Key issues facing Rio+20 By MARTIN KHOR

There will be no major breakthroughs in tackling global crises at Rio+20 but it can still be a success if the leaders can agree to reaffirm old commitments and launch some modest initiatives.

THIS week, up to 100,000 people are streaming into Rio de Janeiro for the year’s biggest international event – the UN Conference on Sustainable Development to be held on June 13-22.

It is more popularly known as the Rio+20 Summit, to commemorate the landmark Earth Summit of 1992, which placed the environmental crisis into the mainstream of political life.

Persistent problems in discussion Rio+20

Click to view the details

SINCE the world’s first big environment conference in 1972, green issues have become woven into the political agenda and into consumer consciousness. But as this snapshot shows, few problems have been resolved and some are worsening fast.

> Ozone protection: The 1987 UN Montreal Protocol outlawed chlorofluorocarbon (CFC) gases that erode Earth’s ozone layer, which protects the planet from cancer-causing solar rays.

Flush away the problem

By TAN CHENG LI star2green@thestar.com.my

Big plans are ahead to reduce sewage contamination in Sungai Klang.

EFFLUENT from sewage treatment plants has been singled out as a major river polluter. Just by sheer numbers alone, sewage treatment plants make up 49% (10,025 facilities) of the total number of water pollution sources found in the country.

In comparison, manufacturing industries make up 44.5% (9,069 sources), according to the Environmental Quality Report 2010 by the Department of Environment.

Lake of filth: The Sri Johor flood detention pond in Bandar Tasik Permaisuri in Cheras, Kuala Lumpur, not only holds excess water, but plenty of trash, too.

Saving Sungai Klang

By TAN CHENG LI star2green@thestar.com.my

The use of ‘soft rocks’ — heavy-duty geo-textile bags filled with sand and weighing two tonnes each — to protect the banks of Sungai Kerayong create a more natural riverine environment as plants can grow on them.

Long treated like a sewer rather than a river, can Sungai Klang be revived?

BY NOW, many people would have noticed that something is up in several rivers within the Klang Valley. In Ulu Klang, shady trees that line Sungai Klang have been sacrificed for slope protection works. Where Sungai Kerayong flows through Cheras, a water treatment plant is under construction. In Selayang, the banks of Sungai Gombak have been beautified.

Commercial wind energy generation may be possible after all

WIND ENERGY GENERATION – The model shows a 5-blade turbine

When talking about commercially producing energy from renewable sources in Malaysia, wind would come last, or even none at all. This is due to the fact that the country has low wind speed.

Malaysia’s mean annual wind speed is not more than 2 metre per second, when minimum 6 metre per second is needed to spin a wind turbine. Plus, wind speed varies according to month and region, making it an unreliable source for energy generation.

Let’s go beyond the Earth Hour

EARTH Hour was observed on March 31 by people across the country who profess concern for the environment and climate change. However, the fleeting and superficial nature of the event makes it of dubious educational and practical value.

Several organisations and corporate entities, however, must be commended for implementing environmentally responsible initiatives that go beyond the hour-long festivities. This includes banking group HSBC’s used battery collection programme scheduled to run until June 5.

The predicament of the public now, however, is where to dispose of used batteries for recycling after this programme ends.

It is common knowledge that batteries contain heavy metals such as mercury, lead, cadmium, and nickel, which can contaminate the environment when batteries are improperly disposed of.
