Reflective journal 1

I learnt that biodiversity is very important towards our life .
Biodiversity is a range of life forms within a geographical region including plants and animals .From the biggest till the smallest .
Biodiversity is a portmanteau word which means it’s a word which formed from 2 different words .
Its formed by the word biology and diversity Biologists most often define "biological diversity" or "biodiversity" as the "totality of genes, species, and ecosystems of a region". An advantage of this definition is that it seems to describe most circumstances and present a unified view of the traditional three levels at which biological variety has been identified:
The current textbook definition of "biodiversity" is "variation of life at all levels of biological organization” .
Biodiversity is a broad concept, so a variety of objective measures have been created in order to empiricallyy measure biodiversity. Each measure of biodiversity relates to a particular use of the data.
For practical conservationists, this measure should quantify a value that is broadly shared among locally affected people. For others, a more economically defensible definition should allow the ensuring of continued possibilities for both adaptation and future use by people, assuring environmental sustainability.
As a consequence, biologists argue that this measure is likely to be associated with the variety of genes. Since it cannot always be said which genes are more likely to prove beneficial, the best choice for conservation is to assure the persistence of as many genes as possible. For ecologists, this latter approach is sometimes considered too restrictive, as it prohibits ecological succession .
This is what I learnt from my reading and research .
