Mê Kông cạn cá

BVR&MT – Tbong ngồi trong bóng râm của căn chòi tạm bợ trên bờ hồ Tonlé Sap, quanh anh là mấy đứa trẻ tò mò.

“Cá quả, cá trê, cá tai tượng… Trước đây, cách đây rất lâu, hồ có rất nhiều cá”, anh vừa nói vừa nheo mắt vì nắng.

Nhưng mọi thứ thay đổi chóng vánh. Các loài cá suy giảm, thực vật đang chết dần và toàn bộ hệ thống sông Mê Công tan rã. Đối với những đứa trẻ tụ tập quanh Tbong, một Tonlé Sap trù phú chỉ còn trong chuyện kể.

Nằm ở trung tâm lưu vực hạ nguồn sông Mê Công, Tonlé Sap là hồ nước ngọt lớn nhất Đông Nam Á. Hồ và vùng ngập lũ xung quanh được UNESCO công nhận là khu dự trữ sinh quyển vào năm 1997, là nơi sinh sản, cung cấp nguồn thức ăn và là nơi thu hoạch hàng trăm loài cá và các sản phẩm thủy sản khác.

13 Facts About the Controversial Massive Chinese Dam That Slowed the Earth’s Rotation

interestingengineering.com

The Three Gorges Dam is one of the most ambitious and equally controversial projects on the planet.

How much do you know about the Three Gorges Dam? You have probably come across dams through your travels, or there may even be a dam near your home town.

Dams can be awe-inspiring, human-made feats of engineering, powering the lives of the surrounding communities.

Yet, in the same breath dams are the subject of notable and significant national, regional or international controversy. And, no dam has garnered as much notoriety as the 3 Gorges Dam; a dam that is so massive in scale that it has actually slowed down the earth’s rotation.

For the uninitiated, a dam is a large barrier built across rivers and streams to confine and utilize the flow of water for human purposes such as irrigation and the generation of hydroelectricity.

So, if you have always wanted to hear the story behind the Three Gorges Dam and what makes it so controversial, it is your lucky day. An efficient man-made monument to innovation, or a destructive monstrosity? Today you will decide. Here are thirteen facts about Three Gorges Dam.

The Dam Was Originally Sun Yat-Sen’s Idea

Often considered the father of modern China, Sun Yat-sen originally proposed the idea of the Three Gorges Dam all the way back in early 1919. Overthrowing China’s Manchu dynasty in 1922,  Sun Yat-sen sparked the revolution that would plant the seeds of what would eventually become the Republic of China.

In an article titled, “A Plan to Development Industry”, Sun Yat-Sen proposed the idea of constructing a dam that not only would help control the flooding of the Yangtze River, but also embody China’s “new might.”  However, it would be a while before the project would come into fruition.

Three Gorges Is Massive

Though some claim the Three Gorges Dam is viewable from space, this is not true. Nevertheless, the dam is massive.  Made of steel and concrete, the steel dam is 7,661 feet long, almost 600 feet high.

Engineers needed 510,000 tons of steel to construct the massive dam. To put that in perspective, with the same resources you could build sixty different Eiffel Towers.

10 Big Changes for Forests Over the Last Decade

globalforestwatch.org

The last decade was pivotal for the world’s forests. The 2010s saw the rise of unprecedented new commitments — from governments and the private sector alike — to bring deforestation to heel. The UN REDD+ framework, the New York Declaration on Forests and the Sustainable Development Goals set out ambitious targets to conserve and restore millions of hectares of forests.

But as this decade ends and a new one begins, it is also clear the world has fallen short on achieving its forest goals. While the impacts of climate change are being felt around the world, forests — an invaluable climate mitigation tool — are still being lost at high rates. Leaders in key countries are back-tracking on forest protection. Tiếp tục đọc “10 Big Changes for Forests Over the Last Decade”

Quiet is a luxury in Vietnam

It was in the middle of the night when I was woken by a noise that kept thumping into my ears. Someone was playing music somewhere down the street, and it was understandably annoying. Everyone in the neighborhood started calling each other to find out who did it. As for me, there went my peaceful slumber.

Eventually, it was discovered that a café down the street was responsible for the noise. The music continued for about 20 minutes before dying out.

The next morning I asked the café owner why he played loud music when everyone was asleep. “It’s the World Cup!” he said, as if that explained everything. He thought that way he could attract more customers to watch the game.

