union, monetary value of goods/services provided by ecosystems estimated to amount to US$33 trillion / yr
- We harvest estimated 50,000-70,000 plant species for medicine worldwide.
- 100 million+ metric tonnes of aquatic life (fish, molluscs, crustaceans) taken from the wild every year
- wild animal meat form critical contribution to food sources + livelihoods in many
Biodiversity is the variety of different types of life found on earth. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet.

Definition of Biodiversity
Biological diversity, or biodiversity for short, is
Ecosystem: A biological community of interacting organisms and their physical environment.
What is Biodiversity: The variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable.
Q: Why is it important to preserve ecosystems
A: Conserving ecosystems guarantees the very existence of every animal and plant species on Earth. The natural world consists of various complex interactions between different ecosystems. Organisms influence one another and exist in an ecosystem created by nature’s balance.
