Measured At Different LVLS

GENETICS-VARIATION BETWEEN INDIVIDUALS OF THE SAME SPECIES

SPECIES-VARIETY OF SPECIES CONTAINED IN AN AREA

ECOSYSTEM-PLANTS AND ANIMALS TOGETHER WITH THE PHYSICAL CHARACTERISTICS OF THEIR ENVIRONMENT.

Nineteen Trees Sampled In Panama Were Found To Contain 1,200 Different Beetle Species Alone.

Global species estimates range from 2 million to 100 million species.

Only 1.4 million species have been named

is a vital

aspect of the food-production

Global human population is

expected to

rise to over 9 billion

by 2050

Placing tremendous pressure on

food-production

systems

Paul Ralph Ehrlich Much of this increase in

extinction rate appears to be due to the impact of humans. Habitat Depletion Pollution Introduction of disease Introduction of invasive species Over exploitation

Page 15: Biodeversity powerpoint(u can be winner by this ppt )

25% of the earth’s birds species have been driven to extinction by humans (especially on islands).

Threatened with Extinction

11% of birds

18% of mammals

5% of fish

8% of plants Loss of birds

Tropical Rainforests Facts

Each year approximately 78 million

acres of rainforest are destroyed.

As many as 137 species are going extinct each day.

The substrate (soil) is poor with most of the nutrients existing in

the trees and plants.

Page 20: Biodeversity powerpoint(u can be winner by this ppt )

Poor soil leads to burning the land to increase top-soil nutrients.

Burning trees releases carbon into the atmosphere which exacerbates the greenhouse effect and increases temperature.

HOW TO PRESERVE

In Situ Conservation – from inside the natural habitat

Ex Situ Conservation - out of the natural habitat(Species-based)

STEPS TAKEN

Page 25: Biodeversity powerpoint(u can be winner by this ppt )

CONVENTION ON BIODIVERSITY,SIGNED BY 156 NATIONS AT THE UNITED NATIONS CONFERENCE ON ENVIRONMENT AND DEVELOPMENT ( THE EARTH SUMMIT ) IN RIO IN 1992

AT GLOBAL LEVEL

Page 26: Biodeversity powerpoint(u can be winner by this ppt )

IUCN(THE WORLD CONSERVATION UNION)

IUCN -RESPONSIBLE FOR THE IDEA OF COMPILING LISTS OF THREATENED SPECIES AS A MEANS OF DRAWING ATTENTION TO THE PLIGHT OF SPECIES FACED WITH EXTINCTION. THESE LISTS BECAME KNOWN AS RED DATA BOOKS ( RDBS ).

Steps taken to preserve biodiversity in india

India,in top 12 mega biodiversity countries

The Ministry of Environment and Forests constituted the National Afforestation and Eco-development Board (NAEB) in August 1992.

BEAM OF ACTS AND NATIONAL POLICIES TO PRESERVE BIODIVERSITY

Forest Act, 1927 Wildlife (Protection) Act, 1972 Environment (Protection) Act, 1986 National Agricultural Policy National Land Use Policy National Policy and Action Strategy on

Biodiversity
