titled “Loss of biodiversity and ecosystem balance” by Professor Dale F. Webber the importance of biodiversity in our ecosystem was explained and an even more detailed observation of the major threats to the biodiversity were highlighted. Of the twenty four top causes‚ climate change‚ environmental degradation‚ conservation issues and exploitation of energy reserves were deemed the most contributing. With the exception of climate change‚ which occurs regardless of the presence of humans on the earth

been projected to exist (Becher‚ 1998‚ 60). Tropical entomologist Terry Erwin’s research supports that there may be as many as 30 million insect species alone in the tropical rainforests (Shiva et al‚ 1991‚ 14). One of the true challenges to biodiversity is that there are so many species that we may be obliterating that we are not even aware exist yet. We are destroying species faster than we can identify them. Extinction and evolution are a normal part of the life cycle on Earth. Of all

Homework 6 – Siovhan Tan Referring to examples‚ discuss the threats to biodiversity hotspots and why these threats could prove critical (15 marks) Biodiversity hotspots are areas in the natural environment that contain some of the biggest concentration of flora and fauna in the world‚ often containing many rare and endangered species. However many of these ecosystems are threatened by the likes of climate change‚ increased urbanisation/land use and tourism developments which can prove critical

wildlife which includes native plants and animals‚ depends on protection of forests. Wildlife is the direct product of the land resources and habitat conditions. The neglect of forests moans the destruction of the wild animals. Wildlife‚ like we human beings‚ need food‚ water‚ and shelter. Destruction of forests‚ wetlands‚ marshes‚ points‚ grasslands etc. eliminates their sources of food‚ water and habitat. The National wildlife action Plan launched in 1983 provides the framework of strategy as

Natural resources are conserved due to economic as their natural beauty and importance to local culture. Preserving biodiversity is essential for ecosystems to respond flexibly to damage or change. An International treaty‚ the convention on International Trade in endangered species of wild Fauna and Flora (CITES) went into effect in 1975 and out lawned trade of endangered animals and animal parts

INTRODUCTION According to Oxford Dictionary‚ biodiversity means the state of having a large amount of different number of animals and plants which make a balanced environment. Biodiversity is also known as flora and fauna. The meaning of flora is all the plants growing in a particular area while fauna means all the animals of an area or a period of time. Rafflessia for flora while tiger for fauna is a case in point. Crisis on the other hand means a time of great danger or difficulty‚ the moment

As defined by the United Nations Convention on Biological Diversity‚ it includes diversity of ecosystems‚ species and genes‚ and the ecological processes that support them. Natural diversity in ecosystems provides essential economic benefits and services to human society—such as food‚ clothing‚ shelter‚ fuel and medicines—as well as ecological

Animals who can’t live or survive in certain regions either migrate or die. Common ancestors often link to present day organisms showing biologically and different

At present‚ Earth is experiencing the largest extinction to date‚ triggered by the increase of human activity in recent decades‚ which has been made inexorable succeeding population growth‚ making demands for food and fuel greater than ever. This has led to habitat loss‚ climate change‚ overexploitation‚ pollution and invasive alien species. Biodiversity loss is responsible for destabilizing ecosystems because it weakens their natural cycles‚ reducing the ecosystem’s productivity. It has impacted
