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 when things change and either improve or get worse. This meaning has been taken from the Oxford Dictionary.
Thus, biodiversity crisis means the large number of different animals and plants are decreasing or in other word it’s facing extinction or becoming endangered. It also means that the large number of animals and plants are in a great danger.
LOSES OF BIODIVERSITY
Some species that are more vulnerable to extinction than others include species at the top of food chains, such as large carnivores. Endemic local species which is a species found in only one geographical area with a very limited distribution, species with chronically small populations, migratory species, species with exceptionally complex life cycles and specialist species with very narrow requirements are also the examples species that are more vulnerable to extinction than others based the website, www.counrysideinfo.co.uk/biodvy.htm .
The loses of an individual species may cause different effects on the remaining species in an ecosystem. The effects depend upon how important the species in an ecosystem. Some species can be removed without any apparent effect while the removal of key stone species may have enormous affects on the remaining species. Key stone species is species that will have enormous affects on the remaining species if it is removed.
WHY CONSERVE BIODIVERSITY?
To prevent the extinction of our biodiversity or endangered species, we shall conserve our biodiversity. But, what
