Transcript of Biodiversity

Why is Biodiversity Important? Economics of Ecosystems What to Do Next? Credits A Balanced Ecosystem Though it may be true that there is a "survival of the fittest" among any given species, every species depends on the services provided by other species to ensure survival. What Does a Healthy Biodiversity Mean for Us? Biodiversity boosts the ecosystem productivity. That is quite a lot of services we get for free and the cost of replacing these services would be extremely expensive, if at all possible. No one group, organization, company or government alone can do the job of protecting this planets biodiversity. created & presented by:

Full Circle by Loreena McKennitt
"Our planet supports a wide variety of plants, animals and microorganisms. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. Healthy ecosystems can better withstand and recover from a variety of disasters. Biodiversity What is it? it's a global issue... The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth."
---Why Is Biodiversity Important? Who Cares? GlobalIssues.org We may dominate this planet, but if we don't preserve it's diverse wildlife, we will loose the very things that we need to survive. Biological Resources:
Food
Medical resources
Wood products
Ornamental plants
Breeding stocks
Future resources
Diversity in genes, species and ecoosystems Ecosystem Services:
Protection of water resources
Soils formation and protection
Nutrient storage and recycling
Pollution breakdown and absorption
Contribution to climate stability
Maintenance of ecosystems
Recovery from unpredictable events Social Benefits:
Research, education and monitoring
Recreation and tourism
Cultural values Between plants and animals

By symbiosis "At least 40% of the world's economy and 80% of the needs of the poor are derived from biological resources."

"Planting and protecting nearly 12,000 hectares of mangroves in Vietnam costs just over a million dollars but saved annual expenditures on dyke maintenance of well over seven million dollars."
