Orang berkata bahwa ilmuwan adalah orang yang dapat mengubah dunia, memajukan teknologi, selalu membuat suatu terobosan yang dapat memulai peradaban baru. Hal itu terbukti dengan peradaban manusia yang semakin maju tahun ke tahun.
Dahulu orang berkirim kabar lewat surat yang seminggu kemudian baru dapat dibaca oleh orang yang dituju, sekarang oleh teknologi cangih yang diciptakan ilmuwan kawan di belahan dunia manapun dapat berkirim kabar dengan cepat dengan e-mail ataupun pesan singkat (short message sending).
Dahulu orang berjalan kaki atau bersepeda untuk pergi ke tempat kerja ataupun berjalan – jalan, kini oleh teknologi manusia tidak perlu repot berjalan kaki atau lelah mengayuh sepeda karena lebih dari 35% manusia (data tahun 1990 di eropa) menggunakan mobil untuk berpergian.
Dahulu orang menggunakan batu untuk menulis atau daun – daunan, sekarang industri kertas telah didirikan dengan kertas yang mudah didapatkan, digunakan dan dibuang.
Semua keuntungan ini ada di sisi manusia (Homo sapiens). Tapi sadarkah kita manusia, telah merugikan ribuan bahkan jutaan spesies di bumi ini karena kita?
Sinyal yang digunakan untuk telepon selular, ternyata mengganggu kehidupan lebah, berikut berita yang saya ambil dari Cuplik.Com :

sinyal ponsel mengganggu komunikasi
lebah yang juga menggunakan sinyal |
Cuplik.Com - New Delhi - Ponsel yang berkembang di masyarakat ternyata bisa menyebabkan penurunan tajam dari populasi lebah madu. Sebab sinyal dalam ponsel menyebabkan radiasi pada koloni Lebah.
Para peneliti India yang berasal dari University of Punjab telah melakukan sejumlah uji coba dengan memasang salah satu dari dua sarang dengan dua ponsel yang dinyalakan selama 15 menit selama dua kali sehari. Sedangkan sarang yang lainnya ditaruh ponsel mainan atau dummy.
Setelah tiga bulan, mereka menemukan bahwa jumlah lebah dalam sarang yang dilengkapi dengan ponsel telah jatuh secara dramatis. Lebah Madu berperilaku aneh, ada lebih sedikit telur, dan tidak menghasilkan madu.
Perubahan perilaku lebah serupa telah diamati di seluruh dunia dalam beberapa tahun terakhir. Koloni dari lebah-lebah tersebut hanya meninggalkan sarang, tidak pernah kembali. Fenomena ini dikenal sebagai koloni gangguan yang menyebabkan keruntuhan.
"Biasanya runtuhnya koloni sebelumnya disebabkan oleh virus, parasit, pestisida, menggunakan tanaman rekayasa genetik dan perubahan iklim," kata para peneliti, seperti dilansir Times of India,
"Laporan seperti runtuhnya koloni di alam di negara-negara berkembang seperti India, karena radiasi elektromagnetik (EMR) berbasis teknologi relatif baru bahkan cendrung tidak ada. Tapi, hal ini dimungkinkan bahwa EMR yang berlaku di negara-negara maju mempengaruhi populasi lebah di negara tersebut," tambahnya
Dari hasil penelitian tersebut, para ilmuwan di India menyimpulka, "Kami beruntung bahwa lonceng peringatan sudah berbunyi dan hal itu bagi kita dapat digunakan merencanakan strategi yang tepat untuk menyelamatkan bukan hanya lebah, tetapi hidup dari efek buruk tersebut,"[oz/mang].]
Limbah dari industri di dunia merusak lingkungan. berita dibawah ini diambil dari http://www.rainwaterharvesting.org/crisis/Industrial-pollution :
| | Industry at any cost
(This article first appeared in Down To Earth,
April 15, 2000)
Maharashtra and Gujarat. The brightest jewels in India's industrial crown. But impressive industrial growth figures fail to hide the grim realities of environmental pollution. While, the state governments are only bothered about industrial growth, the civil society is struggling to draw public attention to the impending danger to the environmental and public health. Industrial survey statistics tell you that more than one-hird — 36.3 per cent — of the total value added by to the raw materials through manufacture in the factory sector of the country comes from Maharashtra (23.66 per cent) and Gujarat (12.64 per cent). Easily, the two most industrialised states of India.Governments of both the states claim they have created immense prosperity in the region. But statistics do not tell you the real story of thousands of workers and farmers. Aniruddha Mohanty is one of them.
Mohanty has been working in the Daru Khana shipbreaking yard of Chembur for the past 15 years. It is a life without any dignity due to a living being. Everyday for 8-10 hours he inhales toxic fumes from the abandoned ships that he breaks. The fear of explosion looms large. His best friend died last month in an explosion while breaking a ship. “In the past 15 years, I have got tuberculosis three times. The doctors say I have to quit this job and to shift to a cleaner place,” he says. He stays in Deonar, Maharashtra's largest solid waste dumping ground. In violation of a Mumbai High Court order, prohibiting burning of wastes, wastes are still burnt in Deonar. For Aniruddha, clean air is an impossibility.
Drive down the Mumbai-Pune highway and you will witness the horrible truth of industrialisation. Hundreds of industrial units dealing with chemicals and fertilisers dump their sludge along the roadside. Chimneys emit gases that make breathing difficult. “Industrial units never stop polluting, and people cannot stop working for them. So, it is a treadmill that ends only with a painful death,” says Rajesh Panicker, an industrial worker of Panvel in Maharashtra.
