1. Avoiding Interference of Highways
According to the new circular to National Highways Authority
of India (NHAI), National Highways and Infrastructure Development Corporation
Ltd (NHIDCL) the construction of highways through ecologically sensitive areas
like wildlife centuries and national parks so that there is minimal
interruption in wildlife. To ensure this, any such construction should be done
after taking clearance from NHAI and NHIDCL.
If any other bypass/route is available even if longer should
be constructed to avoid any disturbance in national parks and sanctuaries.
2. Preventing England Rivers from
drying up by implementing Ban on Hosepipe:
Water level in various rivers of south east England has
reached below or severely below the normal levels. Last summer’s heatwave and
dry winter has worsened the situation.
To prevent the worsening of current situation various groups
have written to the chief executive of Environment agency to ban the hosepipe.
But the spokesman of agency considers that this decision will be premature as
the condition of rivers is not at critical level.
3. Agreement among G20 Countries to
tackle Ocean plastic waste:
In a meeting held in Japan, all the G20 countries have
agreed to control the plastic waste been produced that has been chocking the
seas.The progress would be reported every year. The attention would be given to
microplastics that can easily go in to food chain and would be having the worst
As only about nine percent of plastic is being recycled, the
long-term solution would be to produce less and use less. Countries like China
have already banned import of plastic.
So, all countries including developed and emerging economies are working
hand in hand to tackle the situation.
First meeting of G20 countries is supposed to be held in
Japan this November.
4. Divers as Saviors of Oceans:
A total of 633 divers have set the Guinness world record by
diving deep in to the sea and staying under water for about 15 minutes and
collecting the debris from sea floor.
The drill was performed near the Deerfield Beach
International Fishing Pier in Florida.
The amount of litter collected has not yet measured but
approximately 1600 pounds of lead fishing weights have been retrieved.The
previous record for underwater cleanup was set in the red sea in Egypt in 2015.
5. Seattle’s Green Fleet “Cleaning
Garbage with Garbage”:
Seattle is touching new heights in managing waste. Seattle
public utilities and waste management have officially gone green. Seattle along
with Recology have designed “GREEN FLEET” waste management vehicles that
operates via electrical energy, renewable natural biogas emitted from landfill
trash, diesel and vegetable oil, soybean oil. There is hope of getting 200
trucks by 2020.
The use of renewable gas will decrease the omission of
nitrogen oxides and greenhouse effect along with a considerable decrease in
noise pollution created by regular garbage trucks.
6. Gujarat’s War Against Air
introduced Emission Trading Scheme to control air pollution and is following
cap and trade program. This targets the emission control for Particulate Matter
pollutants in Surat’s industrial belt.
government has decided to allocate permits to companies specially the one prone
to emission of huge amount of particulate matter. To expend this project there
are multiple challenges that must be considered:
allocation of permits should be corruption free and transparent. Auction based
system can be followed but consideration should be given to smaller and medium
high cap should be put to make the industries adapt to the tightening
environment. To make sure that small industries are also getting benefited the
cap should be reduced every year. Highly polluting industries should be
identified (like India’s coal power plant) and should be included under this
7. Greenland Melting at an Alarming
the surface of Greenland ice sheet has started melting that is not usual for
this time of year. The temperature of Greenland is recorded to be rising 10-20
degree Celsius above normal.
increasing temperature there in spike in melting of ice sheet and as a result
45 percent of ice sheet surface has been melting. Ice sheet is usually covered
by snow that increases mass and reflects sunlight known as albedo effect. Due
to lower accumulation in winter and scorching summer these ice sheets have become
weaker. Wildfire soot and black carbon particleshave led to more absorption of
sunlight worsening the situation.
warming twice as fast as compared to the rest of the world. Due to this if ice
sheets completely melts away it would lead to rise in sea level by 24 feet.
8. Air Pollution in India Causing
Decrease In Life Span:
pollution and the deadly diseases caused by it have become the third highest
cause of deaths in India.
exposure to outdoor particulate matter, ozone and household air pollution in
south east Asia has caused a reduction in life expectancy by 2.6 years. As it
causes chronic diseases such as Chronic obstructive pulmonary disease (COPD), lung
cancer, ischemic heart disease, diabetes, dementia, infertility, bladder
cancer, abdominal organs, liver problems.
ultrafine particles of pollutants can penetrate to the cellular level so
potential risk to each organ of the body.
9. Plastic particles in Food Chain:
In a recent
study of small number of foods and drinks it has been estimated that humans
ingest around 50,000 particles of microplastic per year. Actual number might be
on the higher end as only few food samples were used in study.
Few of these
microparticles are small enough to penetrate the human tissues and might
release toxic substances in lingterm. It might lead to stimulaton of an immune
litter gets disintegrated in small microplastic particles and gets incorporated
in air,soil, rivers and even oceans. The microplastic pollutnts from air gets
inhaled and have potential to cause irreversible health hazard. Saying no to
plastics can control the situation up to some extent.
10. England 71% Short of Targeted Tea
government has set a target of planting trees in 5000 hectares to combat with
climate change crisis but only 1420 hectares were planted. According to
Committee on climate changes around 1.5 billion of trees would be needed by
2050 suggesting that15% of the crop land has to be used for planting trees and
growing plants to obtain fuel.
