Achieving the goals of the Paris
Climate Agreement will require action across all sectors of the economy, and
the finance sector is clearly fundamental. In fact, one of the Paris
Agreement’s three objectives is “making finance flows consistent with a pathway
towards low greenhouse gas emissions and climate-resilient development. Recent
announcements by some of the world’s largest financial institutions reveal an
emerging consensus that all fossil fuel investment and financing risks both
climate security and economic value. The finance sector has an important role
to play in ending further exploration and the expansion of fossil fuel
production.

THE BEGINNING OF THE END
2017 may
go down in history as the year when it frst became clear that the fossil fuel
era was fnally starting to sputter to an end. The cost of new solar and wind
power started to fall below the price of new coal and gas plants in a growing
number of regions. The CEO of NextEra Energy, one of the largest electricity
producers in the US, now predicts that “early in the next decade” — just a few
years from now — power will be cheaper from unsubsidized new wind and solar
plants in the US than from existing coal and nuclear plants. It’s still far from game over for the
fossil fuel industry, but the game hasdrastically changed.

TASTE—IT’S THE STRUCTURE THAT COUNTS
Why do certain
substances taste sweet, sour, bitter, or salty? Of course, it has to do with
the taste buds on our tongues. But how do these taste buds work? For example,
why does sugar taste sweet to us? The answer to this question remains elusive,
but it does seem clear that sweet taste depends on how certain molecules fit
the “sweet receptors” in our taste buds.

PROTECTING THE OZONE
Chlorofluorocarbons
(CFCs) are ideal compounds for refrigerators and air conditioners because they
are nontoxic and noncorrosive. However, the chemical inertness of these
substances, once thought to be their major virtue, turns out to be their fatal
flaw. When these compounds leak into the atmosphere, as they inevitably do,
they are so unreactive they persist there for decades. Eventually these CFCs
reach altitudes where ultraviolet light causes them to decompose, producing
chlorine atoms that promote the destruction of the ozone in the stratosphere
(see discussion above). Because of this problem, the world’s industrialized
nations have signed an agreement (called the Montreal Protocol) that banned
CFCs in 1996 (with a 10-year grace period for developing nations). So we must
find substitutes for the CFCs—and fast.

SCHOOL CHEMISTRY LABORATORY SAFETY GUIDE
Recognition of laboratory safety and health problems has crystallized
since the passage of the Occupational Safety and Health Act of 1970. This Act
requires that certain precautions be observed to protect the safety and health
of employees on the job. The employee designation includes all teachers
employed by private and public school systems in States that have occupational
safety and health plans accepted by the Occupational Safety and Health
Administration (OSHA) of the U.S. Department of Labor (DOL). OSHA rules and
regulations are provided to protect the employees and the facilities.

GUM THAT FOAMS
Mad Dawg chewing gum is
a practical joker’s dream come true. It is noticeably sour when someone first
starts to chew it, but the big surprise comes about ten chews later when
brightly colored foam oozes from the person’s mouth. Although the effect is
dramatic, the cause is simple acid–base chemistry.
The foam consists of sugar
and saliva churned into a bubbling mess by carbon dioxide released from the gum.
The carbon dioxide is formed when sodium bicarbonate (NaHCO3) present
in the gum is mixed with citric acid and malic acid (also present in the gum)
in the moist environment of the mouth. As NaHCO3 dissolves in the
water of the saliva, it separates into its ions:

NUCLEAR WASTE DISPOSAL
Our society does not
have an impressive record for safe disposal of industrial wastes. We have
polluted our water and air, and some land areas have become virtually
uninhabitable because of the improper burial of chemical wastes. As a result,
many people are wary about the radioactive wastes from nuclear reactors. The
potential threats of cancer and genetic mutations make these materials
especially frightening.
Because of its controversial
nature, most of the nuclear waste generated over the past 50 years has been
placed in temporary storage. However, in 1982 the U.S. Congress passed the
Nuclear Waste Policy Act, which established a timetable for choosing and
preparing sites for the deep underground disposal of radioactive materials.

BEST PRACTICES OF PEATLAND MANAGEMENT
BEST PRACTICES OF PEATLAND MANAGEMENT
Indonesia’s peatlands
have been utilized since the end of 19th Century. Prior to 1920, Dayak rural
communities in South Kalimantan have begun to manage shallow peatlands in the
area behind the river bank (back swamp) which they call the lawau and manage it
for rain-fed rice fields (Suwardi et al., 2005). The river area is a fertile
area because it is influenced by sediment runoff from rivers. Basically Dayak people
are very environmentally friendly. In managing the land, they have a rotating
farming system that always maintains a balance with the utilization process following
a natural cycle (Suwardi et al., 2005). They divide the lands into zones
comprising settlement, bushes, harvested paddy field (jurungan), dry paddy
field (pahumaan), plantations, sacred zones, and protected zones (kayuan).
Sacred zones are customary protected zones that should not be cleared for
agricultural land. When the agricultural land has become infertile, they will
move to look for similar land in other places. After being left for 1-7 years the
former fields will become bush and after 7-12 years the bush will become a
forest. They will reopen the former field after 30 years, when it has become a
forest again. This is done continuously and sustainably.

PEATLAND RESTORATION AGENCY: A SMART WAY TO OBTAIN A QUICK WIN
The Jokowi
Administration have seen that improving forest and land governance may take
times. Thus, it needs an acceleration and simultaneous actions to have results
in a relatively short period. In terms of fire prevention strategy, the
Government of Indonesia then established Peatland Restoration Agency (Badan
Restorasi Gambut/BRG) in January 2016, after the big fire incident of 2015. The
Agency is tasked to rehabilitate 2 million hectares by 2019, and the current
program is to carry out 2.49 million hectares restoration, which include 1.1
million ha to be performed by the Government and partners, while 1.39 million
hectares by relevant private companies. This agency focuses on rehabilitating
and restoring heavily degraded peatlands in fire-prone areas. Thus, this agency
supports the grand strategy for peatland management developed by Directorate of
Peatland Degradation Control, Directorate General for Pollutant and
Environmental Degradation Control, Ministry of Environment and Forestry.

PEATLAND MANAGEMENT AND SUSTAINABLE DEVELOPMENT GOALS (SDGS)
The ultimate goal of
the sustainable development goals is to end poverty, protect the planet and
ensure prosperity for all. Hence, managing peatlands should also comply with
the goals. However, managing peatlands to provide livelihoods for local
communities as well as to conduct intensive agriculture and forestry may
contradict with the protection of the environment. The options are whether
peatlands should be drained or to be sustainably managed.
