5. Do you agree that everyone wants to
live in a safe world?
Where we can breathe fresh air
everyday.
We can consume clean water
Enjoying nature for what it is

7. ❑Environment
▪ A sum total of all the living and
non-living elements and their
effects that influence human life.

9. Thomas Malthus was an 18th-century British
philosopher and economist noted for the
Malthusian growth model, an exponential
formula used to project population growth.
The theory states that food production will
not be able to keep up with growth in the
human population and it would lead to:
▪ Disease
▪ Famine
▪ War
▪ Calamity

14. Land pollution refers to the
deterioration of the
earth’s land surfaces, at
and below ground level.
CAUSES:
• Litter
• Littering, the improper disposal of waste
products, is unfortunately common.
• Urbanization and Construction
• While urbanization is not in itself littering,
large quantities of people living, producing
trash and littering in a dense area does
inevitably lead to land pollution.
15.
16. CAUSES:
• Urbanization and Construction
• Construction activities, result in large waste
materials, such as metal, plastic, wood, and bricks.
• Loss of natural habitats of other species.
• Mining
• This extraction and the methods used in mining,
deplete the earth of its natural resources and
cause damage and pollution in its wake.
17. • Health risks, due to an unsanitary environment.
• Polluted soil, which leads to a loss of fertile land for
agriculture.
• The endangerment and extinction of species in
wildlife.
• Habitat shifting, where some animals are forced to
flee where they live in order to survive.
• Climate change, which causes an onslaught of
disastrous problems, including flash floods and
irregular rainfalls.
18. The release of substances into subsurface
groundwater or into lakes, streams, rivers,
estuaries, and oceans to the point where
the substances interfere with beneficial use
of the water or with the natural functioning
of ecosystems.
CAUSES:
❑ Industrial Waste
❑ Many industrial sites produce waste in the form of toxic chemicals and
pollutants, and though regulated, some still do not have proper waste
management systems in place.
❑ Marine Dumping
❑ Dumping garbage into the waters of the ocean. Household garbage is still
collected and dumped into oceans by many countries across the world.
❑ Sewage and Wastewater
❑ Harmful chemicals, bacteria and pathogens can be found in sewage and
wastewater even when it’s been treated. Sewage and wastewater from
each household is released into the sea with fresh water.

20. Major Oil Spills that have happened in the past 10 years:
• 2020 – MT New Diamond (2 million barrels of oil caught fire off the
coast of Sri Lanka in September with one of the 23 crew members
presumed dead)
• 2020 – Wakashio a Japanese bulk carrier, struck a coral reef off
Mauritius’ coast in the Indian Ocean in July, spilling thousands of tons
of crude oil into the sea and choking marine life in a pristine lagoon.
• 2018 – Sanchi Tanker carrying 136,000 tonnes of Iranian condensate
collided with a cargo ship off Shanghai, caught fire and burned for a
week. All 32 crew onboard were killed. Japan’s Coast Guard said at
the time that oil which washed up on the shores of its southern islands
was highly likely to have come from Sanchi.
Oil Spills still happen hundreds or thousands
of time but in small increments
21.
22. • Ingesting microplastics
• A person may ingest microplastics via
drinking water or through eating
contaminated seafood.
• Consuming water contaminated by
sewage
• The WHO note that, globally, around 2
billion people use a drinking water source
with fecal contaminants.
23. Air pollution refers to the release of
pollutants into the air—pollutants which
are detrimental to human health and
the planet as a whole.
CAUSES:
“Most air pollution comes from energy use and
production”
• Burning fossil fuels releases gases and chemicals
into the air:
• Carbon Emissions released from vehicles.
• Carbon Emissions released from factories
24. CAUSES:
❑ Smog and soot
▪ Smog occurs when emissions from combusting fossil fuels react with
sunlight.
▪ Soot is made up of tiny particles of chemicals, soil, smoke, dust, or
allergens in the form of either gas or solids hat are carried in the air.
❑ Hazardous air pollutants
▪ A number of air pollutants pose severe health risks and can
sometimes be fatal even in small amounts.
❑ Greenhouse gases
▪ By trapping the earth’s heat in the atmosphere, greenhouse gases
lead to warmer temperatures, which in turn lead to the hallmarks of
climate change
25. What are other kinds of pollution?
NOISE RADIOACTIVE
LIGHT
26.
27.
28.
29. The dying out or extermination of
a species.
CAUSES:
This occurs occurs when species are
diminished because of external
forces
• Habitat Fragmentation
• Global Change
• Exploitation
30.
31. What is Climate Change?
How is Climate Change different
from Global Warming?
Climate change is a change in the
usual weather found in a place. This
could be a change in how much
rain a place usually gets in a year.
Or it could be a change in a place's
usual temperature for a month or
season.
Global warming is the long-term warming of the
planet's overall temperature. The excess heat in
the atmosphere has caused the average global
temperature to rise overtime, otherwise known as
global warming. Global warming has presented
another issue called climate change.

