Hutan paya bakau berbeza berbanding 30 tahunlalu

KUALA LUMPUR: Hutan paya bakau di pesisir pantai negara banyak berbeza berbanding 30 tahun
lalu kesan pelbagai aktiviti, termasuk perbuatan manusia.
Pensyarah di Jabatan Sains Bumi dan AlamSekitar di UniversitiKebangsaan Malaysia (UKM), Prof
Madya Dr Muzzneena Ahmad Mustapha, berkata sekitar 1970, paya bakau dikesan berada jauh ke
dalam laut, tetapi hari ini ia sekadar berselerakan di pinggir laut.
"Terdapat banyak faktor yang mempengaruhi hutan ini, antaranya alam semulajadi seperti hakisan
arus air dan angin serta hakisan pantai.
"Selain itu, aktiviti manusia juga memberi kesan seperti penebangan bakau dan kejadian tumpahan
minyak seperti berlaku di Tanjung Tuan, Melaka," katanya kepada BH, baru-baru ini.
