3. Introduction of Biodiversity
•Biodiversity refers to diversity of living
organisms.it reflects the number, variety
and variability of living creatures
includes different species of
microorganisms, fungi, plants and
animals and the ecosystem they live in
•the term biodiversity was first coined
by Walter G. Rosen

5. Biodiversity loss
•biodiversity loss is the decline in the
variety and number of species in an
ecosystem over time
•it has become a significant environmental
issue as numerous species are becoming
endangered or extinct due to human
activities such as over exploitation, habitat
destruction and human-induced climate
change

6. Causes of Biodiversity Loss
Natural causes
1)Natural Diasasters
2) Disease
3) Competition and predation
Anthropogenic causes
1) Habitat destruction and fragmentation
2) Over-exploitation of biological resources
3) Alien species invasion
Other factors
1)Pollution
2) Climate change

7. •Amino acids are joined with peptide bond
to form proteins.
•Peptidyl transferase enzyme catalyses
the synthesis of peptide bond.
• Property of protein depends (i) on
sequence of amino acid and (ii)
configuration of protein molecules.

8. Impacts of Biodiversity loss
Biodiversity loss is a serious issue with
numerous and far reaching impacts on both
human well-being and the health of
ecosystems
Ecological impact
1)Loss of ecosystem services
2)Accelerated rate of species extinction
3) Disruption of food webs
4) Increase in zoonotic diseases
Economic impact
1)Loss on food security
2) Increased Expenditure on disaster

9. Social and cultural impacts
1)Loss of cultural and spiritual values
2) Increased environmental refugees
3) Reduced access to ecosystem services

10. Current Scenario of Biodiversity
Loss
As per living Planet Report
It is a biennial report published by the
World Wildlife fund(WWF)
•Average decline in Species
population: there has been average
decline of 69% in monitored wildlife
population around the world between
1970 and 2018
•Trend by Region: Latin America has
shown the greatest regional decline in
average population abundance (94%)

11. •Trend by biome: the most significant
declines in population have occurred in
freshwater ecosystems, where
populations have declined by an average
of 83% since 1970
