Explanation:
A major problem with using 15 years of data to predict 100 years of data is that the 15 years could have been setting a trend, then level off.
For example, if the 15 years of data was a graph, and it was going up every year, then what if 20 years into the 100 years it stops going up? Then that means the data was invalid because there wasn't enough to base any trends off of.
You can prevent this from happening by extending the collection time of data and to reduce the amount of time that the data will be used to predict.

Hey there! I'm happy to help!
One thing that the Balkan Mountains have done is create very distinct cultures. Every location has different cultures, but these mountains are very large physical barriers to cultural interaction, so this has led to a plethora of different ethnic and cultural groups in the Balkan region.
Another thing that they have done is create a sort of hierarchy where those that are more well off live in the valley, further away and from the mountains, and those who may not be as well off, considered inferior, or simply desire to practice transhumance, herding, or being a nomad will be dwelling in the mountains. It creates different "zones" based on the geography of the area.
A final thing these mountains have done is create cultural tension in the Balkan Peninsula. Since so many of these groups develop isolated from from other cultures, efforts to unite these groups usually fail and it leads to rancor between these distinct groups. This is why this area has been very war-torn before in states such as Bosnia and Herzegovina.
Have a wonderful day and keep on learning! :D
Explanation:
Animal indicator list is a barometer to check how a particular ecosystem is affecting the lives of particular animals. The indicator measures stress or behavior in the ecosystem to know whether to protect the specie or allow them undisturbed
This is to avoid or reduce to barest minimum incidences of extinction of such specie in the ecosystem.
The grizzly sudden reduction in number from well over 100,000 in California to less than nothing in 1942 triggered the need to protect the grizzlies from human destruction and possible extinction. Grizzlies was a national specie and appeared in the flag of California. The population gradually reduced in most of the states of Idaho, Utah, Alaska and many more.
The grizzlies in 1975 were declared protected species to avoid being hunted or trapped by humans and to repopulate them in the areas where they once lived. Their future will depend largely on humans ability to allow them to coexist with them, by setting out a large area for them to live and regroup.
This will go to balance the ecosystem which has been tampered or disturbed by development.
