3. Sustainable development, as that term is commonly
used and understood, means making continued economic and
social development more resource efficient and less
detrimental to the environment. But making development
more sustainable, while highly desirable, is not the same
thing as actually achieving sustainability. As we plan and
carry out human development programs we must ensure that
our aggregated demands upon the planet’s resources do not
exceed the earth’s capacity to supply them.

4. 15 GLOBAL CHALLENGES

5. 1. The first step in achieving true
sustainability is recognition of the total
scale of human activity. The global
footprint network estimates that we are
already using 150 percent of the earth’s
capacity to regenerate resources, and that
does not take into account non-renewable
resources, such as fossil fuels.

6. 2. The next step in achieving
true sustainability is acknowledging
the interconnectedness of all the
various subsets of
sustainability. Climate change,
energy, food, water, population, and
the environment are all inter-related,
and efforts to address one challenge
often exacerbate other global
challenges.

7. 3. The third and crucial
step is recognizing that our
failure to balance human
demands with the capacity of
the earth has serious
consequences for people today,
not just future
generations. Extreme weather
patterns and soaring food prices
are products of an over-heated,
over-subscribed planet, and
they are a sign that much worse
is to come unless we reduce the
total scale of human activity.

8. • WHAT IS GLOBAL
WARMING?
Global warming is the increase
of earth's average surface temperature
due to effect of greenhouse gases,
such as carbon dioxide emissions from
burning fossil fuels or from
deforestation, which trap heat that
would otherwise escape from earth.
this is a type of greenhouse effect.

10. Climate change, also called global warming, refers to the rise in
average surface temperatures on Earth. An overwhelming scientific
consensus maintains that climate change is due primarily to the human
use of fossil fuels, which releases carbon dioxide and other greenhouse
gases into the air.

11. THE CLIMATE CHANGE CHALLENGE
Research has shown that the level of
carbon dioxide (CO2) released into the
atmosphere has increased significantly
since the beginning of the industrial era.
Unless we do something to reduce the
amount of CO2 entering the atmosphere,
the world will experience the effects of
climate change.

12. What are the causes of climate change?
The primary cause of climate change is the
burning of fossil fuels, such as oil and coal, which
emits greenhouse gases into the atmosphere—
primarily carbon dioxide.

13. • Nina Glick Schiller defines
transnational as “those persons who
having migrated from one nation-
state to another live their lives
across borders, participating
simultaneously in social relations
that embed them in more than one
nation-state.”

14. OVERSEAS FILIPINO WORKERS
• An overseas filipino (filipino: pilipino sa
ibayong-dagat) is a person of Filipino
origin who lives outside of the
Philippines. This term applies to
Filipinos who are abroad indefinitely as
citizens or as permanent residents of a
different country and to those filipino
citizens abroad for a limited, definite