A few hours of travelling northwards of Mumbai will take you to the Vapi Industrial Estate of southern Gujarat. At Kolak village, about 15 km away from the estate, you will get statistics of a very different kind. “Sixty people have died of cancer in the village in the past 10 years, while 20 others are fighting a losing battle,” says Ganpat B Tandel, former sarpanch (head) of the village council, who has been vehemently opposing pollution of the Kolak river by the industrial estate. Nearly 20 years ago, cancer cases were not so rampant. But factories of the estate, which produce pesticides, agrochemicals, organochlorines dyes and dye intermediates, have been dumping untreated effluents in the river. Most residents of the village are fisherfolk who eat fish from the river. “The organochlorines and other persistent organic pollutants (POPs) in the industrial effluents are known carcinogens,” says Michael Mazgaonkar of the Paryavaran Suraksha Samiti (PSS), a Gujarat-based non-governmental organisation. Take the case of Deviben Tandel, who had cancer. On December 31, 1999, when thousands of people who use products manufactured at Vapi would have been celebrating new year's eve, the 50-year-old resident of Kolak quietly died. Four months ago, her elder sister had died of cancer.
As per a Central Pollution Control Board (CPCB) action plan for Vapi, factories cannot dump effluent in the rivulet Bhil Khadi but have to send it to a common effluent treatment plant (CETP). “But hundreds of industrial units do not treat their wastes as per the inlet parameters of the cetp, and are releasing untreated effluents into the Bhil Khadi. It ultimately meets and pollutes the Kolak river and the sea,” says a cpcb official.
Nainabhen Tandel, sarpanch of the village council, says: “On many occasions, we have caught tankers directly dumping effluents in the river.” The fish catch in the coastal areas has gone down considerably. Says KH Makrani, vice-president of the Daman Fishermen Association in Valsad district of Gujarat, “We don't get fish catch in the seashore areas. So, only those fisherfolk who can afford to go as far as 12 km inside the sea are continuing in this business.”
There are innumerable stories like these that go unheard. Invariably, those worst hit by industrial pollution are either rural folk who are unaware of its effects or workers who earn their living from the polluting factories. But more than the polluting industrial units, the blame goes to regulatory agencies — state pollution control boards (SPCBs) and state industrial development corporations — that were created to control and monitor industrialisation. Instead, these agencies have been reduced to mere rubber stamps to promote industrialisation at a frenzied pace. The industrial system has been reduced to a state wherein it makes better business sense for industrialists to carelessly dump hazardous waste rather than set up mechanisms to deal with it.
So, what are the people doing to save themselves? Actually, not much right now.But, not too long ago, there was hope of battling out the pollution juggernaut through the courts and non-governmental organisations (NGOs). Finding out that there was absolutely no point in knocking at the doors of government agencies — there is a clear bias in favour of the industry throughout the government machinery — those affected by pollution rallied behind ngos. A spate of public interest litigation (PIL) saw the polluters being dragged to court. But the lack of initiative on the part of the implementing agencies tired out the public spirit. In 1995, the Gujarat High Court ordered the closure of 756 industrial units in Vatva, Narol, Naroda, and Odhav, asking them to compensate the villages affected by pollution through discharge of untreated effluents. Many of these units are operating even today and are still polluting. “The failure of the court had an extremely damaging effect as even the last institution of democracy failed to check pollution in Gujarat,” laments Girish Patel, an advocate in the Gujarat High Court.
In Maharashtra, the problem is componded by the absence of credible data. “It is difficult to find any data on the environmental status. The Maharashtra Pollution Control Board does not come out with any study on pollution. So the people do not have strong baseline data to contest the powerful industry lobby,” says TN Mahadevan, a scientist who is also the secretary of Society for Clean Air, a Mumbai-based ngo. “Lack of information paralyses the battle against pollution.”
At present, it's all quiet on the western front. And dirty. |

Lalu bumi memanggil kalian para ilmuwan, memanggil kalian wahai manusia yang dapat berfikir dan bertindak, untuk menyelamatkan dan mengobati lingkungan yang telah tersakiti (tercemari –red) oleh kalian sendiri.
Hari ini, saya mendapat penjelasan dari teman sekelas saya tentang “Apa yang dapat kita lakukan sebagai saintis untuk menangani pencemaran lingkungan?” dan saya mendapat jawaban seperti ini :
“Limbah yang merusak lingkungan pada jurnal tersebut berasal dari 3 tempat; limbah rumah tangga, bekas pertambakan, dan limbah industri, yang dapat kita lakukan adalah:
1.Untuk limbah rumah tangga : tidak membuang sampah sembarangan apalagi ke kali/sungai
2.Untuk bekas tambak : tidak menggunakan zat berbahaya saat menambak ikan
3. Untuk limbah industri : tidak membuang limbah secara langsung ke lingkungan (harus diolah terlebih dahulu)”
Menurut saya, pernyataan diatas adalah cara mencegah pencemaran, bukan mengobati lingkungan yang telah tercemar.
Apakah kita hanya bergantung pada industri yang mau mengolah limbahnya?
Apakah kita mahasiswa jurusan ilmu pengetahuan alam bergantung pada para penambak yang mau menggunakan zat ramah lingkungan untuk pakan ternak ikannya?
Apakah para saintis hanya bisa meneliti kadar pencemaran pada lingkungan, dan tidak dapat mengembalikan lingkungan menjadi sehat dengan ilmu yang mereka (atau kita-red) punya?
