Answer:
I think climate change can be either fake or real. I do believe temperatures are rising, but if you look at the history of the earth, it's gone through many ice ages and changes, so I would assume that it is no big deal. There is no evidence that temperatures are rising at a deadly rate, but weather has been unpredictable for a while now. Then again, these are my thoughts on climate change, so I'm not sure if I'm right or wrong. Hope I gave some useful information!
Explanation:
Biogeographical studies use information for various fields, such as evolutionary biology, geography, geology, and climate science to determine how organisms evolved through time and how the moving of tectonic plates resulting in forming continents, mountain ranges and islands has affected their distribution.
Studies in this field explain how organisms that now live on different continents are very closely related and how the flora and fauna of islands are connected to one of the closest continents etc.
All the populations living and interacting within a particular geographic area make up a biological (or biotic) community. The living organisms in a community together with their nonliving or abiotic environment make up an ecosystem.
