8. The Climate Crisis – Ground Zero
The what of climate change
• Warming of the overall Earth climate system
• Due to the cumulative effects of natural changes and human activities
• Primarily driven by human activities since the 20th century
How is climate change different from global warming?
• Used interchangeably, but NOT the same thing
• It all starts with human contribution to each concern
• Global warming is a human produced warming that contributes to climate change

9. The Climate Crisis – Evidence and Consequences

10. The Climate Crisis – Scientific Consensus and Solutions
• Climate scientists agree that climate-warming trends over the past century are extremely
likely due to human activities
• Responding to climate change involves a two-pronged approach: Mitigation and
Adaptation
• The Intergovernmental Panel on Climate Change and its Sixth Assessment Report

11. The Climate Crisis – A Gen Z Perspective
Extinction Rebellion
• Global environmental movement
• Established in the United Kingdom
• Nonviolent civil disobedience to compel
government action
Youth Climate Activists
• Greta Thunberg and Fridays For Future (FFF)
• Disha Ravi – Co-founded the Indian Chapter of
Fridays For Future
• UNICEF noted climate activists

12. The Economics of Climate Crisis
• Climate change – an example of market
failure
• Greenhouse gas externality
• Market fails by over-producing greenhouse
gases
• Increase the price of activities that emit
greenhouse gases
• Low carbon technologies
• Carbon credits – A tool to balance emissions
also allowing companies with less emissions
trade their carbon credits supporting the cause
in the economy as a whole
• The inconvenience of insufficient or
inefficient alternatives

13. Development at the Cost of Environment
• Heathrow Airport – the busiest Airport in
London
• Plans for a third runway and additional
terminal
• Opposition on grounds of greenhouse gas
emissions
• Public opposition to the expansion from
political leaders to environmental campaign
groups and charities
• Initial ruling declaring the expansion unlawful
• Heathrow’s appeal and subsequent lift of the
ban

17. Reasons for Depletion?
• Population Growth
• Technological and Industrial Development
• High Utilization of resources:.

18. Effect of Resource Depletion on Human
Increase the risk of cancer, heart disease, asthma, and many other illnesses
Poverty
Atmospheric Changes
Loss of Biodiversity

19. Impact of Depletion of Resources
• Imbalance in nature:
• Shortage of material:
• Struggle for existence:
• Slackening of economic growth:

20. Possible Solutions to the Problem of Global Energy Crisis
1. Move Towards Renewable Resources
2. Buy Energy-Efficient Products
3. Easier Grid Access
4. Energy Simulation
5. Perform Energy Audit

22. Overview Of Our Plight
● Water covers 70% of our planet
● Only 3% of the world’s water is
freshwater.
● two-third of this fresh water is tucked
away in glaciers or is unavailable for
use.
● Rivers, lakes and aquifers are drying up
or becoming too polluted to use.
● Around 1.1 billion people worldwide
lack access to water.

23. Ways We Waste Water Subconsciously
● Down the drain.
● Long showers
● Leaky faucets and toilets
● Wasting water in the kitchen

24. Organizations Dealing With Water Conservation Issues
● The Stockholm International Water Institute.
● The International Water Management Institute,
Sri Lanka
● Charity: water
● The Art Of Living(India)

26. What Brought Human Life To A Threat…
• Background…
• Studies Done To Bring Good Towards The Society.
• Bring use of alternatives such as Starch-based Polymers, PLA, PHA, PCL Polyesters.
• Switching to Hemp , Shrimp Shells , Cassava , Corn , etc.
• Solutions To Overcome This Issue…

27. Background Of Plastic Plight…
• Below is a peek into the history of when did plastics pollution start and became a
dominant age-old battle for humans, which is still yet to win.
Year 1946: First time when the commercial production plastics increased by three-
fold.
Year 1979: Introduction of Plastic bags for grocery in the U.S.
The 1990s:This was the time when plastic microbeads got its place in the cosmetics
industry and were widely in demand.
Year 1997: This was again the first time when Charles Moore spotted a floating
garbage while sailing, and the Great Pacific Garbage Patch of the Pacific ocean, was
discovered.

30. PLANET OR PLASTIC..?
Wean yourself off disposable plastics.
Stop buying water.
Boycott microbeads.
Cook more.
Purchase items second-hand.
Recycle
Support a bag tax or ban.
Buy in bulk.
Bring your own garment bag to the dry cleaner.
Put pressure on manufacturers

32. What is Biodiversity?
• It is a measure of the variety of organisms present in different ecosystems
• The number and variety of plants, animals and other organisms that exist in an ecosystem
is known as biodiversity
• The richness of biodiversity depends on the climatic conditions and area of the region
• Biodiversity is the result of 3.5 billion years of evolution

33. Types of Biodiversity
• There are three types of Biodiversity
oGENETIC diversity: genetic variability or diversity within a species
oSPECIES diversity: diversity between different species
oECOSYSTEM diversity: diversity between different region

34. Distribution of Biodiversity
• Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as
within regions
• Among other factors, the diversity of all living things (biota) depends on temperature,
precipitation, altitude, soils, geography and the presence of other species.
• Diversity consistently measures higher in the tropics and lower in polar regions generally
• Rain forests that have had wet climates for a long time, have particularly high
biodiversity
• Terrestrial biodiversity is thought to be up to 25 times greater than ocean biodiversity

35. Loss of Biodiversity
• The main cause of the loss of biodiversity can be attributed to the influence of human
beings on the world's ecosystem
• Escalating human population is a major cause of biodiversity loss
• Most of the biodiversity loss has happened post Industrial Revolution through human
activities
• Habitat loss and degradation
• Habitat loss and degradation create the biggest single source of pressure on biodiversity
worldwide
• For terrestrial ecosystems, habitat loss is largely accounted for by conversion of wild
lands to agriculture, which now accounts for some 30% of land globally
• In some areas, it has recently been partly driven by the demand for biofuels

36. Importance of Biodiversity
At least 40 per cent of the world’s economy and 80 per cent of the needs of the poor are
derived from biological resources. In addition, the richer the diversity of life, the greater
the opportunity for medical discoveries, economic development, and adaptive responses
to such new challenges as climate change.

37. Zones in a Biosphere reserve
A biosphere reserve is divided into three zones: Core, buffer and
manipulation.
• Core Zone: In core or natural zone human activity is not allowed.
This area is legally protected and undisturbed ecosystem.
• Buffer zone: The immediate surrounding area of core zone is
buffer zone. Here limited human activities live like research,
education and research strategy is permitted.
• Manipulation zone: Manipulation or transition zone is the
outermost or peripheral area of biosphere reserve. With the
cooperation of reserve management and local people several
human activities like settlements, cropping, recreation, and
forestry are carried out without disturbing the environment. Buffer
zone has different parts like forestry, agriculture, tourism and
restoration regions.
