Alhamdulillah, bersyukur ke hadrat Ilahi kerana dengan limpah dan kurnia-Nya dapat saya menyiapkan buku skrap Biologi pada tahun ini tanpa sebarang masalah. Kesempatan ini,saya ingin mengucapkan ribuan terima kasih yang tidak terhingga kepada Guru Biologi saya, Puan yang telah banyak memberi bimbingan, tunjuk ajar serta panduan. Akhir sekali, buat rakan-rakan yang telah sama-sama menjalankan kajian ini serta bagi pihak yang terlibat ribuan terima kasih diucapkan. Tanpa mereka semua adalah mustahil bagi saya untuk menyiapkan tugasan ini.
Human Activities that Endangered an Ecosystem
DEFORESTATION * Deforestation is the permanent removal of trees from the forests.
EFFECT OF DEFORESTATION * Tropical rainforests are the oldest ecosystem on Earth and believed to be home to about half of the world’s flora and fauna species. * Rainforests play an important role in regulating the world’s climate. They are known as the ‘carbon sink’ of the Earth because they absorb vast amounts of carbon dioxide during the photosynthesis and the same time release oxygen into the atmosphere. * Large scale deforestation is thought to have a significant effect on soil erosion,flash flood,severe climatic changes and loss of global biodiversity. * Rainforests also serve as water catchment areas. Without proper planning and development,a land stripped of its vegetation cam rapidly succumb to soil erosion. * The absense of plant root systems makes the soil structure unstable. * When it rains heavily for a long period of time, the top layer of soil disintegrates easily and this leads to landslides esspecially on steep hillsides. * The eroded soil is then carried away by moving water and deposited at the bottom of rivers,which
