What is biodiversity? Why does it change? Why is it important to conserve it?
INTRODUCTION
Presently these days, lots of people live in urban areas. In this case they are separated from the environment. But another important reason why humans will always depend on the environment is because our lives depend on biodiversity. Meaning that we get clothing, medicines, food and furniture from other species. Just because that people rely on biodiversity they have to conserve biodiversity and can save it for future generations (www.scienceclarified.com). But before knowing all the damage this can cause to us, firstly we should know what biodiversity is. Why does it change? Why we have to conserve biodiversity? The aim of this essay is to answer these three questions, so in this paper I will try analyze most important things about biodiversity.
MAIN ARGUMENTS
The definition of biodiversity has many different connotations, description of species composition interactions between organisms and their environment (Orians, G. H. 1996, p.49). But the major definition of biodiversity is: the variety of life in all its manifestations (Lecture notes). This modern definition can sound like the variety of life on earth, variety of species, and the communities in which they occur. The major elements of diversity are: genetic, taxonomic, and ecological. The first one is Genetic (populations, individuals) – individuals of the same species. It means genetic variations between individuals in a single population and between populations of the same species. Genetic differences are the raw material of evolution. The second element of diversity is Taxonomic (Kingdoms, Phyla, Genera, Species - richness) – variety of species in a particular region. Taxonomic diversity assumes relationship of species with each other. Taxonomic diversity is very important in counting species. Species can be determined by taxonomic diversity. And the last one is Ecological (biomes,