The other week I and my friends were hanging out at Saigon’s Le Van Tam Park at around 7 p.m. It was quiet, away from the urban cacophony and the traffic. We were having fun until we heard music being blasted at maximum volume from the center of the park. A man was carrying a huge loudspeaker and cranked it all the way up, much to the dismay of passersby. I asked him to turn it down, and he said no. We had to move to another place in the park, as far away from the source of the noise as possible, but it kept ringing in our ears so much we couldn’t hold a proper conversation.

Ironically, we were discussing how a society where people cooperate with each other in public is healthier than one whose citizens keep dragging each other down through distractions. Having lived in Saigon for many years, I realized two problems that its administration kept ignoring: waste and noise pollution.

According to the broken windows theory by social scientists James Q. Wilson and George L. Kelling, visible signs of crime, anti-social behavior and civil disorder create an urban environment that encourages further crime and disorder, and vice versa.

One thing I noticed about Vietnam is how people have so little respect for each other’s ears. They don’t stop to consider if their playing music and singing loudly affects others, and the concept of noise pollution is simply lost to some. Every night I could hear the sound of people singing karaoke and eating and screaming during their nights out until 2 or 3 a.m. It’s almost lawless. Mind you, there’s an entire neighborhood here. Everyone’s trying to get some downtime after a long day at work or school. So please keep it down. I insist.

Surfacing Innovative Solutions for Reducing Marine Plastic Pollution

Over 8 million metric tonnes (MMT) of plastic leaks into the oceans every year. Approximately 80 percent of this comes from land-based sources such as beach litter and sewage effluent, including waste entering through rivers. About 60 percent of land-based plastic waste leakage originates in five countries, all of which are in Asia: China, Indonesia, the Philippines, Thailand and Vietnam. In a business-as-usual scenario, these countries are likely to more than double their plastic waste by 2025.

This study evaluates solutions available to reduce marine plastic pollution in Indonesia,the Philippines, Thailand and Vietnam. The insights cited in this report are based on deskbased reviews and semi-structured interviews conducted with AVPN members and a range of social purpose organisations (SPOs), including nonprofits and social enterprises.

People have to stand patiently in a long queue to enter Hanuel Park on Nanjido Island on a branch of the Han River in Seoul, South Korea.

None of them, neither adults nor children, seem frustrated to be queuing.

That’s probably because they know once they pass the entrance gate, they will step into a relaxing space with immense fields of flowers, wild grass, full of fresh air and tranquillity.

It’s a familiar scene at the park, which receives thousands of visitors a day. Tiếp tục đọc “Dump-turned-park offers relaxing moments”

Ngày 28/12, ông Võ Văn Chánh dẫn đầu đoàn kiểm tra, thị sát khu rừng đồi 90 xã Phú Lý, huyện Vĩnh Cửu (thuộc diện quản lý của Khu bảo tồn Thiên nhiên văn hoá Đồng Nai). Gần một hecta rừng tự nhiên tại đây có 61 cây đường kính 14-60 cm vừa bị đốn hạ với hơn 12 m3 gỗ.

Cùng lực lượng chức năng mất khá nhiều thời gian xem xét quy mô rừng thiệt hại và số gỗ bị đốn hạ, ông Chánh cho rằng sai phạm đã quá rõ, còn vi phạm đến mức nào thì phải điều tra thêm. Sau khi cùng đoàn kiểm tra ra về, ông Chánh một mình quay lại khu rừng tìm hiểu, xác minh thêm. “Đồng Nai lâu nay bảo vệ và quản lý rừng rất chặt chẽ. Giờ xảy ra việc cây rừng bị đốn là rất đáng tiếc, phải xử lý nghiêm”, ông Chánh nói.

12 organizations specializing in health and environment together have called on Vietnam to scrap 14 new coal plants.

Concerned by the environmental and health toll that coal-fired power plants exact, leaders of 12 networks and non-government organizations collectively urged Prime Minister Nguyen Xuan Phuc to stop 14 coal-fired plants in Vietnam.

Among the signatories to the statement released Monday are Green Innovation and Development Center (Green ID), World Wildlife Fund (WWF), Vietnam Sustainable Energy Alliance, CARE International and Oxfam Vietnam.

The 14 projects, located in eight provinces – Quang Ninh and Bac Giang in northern Vietnam, Nghe An, Ha Tinh and Binh Thuan in central Vietnam, and the southern Long An, Tien Giang and Soc Trang – will have a total capacity of 17,390 MW.
