Semboyan 3R untuk Hidup yang Lebih Baik

Isu semacam global warming sudah tak asing lagi di telinga kita semua. Akan tetapi walaupun isu ini sudah sering di dengungkan masih banyak diantara kita yang menutup mata akan ancaman global warming dan semacamnya. Sering kali kesadaran kecil yang dapat membantu pengurangan effect global warmingpun lenyap karena kebiasaan kita menutup mata terhadap semua ini.

Sebenarnya relatif mudah bagi kita yang mau sedikit berusaha mengurangi efek global warming ini. Cara yang paling ampuh dan mudah adalah jangan buang sampah anda sembarangan lebih lanjut lagi buanglah sampah sesuai kategori sampah tersebut, organik atau anorganik. Hanya dengan seperti itu saja anda sudah bisa membantu bumi kita.

Jika semua masyarakat membuang sampah pada tempatnya maka lingkungan akan terlihat asri. Tidak kumuh, kotor. Selain itu apabila sampah dipisahkan organik atau anorganik akan memudahkan bagi kita untuk mendaur ulang (Recycle) sampah tersebut. Jika sampah kita tidak di daur ulang maka inilah yang akan terjadi.

Apa sih akibatnya ???

Mungkin jika sampah organik tidak di daur ulang kita tidak perlu khawatir karena sampah-sampah tersebut akan terurai oleh bakteri dengan mudah. Seperti penguraian sampah yang dilakukan Mycobacterium sp. atau Escherichia coli. Jangka waktu penguraiannya pun relatif singkat. 2 minggu sampai 1 bulan kemudian sampah organik akan terurai. Dan hasil penguraiannya berguna bagi tanah sebagai penyubur.

Yang dikhawatirkan adalah sampah anorganik. Yang tergolong sampah seperti ini ; plastik, kain sintetis, kaleng. Sampah-sampah seperti itu sangat sulit diuraikan oleh bakteri. Dibutuhkan waktu 5 tahun atau bahkan lebih bagi sebuah sampah anorganik agar terurai oleh bakteri. Bayangkan jika 1 triliun (1,000,000,000,000) orang di dunia membuang sampah anorganiknya sembarangan di tanah. Mengharapkan sampah itu akan terurai dengan sendirinya. Dalam 5 tahun saja bumi akan tertutup sampah anorganik dan mungkin manusia akan lenyap??? Apalagi jika hal itu benar-benar tejadi maka kualitas tanah pun akan berkurang dan kegiatan bercocok tanam akan semakin langka.

Cara mengantisipasi???

Oleh karena itu untuk mengantisipasinya bantulah orang-orang disekitar anda yang sangat mencintai lingkungan dengan membuang sampah pada tempatnya dan memisahkan sesuai dengan kategorinya. Atau mungkin jika anda sudah mulai tertarik untuk memelihara bumi ini lebih jauh lagi anda bisa menggunakan 3R.

Apa itu ???

3R adalah cara yang bisa dibilang ampuh untuk mengatasi masalah sampah anda.

Reduce

- Anda bisa mengurangi penggunaan barang yang tidak terlalu anda butuhkan (aksesoris baru dll. )

- Mengurangi penggunaan barang yang bisa merusak lingkungan. ( CFC pada parfum anda)

- Kurangi penggunaan kertas yang berlebihan. Gunakan tisu sehemat mungkin. Kalau bisa hindari pemakaian print preview.

- Baca koran online.

- Bila berbelanja bawa saja plastik belanjaan dari rumah agar mengurangi sampah plastik anda

Reuse

- Pemakaian kembali plastik yang anda miliki. Hal ini bisa membantu langkah penghematan anda.

- Pemakaian kembali kertas printan bolak-balik.

- Menyumbangkan baju bekas anda pada yatim piatu atau panti asuhan agar bisa di pakai lagi.

Recycle

- Yang paling mudah adalah mendaur ulang sampah organik di rumah anda dengan bantuan bakteri khusus tentunya.

- Menggunakan bekas botol plastik air minum, kaleng cat bekas sebagai pot tanaman.

- Mendaur ulang kertas

- Mendaur ulang sampah plastik menjadi barang bernilai ekonomis (tas dll. )

Epilog...

Cukup mudah bagi anda jika ingin melakukan semua itu. Sekarang semua tergantung niat untuk memelihara lingkungan yang ada di dalam diri anda. Apakah tekad anda sudah bulat???

