forest will die out as a forest becomes fragmented. As habitat fragmentation proceeds across a landscape‚ species requiring the habitat gradually disappear‚ fading out from one fragment to another. Essay Question 2 What are the major causes of biodiversity loss (we talked about during lecture)? Why should we be concerned? Overall‚ scientists have identified four primary causes of population decline and species extinction: habitat loss‚ invasive species‚ pollution‚ and over harvesting. Global

These are specific to the chalk grasslands and there only being 19 sites of chalk grasslands shows just how rare the species are. In the creation of this ecosystem human interference is far more important because if natural succession were allowed to occur then many of the ecosystems would not exist and the biodiversity of the area would suffer.

Furthermore‚ the provision of novel habitat (hard substrata) along sedimentary shores can alter local and regional biodiversity by modifying natural patterns of dispersal of species‚ or by facilitating the establishment and spread of exotic species. 3. Attempts to use ecological criteria to solve problems of urban infrastructure are promising. Incorporating natural elements

Our life-support system’s is maintained by all the species that make up the biosphere-biodiversity. The survival of all these species are interconnected and dependent on each other.
