World Environment Day is celebrated annually on June 5th to encourage awareness about environmental protection issues. This year's theme is "Ecosystem Restoration" and it is hosted by Pakistan. The environment includes living things like plants and animals as well as non-living things like air, water, and sunlight that surround us and interact in complex ways. Human activities like pollution, deforestation, and greenhouse gas emissions are negatively impacting air, water, land, and climate. Addressing these challenges will help preserve biodiversity and natural resources for future generations.

2. WORLD ENVIRONMENT DAY
 World Environment Day is celebrated annually
on 5 June
 First held in 1974
 Celebrated for encouraging awareness
for protection of the environment and
awareness on environmental issues such
as marine pollution,
human overpopulation, global
warming, sustainable consumption and wildlife
crime for a healthy and better future.
 It is a global platform with participation from
over 143 countries annually.
 This year’s theme is "Ecosystem Restoration“
and the global host of this campaign is Pakistan.

4. ENVIRONMENT
 Environment means anything that surround
us.
 It can be living (biotic) like animals, plants,
microorganisms or non-living (abiotic) things
like air, water, sunlight etc.
 In the environment there are different
interactions
between animals, plants, soil, water and
other living and non-living things.

5.  In biology and ecology, the environment is all of
the natural materials and living things
 An example of interactions between non-living
and living things is plants getting their minerals
from the soil and making food using sunlight.
Predation, an organism eating another, is an
example of interaction between living things.
 Natural resources like fish, insects, and forests
are renewable resources because they come
back naturally when we use them.
 Non-renewable resources are important things
in the environment that are limited for example, ,
ores and fossil fuels like coal, petroleum

6. WATER

7. WATER RESERVIORS
 Oceans
 Rivers
 Lakes
 Ponds
HUMAN IMPACT ON WATER
 Dams
 Stream channelization
 Urbanization
 Deforestation

8. FOOD CHAIN WILL BREAK DUE TO DEFORESTATION

9. HUMAN IMPACT ON AIR
 Atmosphere
 Climate
 Weather
 Air consists of 78% nitrogen, 21% oxygen,
1% argon and other inert gases and carbon dioxide
 The atmosphere includes greenhouse gases such as
carbon dioxide, methane, nitrous oxide
 The ozone layer of the Earth's atmosphere plays an
important role in reducing the amount
of ultraviolet (UV) radiation that reaches the surface.

10. GLOBAL WARMING
 Climate change i.e
temperature, humidity, atmospheric
pressure, wind, rainfall, atmospheric particle
count and global warming caused by human-
made releases of greenhouse gases most
notably carbon dioxide
 It is clear the planet is warming and warming
rapidly. This is due to the greenhouse effect,
which is caused by greenhouse gases, which
trap heat inside the Earth's atmosphere

11. BIOCHEMICAL CYCLES
 Water cycle
 Oxygen cycle
 Carbon cycle
 Nitrogen cycle
Pollution, green house effect and global warming effected
above cycles largely and contineously effecting.

13. OXYGEN CYCLE

16. CHALLENGES
 Elimination of pollution and toxicants in air,
water, soil
 Preservation of biodiversity and protection
of endangered species.
 Conservation of resources such as water, land,
air, energy and natural resources.
 Halting human-induced global warming, which
represents pollution, a threat to biodiversity, and
a threat to human populations.
 Shifting from fossil fuels to renewable energy in
electricity, heating and cooling, and
transportation, which addresses pollution, global
warming

17. CHALLENGES
 Shifting from meat-intensive diets to largely plant-
based diets in order to help mitigate biodiversity loss
 Establishment of nature reserves for recreational
purposes and ecosystem preservation.
 Sustainable and less polluting waste
management including waste reduction (or even zero
waste), reuse, recycling, composting and anaerobic
digestion of sewage sludge.
 Reducing profligate consumption and clamping down
on illegal fishing and logging.
 Slowing and stabilisation of human population
growth.
