Deforestation is the permanent destruction of indigenous forests and woodlands. The term does not include the removal of industrial forests such as plantations of gums or pines. Deforestation has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area. Indigenous forests now cover 21% of the earth’s land surface. In a forest the crowns of individual trees touch to form a single canopy. In a woodland‚ trees grow far apart‚ so that the canopy is open.

which will be a main focus in restoring riverbanks. Fishing‚ recreation and pollution are a huge cause of the offset river balance and acidity as well as added nutrience and minerals‚ restoring the human induced damage will hopefully return the ecosystems back to their natural beauty. Unfortunately there are many nations around the world‚ which will be unfairly impacted from climate change due to their lack of adaptive capacity. A societies ability to adapt varies greatly within North America. Native

Why should tropical rain forests be conserved? Tropical rainforests are thought to posses more plants and animals than any other forests on earth. Most tropical rainforests are located around and near the equator‚ they have existed on earth for hundreds of millions of years. But they are among the most endangered ecosystems globally due to humans. They are an important part of human life and are know as the “lungs of the planet” they have many animals‚ and many natural medicines come from tropical

Indigenous people of the Amazon fostered palm forests‚ groves of Brazil nuts and fruit trees‚ and vine forests near ancient Amazonian settlements. Environmentalists could argue that rainforests can be “saved” by through the restriction of economic growth‚ but it is vital to realize that the local communities will not approve parks and reserves‚ as it is in their interest to conserve the rainforest. The shifted cultivator who forces small farmers into the forest to begin new farmlands causes about 60% of

PROTECTED AREA BY FOREST A protected forest is a specific term to denote forests with some amount of legal‚ and / or constitutional protection in certain countries. Forests have been used by humans since the beginning of civilization for hunting‚ harvesting trees and other activities. As populations grew there became a need to manage forests for the benefit of humans as well as the animals‚ plants and insects that live in them. Conservation forestry is the part of forestry that focuses on protecting

1.0 Introduction Last term the Biology and Geography class went to Hastings Point‚ New South Wales to visit three ecosystems found in the area‚ such as- mangroves‚ sand dunes and rocky shores. Hasting Points is the smallest coastal settlement of Tweed Shire. The hamlet is nestled between the ocean on its east and a delicate estuary on its west. This report will focus on the unique coastal habitats of Hasting Points and the various issues that challenge the sustainability of mangroves surrounding

deforestation must be based on practicality as well as feasibility in developing new policies for forest conservation‚ forest sustainability‚ and reforestation (Conservation International‚ 2010). New strategies need to be implemented because past efforts of rainforest conservation have failed‚ as proven with the rapid rise in deforestation in some regions. Closing the rainforest or making the forests into parks or reserves does not help the local economies‚ or give the locals any opportunities to

Declining Biodiversity Deanna Garrett ENV495 Jeanne Lambert May 6‚ 2013 Declining Biodiversity Biodiversity is important in ecosystems because every life form works together in order for them to function. When these ecosystems are disrupted or altered‚ or even lacks biodiversity‚ it poses major threats to all the life forms in it‚ whether it happens quickly or over a long period of time. These threats include atmospheric pollution‚ weather catastrophe‚ climate changes‚ or even man-made
