"Habitat Fragmentation" Reflection

     Habitat fragmentation is the process by which habitat loss result in the division of large, continuous habitats into smaller, more isolated remnants. The activity we did in class was that we represented bears in a habitat, and had four different colored cards representing our genes. It was mating season, so each of us had to go around and collect a total of four cards that where the same color. Only two students, "bears",  died because they fell into inbreeding depression. They did not have a total of four cards with the same color. In the second round, a road was built to represent a habitat fragmentation, splitting us up. The game was repeated again to get four different colors this time in our section. Many more of us were kicked out. The third round was another habitat fragmentation, splitting us up even more and then the game repeated. This activity represented habitat fragmentation because in each round our space become smaller and smaller, separating us from each other, and only working with the few people in our area; we were unable to cross the "human developments" which resulted to fewer of us in the game. This activity reflects the actual event that is happening in our environment, limited biodiversity and species extinction. 
     Habitat fragmentation is effecting our planet because humans are continuing to alter the natural habitats of species causing more extinction. Not every species can adapt to change so quickly which results to a decline in biodiversity that later results to extinct. The other causes of  habitat fragmentation other then human development is natural processes such as the Allopatric Speciation;   for instance rivers can cause a division among species. The loss of biodiversity is causing harm to our environment.
