The melting of ice in
the Arctic due to global warming is increasingly worrisome. Each year, sea
levels rise by 1-3 mm. If not immediately anticipated, rising sea levels would
be dangerous for the survival of humans living on the surface of the earth. Even
more dangerous, some of the world's major cities are in danger of drowning due
to rising sea levels, fragile foundations, and groundwater suction. Here are
the eight major cities in the world that are threatened drowning.
Shanghai
1. Shanghai, China
Shanghai was once a
place surrounded by swamps. The need for shelter and the swelling population
makes skyscrapers more and more in the area. No wonder, every year the ground
level in Shanghai drops by half an inch. Based on the PBS data, ground level in
Shanghai fell by about 2.4 meters in the period 1921 to 1965. Experts predict,
land in Shanghai can no longer withstand the heavy burden of building on it. It
is predicted that one day Shanghai will drown if the Yangze River overflows.
Ho Chi Minh City
2. Ho Chi Minh City (Saigon), Vietnam
One of the most
populous cities in Southeast Asia is also threatened drowning. Decreased ground
level makes this area prone to flooding. Each year, the height of the flood
rises as high as 2cm.
Bangkok
3. Bangkok, Thailand
The head of
Thailand's National Disaster Mitigation Center, Smith Dharmasaroja, predicts
that by 2100 Bangkok will be the second Atlantis. The city will sink due to
several factors, such as: climate change due to greenhouse effect, rising sea
levels, coastal erosion, and land shifts. In addition to the city's low
location, Bangkok is annually flooded.
Mumbai
4. Mumbai, India
Not much different
from Bangkok, Greenpeace activist group reported that in 2100 the city of
Mumbai will be drowned by sea water. Rising sea water up to 5 meters causing
this city people in the city threatened its sustainability.
Mexico City
5. Mexico City, Mexico
This one city each
year sinks as deep as 20cm in case of flooding. It is located in the valley
plus a bad drainage system makes Mexico City threatened drown. Since 1975, the
city's drainage capacity has dropped 30 percent. But now the government is
working on the creation of a giant drainage tunnel that is claimed to hold
enough water.
New York
6. New York, United States
Rising sea levels
were also threatening the city in the United States. His position at the mouth
of the Hudson river that is connected directly to the Atlantic Ocean also
becomes the trigger. Science Daily predicts, seawater city is doubled compared
to other oceans. Not only that, coastal erosion, decline in soil layers and
environmental destruction can also trigger a waterspout in the city known as
the business center of the world.
Venice
7. Venice, Italy
End of 2012, the city
is inundated with severe flooding. This phenomenon is present due to a
combination of heavy rain and wind from the south. At least 70 percent of the
mainland in this canal city is flooded with a depth of up to 1.5 meters above
normal. The flood seems to be one indication that the Venetian region continues
to sink. The Christian Science Monitor even notes that the city has landed 30
centimeters in the past 100 years. Rising water levels in the Mediterranean Sea
add to the possibility that the city of the canal sank.
Jakarta
8. Jakarta, Indonesia
In addition to
geographical location under the sea surface, the need for high ground water is
suspected to be one of the causes of the sinking of mainland Jakarta. The
increasing population population is the main reason for the need for ground
water. In the next 20 years, it is estimated that the population in the capital
will increase to 40 million people.
The Dutch hydrologist
JanJaap Brinkman explains that if groundwater is being sucked continuously, at
the end of the 21st century, Jakarta will sink as deep as five to six meters.
Just waiting for the time Jakarta will sink under the sea as the city of
Atlantis.
These cities are
threatened by drowning due to rising sea levels and global warming. If we do
not change the way we treat the earth, those cities will be completely drowned
out without we can do anything. Let's start to care about the environment.
