Sustainable development is a development that
meets the needs of the present without
compromising the ability of future generations to
meet their own needs. It contains within it two key
concepts (1) the concept of needs, in particular
the essential needs of the world's poor, to which
overriding priority should be given, and (2) the
idea of limitations imposed by the state of
technology and social organization on the
environment's ability to meet present and future
needs" (http://www.iisd.org/sd/).
As an organization under UN which is responsible
for promoting education, UNESCO adopted the
concept and infused it in the education sector.
Concerning its implementation, regarding achieving
SD goals, this organization proclaimed 2004-2014 as
Decade of Education for Sustainable Development or
DESD (UNESCO, 2005). This can be viewed from
three perspectives namely socio-cultural,
environmental, and economic (Ali, 214; Summers,
2013; Pradhan and Mariam, 2014):
• from the socio-cultural perspective, it is seen as
the attempts to fulfill human rights and achieve
national defense, world peace, national life
survival, gender equality, cultural diversity,
intercultural understanding, healthcare, and
prevention and management of harmful diseases
SD goals, such as HIV/AIDS.
• From the environmental perspective, it becomes
the attempts to utilize the natural resources
equally with regard to the future generations’
needs, climate change anticipation, changes in the
natural environment in both urban and rural areas
due to urbanization, and prevention of the
disasters which is triggered by human activities
such as forest exploitation causing floods and
droughts.
• From the economic perspective, it is seen as the
efforts to reduce poverty, to improve welfare, to
achieve sustained economic growth, and to
establish economic independence and national
competitiveness.
The current threats to the environment are related
to uncontrolled population growth, urbanization,
development of infrastructures triggered by the
expansion of development in urban and industrial
areas. This has resulted in the increase of land and air
pollution and problems related to volumes of garbage
or industrial waste and household trash, which can be
hazardous to our health. It has also increased the
society’s consumption on a global scale, causing the
rise of demands on raw materials, energy, and water.
It gives some implications dealing with degradation
of humanity, cultural and spiritual values.
The world change has certainly brought impacts
on the environment, which must be well anticipated.
The rise of the world population, described above,
triggers escalating the increase in the needs of food,
clothes, housing, and energy. Countries are
competing with each other to carry out the
development for fulfilling the increasing needs.
However, many of them still base their standards on
conventional development model, focusing only on
economic growth. In the conventional development
model, the achievements in form of increased
production of goods and services, which are the
elements of Gross Domestic Product (GDP) and
Gross Regional Domestic Product (GRDP), do not
accommodate the environmental aspect. Besides,
social development is also overlooked so that in many
aspects poor people are marginalized during the
development.
The use of fossil fuel (oil, gas, and coal) increased
tremendously with the modernization of the lifestyle
around the world. This has resulted in an increase in
carbon dioxide and sulfur oxide gas content in the
atmosphere, rising earth temperature and melting ice
in the poles. Its long-term effect may come in the
form of submersion of many seaside cities in the
whole world. It is necessary to know that the use of
fossil fuel may diminish the ozone layer, or even
create a hole on it, rendering life forms on Earth
vulnerable to ultraviolet radiations from the sun. Its
collective effect may threaten the very existence of
life on Earth.
Another issue that we need to be aware of is the
contamination of nature by waste products. Many
irresponsible businessmen dispose their toxic
industrial waste to improper places for their private
cost-saving reasons. In addition, thick smoke coming
out of factory chimneys or turbid solution containing
awful stench is disposed of a running river. These are
examples of environmental damages caused by
irresponsible behaviors in the development of
economy with no regard to the sustainability of
development or environment.
The types of industries prone to causing damages
to aquatic environment include vegetable oil,
chemical, textile, bottled drinks, canned meat, pulp
and rayon, soybean sauce, canned fruits, and wood
industry. Meanwhile, those which often cause noises
are metallurgy, zinc, iron industries etc. Dust and
ashes circulated around the factory area, like dust
from cement industry, chalk industry and toxic gas
from the aluminum processing factory can cause air
pollution. The toxic gas waste is absorbed by local
plants that are consumed by the human.
