For individuals:
1)
Individuals should
use
less
p
ackaging
and
pay
attention
to
where
they
throw
away
the
rubbish.
2)
Individuals
can
also

Expected results:
1)
Less
packaging
and
fewer
products
are
a
step on
the
way
to
more
sustainable
development.
2)
If
rubbish
is
picked
up
from
th
e
beach,
it
will
not
flow
out
to
the
ocean
and
cause
problems for
animals
that
ea
t
it
or
become
trapped in
it.
)Interactive activity 2: Retell the suggested solutions to the waste problem in the ocean with the help of the diagram.
Solution 1 For organisations: Organisations like Ocean Conservancy have organised International Coastal Clean-up. Expected result: By cleaning up rubbish you are protecting the ocean environment and the animals that live there.
II. Critical Thinking
Interactive activity 3: Discuss the criteria for evaluating the feasibility of a solution.
The Criteria for the Feasibility of a Solution
□ Is the cost of time, money or energy within a reasonable range
1 / 3
□ Can it be done in practice
□ Will it be effective
…
(
Problem with the
earth
)Interactive activity 4: Discuss in groups, illustrate the consequences of global warming and think of the solutions and the expected results based on the diagram.
Problem: Global warming Consequences: Global warming increases the possibility of extreme weather events, accelerates the melting of ice caps and the rise of sea level, etc.

For organisations:
1)
Organizations
like
China
Environmental Protection
Foundation
have
organised
“Automotive
Environmental
Innovation
Leadership
Program
”
.
Expected
Result:
By
this
progra
m,
more
eco-friendly cars will be
developed.
2) Ant
Financial
Service
Group
has
launched
Ant Forest program.
Expected
result: Ant
Forest
has
motiva
ted
a
half-billion
people
to jointly
protect
the
environment
by
turning
the
ir
green
deeds
into an afforestation
campaign.
)Solutions to the problem
Solution 2 For individuals: 1) Individuals can reduce waste by choosing reusable products instead of disposables. Expected result: By recycling, you can save the resources. 2) You can reduce the use of electricity, water and gas, like taking public transportation instead of private cars. Expected result: By reducing the use of electricity, water and gas, you can save energy and reduce your greenhouse gas emission.
Conclusion: If we all make efforts to reduce greenhouse gas emission, global warming will be slowed down and the environment will be more pleasant.
(Answers may vary.)
Interactive activity 5: Present ideas and make comments on the feasibility of the solutions based on the criteria.