Climate Change - A Threat to Humanity?

by Simone Poetscher

Global changes in climate and environment have become more important in our lives as we experience receding glaciers, melting polar ice caps and rising sea levels. Are these changes somehow related to the natural disasters of recent years? Were they the cause, or the consequence, of the enormous heat waves experienced in Europe and the United States or of the increase in the number and severity of hurricanes? How can we relate the traces of destruction left by, for example, El Niño and La Niña in South America, Australia, India, and Indonesia to these climatic changes?

Scientists believe that the climate has been constantly changing throughout history due to natural causes, but the impact of this change has never been felt in such tragic ways in recent years. Most scientists also agree that, in addition to natural causes, human activities have contributed to the growth of greenhouse gases in the atmosphere. Greenhouse gases are responsible for balancing the earth’s eco-system and for keeping the average global temperature on earth around 58.82°F (14.9°C). When more greenhouse gases are released, more heat is trapped in the atmosphere, just as it is in a greenhouse. The reason given for the increasing temperature on earth is that the atmosphere acts as a one-way blanket over the earth’s surface, absorbing longwave infrared radiation from the sun but rejecting thermal radiation from the earth. The result is an increase in temperatures and climatic changes.

Austria’s Contribution

Austria experienced some of these climatic changes when the 2002 floods along the Danube hit Salzburg and Upper Austria. Thousands of people were left homeless, and some lost their lives in the floods. A year later, Austria’s agriculture suffered from the hottest European summer of the century. While the average world temperature in the last 150 years rose by 33.44°F (0.8°C), the rise in temperature in Austria was more than twice as high, 35.24°F (1.8°C) over the same period of time. This rise has had an irreversible effect on Austria’s natural treasures: Glaciers have melted, and Austria’s areas of permafrost have decreased. The glaciers are now approximately half the size they were a hundred years ago. The Wurtenkees Glaciers in the Hohen Tauern have even lost three quarters of their size over the same period of time.

Austria recently gave its support to the efforts of the European Commission to raise awareness of climate change. As Presidency of the Council of the European Union, Austria took part in the European Commission’s anti-global warming campaign ‘You Control Climate Change.’ The campaign was initiated between May 30 and June 6 in all twenty-five EU member states. The goal was to inform individuals of how they can each make a contribution to fighting climate change. “Action against climate change is a priority. This campaign complements and reinforces our political and legislative efforts. It makes clear to which extent we all are responsible for climate change and what individuals can and need to do to limit this threat,” said José Manuel Barroso, President of the European Commission.

Austria’s efforts are also apparent on a global level. An amendment on climate change, the Kyoto Protocol, was signed in 1997 as a first step towards lowering the overall emission of six greenhouse gases. Currently, the Kyoto Protocol has been endorsed by 164 countries and covers 65% of the world’s greenhouse gas emissions. The protocol specifies that by 2012 there will be a reduction of six greenhouse gases by at least 5% below the level that existed in 1990. In order to achieve this overall reduction, each of the participating countries has been given a certain amount of standards it has to meet.

The Kyoto Protocol and the United States

The United States is the largest source of greenhouse gases worldwide. Although Vice President Al Gore signed the protocol on behalf of the United States in November 1998, the protocol was never submitted to the Senate for ratification. The following remarks were published in an analysis of the Kyoto Protocol by the current Administration which believes that the Kyoto Protocol is flawed: “The Kyoto Protocol fails to establish a long term goal based on science, poses serious and unnecessary risks to the U.S. and world economies, and is ineffective in addressing climate change because it excludes major parts of the world.”

The European Initiative

Each citizen of the European Union accounts for eleven tons of greenhouse gas emissions, mostly CO2, every year. This shocking number demonstrates just how important it is for every single person to change their behavior. “Turn down. Switch off. Recycle. Walk,” goes the slogan of the European Commission’s campaign, to remind us of the most commonly known steps to be taken for a healthy environment. Let us look at some surprising details and see which additional advantages come when CO2 emissions are reduced:

Did you know that putting wet laundry in a dryer produces over 6.6 pounds of CO2 emission for each drying cycle?

* Drying our laundry naturally saves energy and guarantees our clothes a longer life!

* Driving your car produces twenty-two pounds of CO2 emission for each gallon of fuel burnt. How about walking, riding a bike, car-pooling, or public transportation?

* Low-pressure tires require more fuel to overcome resistance. By making sure your tires have the correct pressure you could save 2.5% in fuel and CO2 emissions!

* Become creative in your garden and plant a tree! An average size tree absorbs over thirteen pounds of CO2 every year!

Emission reduction goals of the Kyoto Protocol apply to the following six Greenhouse Gases:

CO2 Carbon Dioxide
CH4 Methane
N2O Nitrous Oxide
PFC Perfluorocarbons
HFC Hydrofluorocarbons
SF6 Sulfur Hexafluoride
