Beda Reboisasi dan Pembalakan Liar

Mesothelioma is a form of cancer which occurs in thin membranes (called the mesothelium) lining the chest, lungs, abdomen and sometimes the heart. Although quite rare, mesothelioma symptoms strike more than 200 people each year in the United States. The majority of mesothelioma cases are directly linked to asbestos exposure. Because of the long latency period of mesothelioma, the average age of patients is between 50 and 70 years. Mesothelioma affects men most due to the high exposure of asbestos in industrial typed jobs. Mesothelioma symptoms include respiratory problems, shortness of breath, continual cough and pneumonia. Other mesothelioma symptoms include weight loss, abdominal problems and swelling. In some mesothelioma patients, the mesothelioma symptoms are quite muted, making it hard for mesothelioma doctors to diagnose. Mesothelioma doctors specialize in the study, research, and treatments of Mesothelioma cancers. Mesothelioma (or the cancer of the mesothelium) is a disease in which cells become abnormal and replicate without control. During Mesothelioma, these cells will invade and damage tissues and organs. Mesothelioma cancer cells can spread throughout the body causing death. Mesothelioma treatments and Mesothelioma clinical trials and tests There are many mesothelioma treatment options available. Treatments include surgery, radiation therapy and chemotherapy and the mesothelioma treatment depends on the patient’s age, general health and stage of the cancer. There has been much mesothelioma research conducted throughout the past two years to find new treatment methods. Click here to read more about mesothelioma treatment techniques. Through mesothelioma research, The National Cancer Institute has sponsored mesothelioma tests and clinical trials that are designed to find new treatment methods. Because of the increase in number of mesothelioma cases in the United States, both governments have increased funding for mesothelioma research. Mesothelioma research and clinical trials have been successful in developing new techniques to fight this cancer and the outlook for more advanced mesothelioma treatments is promising. Surgery is the most common treatment method for malignant mesothelioma. Tissues and linings affected by mesothelioma are removed by the doctor and may include the lung or even diaphragm. A second mesothelioma treatment method is radiation therapy through the use of high energy x-rays that kill the cancer cells. Radiation therapy can be outside or inside the body. A third mesothelioma treatment method is chemotherapy. Through pills or drugs through needles, chemotherapy drugs are used to kill cancer cells. A new mesothelioma treatment method is called intraoperative photodynamic therapy. In this treatment, light and drugs are used to kill cancer cells during surgery for early stages of mesothelioma in the chest. Although there are numerous treatments and drugs for mesothelioma, doctors are losing the battle against this deadly disease. Most mesothelioma treatments involve old techniques combined with different drug cocktails. However, in most cases, these mesothelioma treatments have many side effects including organ damage, nausea, increase in heart failure etc. The rush to find a more effective mesothelioma treatment or even cure is ongoing at numerous clinical labs across the nation. Let's hope that the mesothelioma treatments will one day erradicate mesothelioma cancer and asbestosis.

Hutan adalah harta yang tidak ternilai, mengingat banyak kekayaan alam yang tersimpan di dalamnya.

Jika dikelola dengan baik, suatu negara yang hutannya luas, bisa mendapatkan banyak keuntungan.



Apasih sumber kekayaan utama hutan?

Tentu saja kayu.

Kayu adalah kebutuhan penting dan banyak dimanfaatkan oleh manusia untuk membuat mebel seperti meja, kursi, lemari.

Nilai ekonomisnya tinggi.

Tergiur dengan uang hasil kayu inilah sering terjadi pembalakan liar pada banyak hutan. Ini mesti dicegah dan jangan dibiarkan.


Pembalakan liar

Pembalakan liar adalah kegiatan menebang pohon di hutan yang serampangan atau sembarangan. Yang diincar hanya keuntungan semata.

Dalam beberapa waktu, puluhan hektar lahan langsung gundul.

Pohonnya lenyap.

