Why are forest considered biodiversity hotspots ?
olga2289 [7]

A hotspot, is a place with a hotter temperature in relation to its surroundings.

So, when we think of "biodiversity hotspot", what exactly does that mean?

It's a place with a higher biodiversity in relation to its surroundings, but also with more concentration of species.


So, that's why forests are considered a biodiversity hotspot. If you want some visual content, try finding a geographical map of Africa. In some desert regions you'll see green spots (some really big). These are forests.

The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.
