INTRODUCTION In many communities around the world, people are involved in forestry, firewood charcoal harvesting, timber and non-timber deforestation, large scale commercial use, more than half the terrestrial habitat of the world, clean water and other important It depends on various ecosystem services, 2002, Santangeli et al., 2013, Chhatre and Agrawal, 2009). However, forest biodiversity continues to suffer losses, which directly or indirectly contribute to changes in forest ecosystems, and in some cases irreversibly degenerate.
If forests are depleted, it is necessary to deal with the loss of biodiversity. Biodiversity is one of the main concerns of the Burundando committee in "Our common future". Brail has about 55,000 plants, accounting for 22% of the world. The Convention on Biological Diversity (CBD, 2010) reports that more than two-thirds of the net primary production of land and solar energy is forest converted to plants. Therefore, global checks to ensure the sustainable use of natural resources should be addressed swiftly.
One of the main reasons for the loss of biodiversity is that the natural habitat is destroyed. Wild plants and animals live in the fields, forests and wetlands are disappearing. Land was cut down to grow crops and build houses and factories. The forest is cut into trees and firewood. For example, between 1990 and 2005, the number of forest areas in Honduras has decreased by 37%. Contamination, overfishing and overfishing have also led to a decline in biodiversity. Global climate change - The recent rise in world average temperature related to human activity is also a factor. The temperature of the warm sea destroys fragile ecosystems such as coral reefs. Coral reefs can protect 3,000 species of fish and other marine life such as pelicans and starfish.
Climate change is estimated to be a major factor in the loss of biodiversity in coniferous forests, savanna, Mediterranean climate system, tropical forests, arctic tundra, and coral reefs. In other ecosystems, at least in the short term, land use change may become a more important element in the loss of biodiversity. From 2050 onwards, climate change can be a major factor in the loss of global biodiversity. Literature evaluation by Fischlin et al. (2007) contains a quantitative estimate of the number of endangered species for climate change. With moderate confidence, if the global average temperature exceeds 2 - 3 ° C, about 20 - 30% of estimated species of animals and plants (in unbiased samples) may face temperature rises It is presumed. High extinction risk temperature level before industrialization
