WHAT IS EARTH DAY AND WHY IS IT OBSERVED AND ITS IMPORTANCE TO MANKIND !!! Role of humans regarding conservation of trees and plants

1. EARTH DAY

2. EARTH DAY
• One of the most widely celebrated
environmental events across the
Globe.
• To increase awareness and
appreciation of the Earth’s natural
Environment.
• Celebrated in more than 192
countries each year.
• Originally celebrated at Spring
Equinox around 21 March
• But now the United Nations has
designated 22 April as the
International Mother Earth Day.

3. THEME OF 2023:Invest in Our
Planet
• The theme of World Earth Day 2023 is "Invest in
Our Planet", calling for businesses to shift
towards sustainable practices. Earth Day is
celebrated on April 22 every year.
GOAL
• planting 7.8 billion trees over next five years
• Fight climate change and pollution
• Reduce CO2 emissions
• Help counteract loss of species
• Help communities and livelihood

4. IMPORTANCE AND VALUE OF
PLANTS/TREES

5. TREES/PLANTS: COMMUNITY AND
SOCIAL VALUE
• Important part of every community.
• Streets, parks, playgrounds – create peaceful,
aesthetic and pleasing environment.
• Increase the quality of life by bringing natural
elements and wildlife habitats.

6. TREES /PLANTS: ECOLOGICAL AND
ENVIRONMENTAL VALUE
• Provide oxygen, improve
air quality
• Conserve water
• Preserve soil
• Support wildlife
• One acre of forest
absorb 6 tonnes of CO2
and gives out 4 tonnes
of O2.
• Trees, shrubs and turf
filter air by removing
dust and absorbing
other pollutants like CO, SO2, NO2

7. TREES /PLANTS: ECOLOGICAL AND
ENVIRONMENTAL VALUE
• Control climate change by
moderating the effects of sun,
rain and wind
• Leaves absorb and filter sun’s
radiation – keep cool in
summer
• Preserve warmth by providing
screen from harsh wind
Shield us from downfall of
rain, sleet and hail
• Lower air temperature and
reduce intensity of
greenhouse effect

8. TREES /PLANTS: ECOLOGICAL AND
ENVIRONMENTAL VALUE
• Holds soil in place and fight
Erosion.
• Absorbs and stores
rainwater.
• Reduce runoff and
sediment deposit after
storms.
• Helps the ground water
supply recharge, prevents
the transport of chemicals
into streams and prevents
flooding.
• Fallen leaves make
excellent compost that
enriches soil.

9. TREES/PLANTS : ASSOCIATION
WITH WILDLIFE
• Herbivores – dependent on
leaves for nourishment.
• Monkeys and other animals –
feed on fruits.
• Birds , bats and insects – feed
on flowers for nectar.
• Help in dispersing seed.
• Home to hundreds of living
Creatures.
• Branch of tree – protection to
birds and squirrels from
Predators.

10. ROLE OF TREES/PLANTS :ASSOCIATION WITH BIO
DIVERSITY
• The diversity of plants on the planet earth is an important resource for food, shelter,
and agriculture.
• There is a great variation in the biodiversity, resulting from human and ecosystem
interaction for certain food and development for the survival of the human population,
regardless of the pests, climate fluctuations, diseases, droughts and other unexpected
environmental events.
• About thousands of plant crop species have been identified, developed, used and
relied on for the purpose of food and agricultural production in human history. These
plants include bushes, grasses, herbs, shrubs, trees, vines, ferns, and mosses.
• As per the requirement on this moderately small number of crops for global food
security, it will be essential to maintain a continuity of these plants species along with
the increasing environmental stress and to provide opportunities for the farmers to
breed more amount of crops that can be cultivated under unfavourable conditions such
as poor soil, salinity, drought, flooding, and extreme temperatures.

11. ROLE OF TREES/PLANTS : PRACTICAL
AND COMMERCIAL VALUE
• Support and sustain life throughout our
existence.
• Have a wide variety of practical and
commercial uses.
• Wood was the very first fuel, and is still used
for cooking and heating by about half of the
world's population.
• Provide timber for building construction,
furniture manufacture, tools, sporting
equipment, and thousands of household
items.
• Wood pulp is used to make paper.
• Bark of some trees can be made into cork
and is a source of chemicals and medicines
• Quinine and aspirin are both made from bark
extracts.
• Inner bark of some trees contains latex, the
main ingredient of rubber.

12. INVEST IN PLANT FOR SUSTAINABLE
EARTH
• Plants maintain the atmosphere by producing
oxygen and absorbing carbon dioxide during
photosynthesis. It also supports the ozone layer
that helps save the earth's life from damaging UV
radiation.
• Plants are one of Earth’s most essential species.
Every living thing - either indirectly or directly - is
supported by plants.
• The contributions of plants are numerous, from
the food we eat to the medicines we use and the
oxygen we breathe.

13. BENEFITS OF TREES/PLANTS
• Trees/Plants combat climate change.
• Trees/Plants clean the air.
• Trees/Plants provide oxygen.
• Trees/Plants cool the streets and the city.
• Trees/Plants conserve energy.
• Trees/Plants save water.
• Trees/Plants help prevent water pollution.
• Trees/Plants help prevent soil erosion.

14. NEED FOR PROTECTION OF PLANTS
FOR SUSTAINABLE EARTH
• Role in the Ecosystem: Plant species form the basis of
almost all ecosystems.
• Ecosystem Services: Plants provide several provisional
and cultural services. Provisionally, various species provide
a substantive amount of the world’s food, such as fruits,
nuts, and agricultural crops.
• Economic Contribution: Plants are an extremely valuable
economic commodity.
• Uniqueness: Plants are unquestionably some of the
world’s most visually stunning and captivating species. But
plants mean so much more than just their visual beauty.

15. WAYS FOR SUSTAINABLE EARTH DAY
• Follow the 3 R's. Look for ways you can Reduce,
Reuse and Recycle throughout your home.
• Attend an Earth Day fair.
• Get plugged into a group.
• Make a recycling plan.
• Fix those leaky faucets.
• Plant a tree.
• Find a carpool service.
• Give up bottled water.
• Start buying local.
• Go paperless.
• Turn off the tap.
• Conserve energy at home