35. Ways to prevent pollution?
❑INDIVIDUAL
▪ To have proper waste
management.
▪ Throwing trash/litter properly
▪ The 3 R’s
▪ Reduced use of personal vehicles.
▪ Reduced use of plastic/plastic
bags.
▪ Use energy more efficiently
❑SOCIETY/COMMUNITY
▪ Individual actions done as a
collective will have a big impact.
▪ Awareness of the threat/dangers
of the different environmental
issues.

37. RA 8749 (Clean Air Act of 1999)
• Outlines the government’s measures to reduce air pollution and incorporate environmental
protection into its development plans. It relies heavily on the polluter pays principle and
other market-based instruments to promote self-regulation among the population.
• It sets emission standards for all motor vehicles and issues pollutant limitations for industry.
• Emission limit values are laid down by The Department of Environment and Natural Resources, Philippines
as ‘Implementing Rules and Regulations for Philippine Clean Air Act of 1999.
38. The Philippine Clean Water Act of
2004 (Republic Act No. 9275)
HIGHLIGHTS:
• How will water quality be managed?
• Management of water quality will either be based on watershed, river basin or water resources region. Water quality
management areas with similar hydrological, hydrogeological, meteorological or geographic conditions which affect
the reaction and diffusion of pollutants in water bodies are to be designated by the DENR in coordination with the
National Water Resources Board (NWRB).
• Who will manage these areas?
• Management will be localized. Multi-sectoral governing boards will be established to manage water quality issues within
their jurisdiction.
• Representatives of mayors and governors as well as local government units, representatives of relevant national government agencies,
duly registered non-government organizations, the concerned water utility sector and the business sector.

environmental authority that sets the
global environmental agenda, promotes
the coherent implementation of the
environmental dimension of sustainable
development within the United Nations
system, and serves as an authoritative
advocate for the global environment.

leadership and encourage
partnership in caring for the
environment by inspiring,
informing, and enabling
nations and peoples to
improve their quality of life
without compromising that
of future generations.
43. Environmental NGOs in the Philippines
• World Wide Fund for Nature
• The name of the
organization says it all. Their
projects don't only focus on
food, water, and climate,
but on wildlife as well. In fact,
they exert effort to ensure
the survival of the rarest and
most endangered species in
the country.
• Waves for Water
• The organization works with
leaders and partners to
provide clean and potable
water for communities here
and abroad.
44. Environmental NGOs in the Philippines
• Save Philippine Seas
• Part of the advocasea of Save
Philippine Seas is to promote
community empowerment,
environmental education, and
shark conservation. The org also
initiates citizen-led programs to
empower Pinoys towards
behavioral change.
• Earth Island Institute
• Earth Island Institute is an
international org that jumpstarts
programs focused on hyperlocal
and grassroots environmentalism.
Their local arm implements the
International Monitoring Program
(IMP) which ensures that the
country's top tuna companies
conform to industry standards and
practices.