Yang tersisa hanyalah onggokan tanah gersang.

Inilah mengapa pembalakan liar sangat dilarang dan pelakunya bisa kena hukuman berat. Hutan yang gundul tidak produktif lagi, tanahnya kering dan bisa menyebabkan longsor ketika musim hujan mengamuk.



Bahaya yang ditimbulkan oleh pembalakan liar antara lain :
  • Tanah menjadi gersang
  • Bisa menyebabkan longsor
  • Air tanah berkurang karena tidak ada pohon yang menahan air ketika hujan, sehingga air tidak bisa meresap.
  • Hewan kehilangan rumahnya
  • Pemasok oksigen berkurang
  • Mengurangi pemasukan negara



Hutan salah satu fungsinya yang vital adalah penghasil oksigen. Oksigen dibutuhkan semua makhluk hidup untuk bernafas.

Jika pohonnya diterabas tanpa perhitungan, jumlah tanaman ini berkurang drastis, sehingga pasokan oksigen berkurang dan udara disekitar tambah panas.

Kemudian pemasukan negara berkurang karena uangnya lari ke kantong para pencuri kayu ini.
Karena itulah, mesti dilakukan penangkapan terhadap para pelakunya agar hutan tidak sembarangan dibalak.

Sehingga kondisinya tetap hijau dan lestari.


Reboisasi

Kalau pembalakan liar bertujuan untuk mencari keuntungan dengan memangkas kayu sebanyak-banyaknya, maka yang ini adalah kebalikannya.

Reboisasi adalah kegiatan menanam pohon pada lahan hutan yang gundul.




Untuk apa melakukan reboisasi?
  • Mengurangi lahan gundul
  • Menambah jumlah pohon
  • Membuat hutan hadir kembali
  • Membantu menambah pasokan air tanah
  • Menjaga kelestarian hewan dan tumbuhan
  • Menjaga persediaan kayu agar tidak habis dan bisa dinikmati dalam waktu lama. 
  • Mencegah tanah longsor
  • Menjaga stok oksigen
  • Menambah pemasukan negara dan masyarakat sekitar


Hutan yang kembali bersemi berkat reboisasi mendatangkan banyak keuntungan, sudah disebutkan diatas beberapa diantaranya.

Menanam pohon itu butuh waktu lama..

Tidak seperti menebang pohon yang dalam hitungan jam langsung ambruk menghantam tanah.

Menumbuhkan pohon yang besar dan tinggi memerlukan waktu puluhan tahun. Sangat lama bukan? Karena itulah aktivitas menjaga lingkungan sangat melelahkan.

Tapi mengingat manfaat yang bisa diperoleh, ini mesti dilakukan terus.


Solusi

Agar hutan tetap lestari dan sekaligus bisa menambah pemasukan bagi negara dan masyarakat sekitar, tindakan yang terkonsep dan teratur mesti dilakukan.



Contoh tindakannya antara lain :
  • Menebang pohon yang sudah cukup umur
  • Pohon yang masih muda diberikan kesempatan untuk berkembang
  • Tidak menebang dalam jumlah banyak, misalnya harus dikontrol berapa pohon yang boleh hilang dalam satu hektar.
  • Lahan yang sudah hilang pohonnya segera ditanami dengan bibit baru



Jika ini dilakukan, kelangsungan hutan tetap terjaga.

Pohon tetap bisa diambil kayunya dan jumlahnya stabil karena terus ditanam pada lahan kosong atau gundul atau bekas penebangan.

Kelestarian hutan sangat sehat.

Tidak hanya kayu dan hewan saja yang merasakan manfaatnya, di hutan itu banyak juga tanaman obat yang bisa diracik untuk menyembuhkan banyak penyakit.

Peluang besar bukan?

Hutan itu menyediakan sumber daya yang banyak bagi hidup manusia, dengan pengelolaan yang bijak, banyak keuntungan yang bisa diraih..
