BIodiversidad

2.  Biodiversity is the variability among living organisms
from all sources, including terrestrial, marine, and
other aquatic ecosystems and the ecological complexes
of which they are part; this includes diversity within
species, between species, and of ecosystems.

3.  The concept was coined in 1985 in the National Forum
on Biological Diversity of the United States by Edward
O. Wilson

4. Why is biodiversity loss a concern?
 Biodiversity is essential for ecosystem services and
hence for human well-being.
 Biodiversity is essential for provisioning material
welfare and livelihoods to include security, resiliency,
social relations, health.
 For example, some people have benefited over the last
century from the conversion of natural ecosystems to
human-dominated ecosystems and from the
exploitation of biodiversity

6.  Biodiversity includes all modified and unmodified
ecosystems

8. What are the causes of biodiversity loss?
 Habitat transformation, particularly from conversion to
agriculture.
 Overexploitation (especially overfishing and deforestatiom).
 Biotic exchange. The spread of invasive alien species and disease
organisms has increased because of increased trade and travel.
 Nutrient loading. For example, synthetic production of nitrogen
fertilizer .
 Anthropogenic climate change. Global Warming.

9. Biodiversity in Mexico
 Mexico is considered a megadiverse country
 Mexico is considered a "megadiverse" country, because
it belongs to the select group of nations possessing
the greatest number and variety of animals and plants,
almost 70% of global species diversity.