England are not getting enough support from government for tree plantation. The
woodland trust claims that if the get enough government support the target of
17% tree cover is achievable. More trees in country can ensures zero emission
along with providing timber, reducing floods and protecting wild life. To
address these environment priorities new environmental policies are must.
11. $20 Million Penalty for Carnival
Cruise for Environmental Crimes:
corporation agreed to pay a penalty of $20 million for environmental violation
such as dumping plastic waste in the ocean. Along with this a fine of $10
million per day will be imposed if they fail to restructure the corporate
Miami based carnival has polluted Bahamian
waterswith plastic mixed food wastes.
a long history of polluting water bodies by dumping plastic wastes and oily
discharges from ships, but they have never improved their policies and continue
to destruct the ecosystem.
Caribbean princess Ship has illegally dumped the oil waste straight in the
ocean and has tried to hide it from the investigators.
12. Violation of Court Orders
Obtained by BP:
are found to oppose court orders by sending their ships to join the protest.
Greenpeace has done it repeatedly and illegally. Around 40 people have been
arrested for continuing protest at the rig. Transocean a US oil contractor owns
the rig. The rog blew up in 2010 killing 11 oil workers. After that the protest
has started and everyday people are getting arrested for the same.
13. Special Devices to Explore the
Melting Patterns of Greenland Ice Sheet:
scientists havedevisedCryoegg to study the behavior of meltwaters that runs
beneath the ice.Cryoegg is basically a 1.2 kg, 120mm diameter sphere with three
sensors for temperature, pressure and conductivity. It also contains a radio to
transmit data from thick sheets of ice.
meltwaters act as lubricant for the flow of glaciers and can lead to increase
volume of ice going to oceans. This might lead to increase in sea levels by 7m.
can record the activities going on beneath the thick sheets of ice hence giving
a clearer picture of extent of negative impacts.
the two locations of the project are EGRIP site in northeast Greenland and
Responder site at store Glacier in west.
14. Airbus All Set to Adapt Hybrid
System by 2035:
focusing on reduction of its carbon footprints, that is the reason they are
about to bring hybrid electric airliners in next fifteen years. They are
planning to start with the smaller single asile propulsion system and will
consequently move to the size of A321neo.
this might lead to about 75% reduction in CO2 emission. Currently airbus has
successfully made a hybrid engine that can develop 2 megawatts of pawer. This
type of engine might get mounted at the back of the plane to charge a battery
as well as producing its own thrust.
The main aim
of airbus is towards zero emission aircrafts. But to achieve that first hybrid
system should be developed and completely functional. As the main source of
power will shift towards electrical energy the craft design should also
concentrate towards propulsion. Many other countries like Israel are also working
toward development of hybrid and fully electric smaller aircrafts.
15. Ban on Dolphin and Whale
Captivity in Canada:
A bill known
as Free Willy has been approved in Canada that says the breeding and captivity
of cetaceans such as whales and dolphins is now punishable with $200,000 fine.
The bill will exclude the injured or licensed for scientific research mammals.
at Niagara Falls that owns 61 of these animals has opposed the bill. But the
park has enough number of beluga whales that there would be no loss of jobs.
Vancouver aquarium also had cetaceans in captivity. Supporters have celebrated
the historical decision of Canada government.
16. Bee and Butterflies in Danger in
Biodiversity Date Centre has claimed decrease in population of bees including
bumble bee in short span. Along with this there is found to be long term
decrease in population of butterflies.
indirectly indicates the changing attitude towards wildlife protection. There
are around 52 indicators that point out the causes of this change in
biodiversity. The progress can be seen in around 31% of the indicators. This
data can in turn be used for making policies and setting goals for restoring
the biodiversity. Along with this it can also tell the effectiveness of policy.
This type of data can also increase awareness level in people. According to
NBDC director when the biodiversity is under pressure it becomes more important
to set such indicators.
17. Air Pollution in Brussels:
Millions of people
are getting affected by air pollution. These people have no idea that the air
they are breathing is of very low quality. This lack of awareness is because of
low number of monitoring stations.
(PM) increases drastically making air polluted and harmful as these fine
particles can penetrate up to cellular level. These can increase risk of heart
and lung diseases including lung cancer.
Due to very
less interest of public bodies in the field people are completed to use their
own particulate matter sensors. The data generated from these sensors makes the
tacklingof the situation easier. These devices help to understand when and
where the sir pollution is increasing or decreasing. The impact of Citizen
science project that includes use of private particulate matter sensors is
commendable and the government wants to use it to its full potential to tackle
the increasing air pollution.
18. Sunlight and Air as Fuel:
neutral fuels are integral part of aviation and marine transport.
dioxide that is released after combustion of these fuels along with water can
be converted in to syngas i.e. a mixture of hydrogen and carbon monoxide. The
only thing required for this conversion is solar energy.
The syngas thus obtained can be converted in to kerosene, methanol, hydrocarbons. This type of thermochemical process requires entire range of solar spectrum and high temperature to ensure high efficacy. The mini refinery at the roof of ETH Zurich can produce one deciliter of fuel using this process. The project needs to be made more economical so that it can be used at industrial level as well.
The whole process can be divided in to three conversions broadly: First is extraction of CO2 and water from the air. Secondly, thermochemical conversion using solar energy. Finally, liquefaction of water and CO2 into hydrocarbons inside solar reactor concentrating solar radiations by a factor of 3000.
