PPT Lecture: Vanishing

Species

Slide 2 - BiodiversityBio = Life

Diversity = Different# of different species in an area.

Slide 3 - Stop and Think!What would have a greater biodiversity?

A tropical rain forest or a desert?Pretend both are equal in size.

Slide 4 - Stop and Think Again!What country has the greatest biodiversity of mammals?

Canada = 163

United States = 367

Mexico = 439

Slide 5 - Terrestrial BiodiversityTends to increase the closer an areas is to the equator because

it is warmer.Tropical regions contains 2/3 of all land species on Earth!

Slide 6 - Stop and Think!What would have a greater Biodiversity? The small island of

Maui or the bigger island of Iceland?

Slide 7 - Importance of BiodiversityNature – Life depends on lIfe!

Humans – Medicine, Oxygen, Food!

Slide 8 - Loss of BiodiversityExtinction – Disappearance of a species!

Endangered Species – When a species is close to extinction!

Threatened Species – When pop. of species declines rapidly

Slide 9 - Threats to Biodiversity

Habitat Loss

Habitat Fragmentation

Habitat Degradation

Slide 10 - Habitat LossHabitat = Address

Destroying habitats for buildings (businesses and housing)

Slide 11 - Habitat Fragmentation

Fragment = Broken PieceTo break up or separate a habitat!

Slide 12 - Habitat DegradationDegrade – Worsen

To make a habitat worse by pollution!

Slide 13 - Purpose of LectureConservation!

Conserve – preserve or maintain the quantity and quality of habitats!
