LATAR BELAKANG
BATUAN ULTRABASA :
1. TERSEBAR LUAS DI INDONESIA
2. SEBAGAI BAHAN BANGUNAN KURANG MEMENUHI SPESIFIKASI
3. PENGGUNAAN LAIN YANG LEBIH BERMANFAAT
EMISI GAS CO
2:
1. KEBIJAKAN ENERGI
2. MINYAK BUMI, GAS ALAM, BATUBARA
3. NEGARA BERKEMBANG
EFEK RUMAH KACA :
1. PEMANASAN GLOBAL
2. PERUBAHAN CUACA GLOBAL DAN LOKAL
3. PERUBAHAN EKOSISTIM
DIMANAPUN CUACA AKAN LEBIH
TIDAK/KURANG RAMAH
BEBERAPA METODA PERANGKAP GAS CO
