Earths Population Changes

For our 3 unit of Population class, we learned a lot about the population of our picked organisms over a ten year time period. We went over our symbiotic relationship of our organism compared to humans and, other organism. Then we learned about the steps that you categorize them in boxes. For example a bird and an alligator this is an example of mutualism. For my project I choose to do the grey wolf and I learned that they are very important to the environment. With there numbers steadily increasing they are surely showing signs of rebirth. This is an important job because without them, we see would see how other species would be affected. During your course of unit 3, we also learned about statistics, arithmetic and geometric sequences. We later had to apply this in are 10 year model for both humans and, the grey wolf. Anyway here is my presentation. 

Humans relationship with Grey Wolfs 

Humans are affecting the grey wolves population by their habitat being destroyed at a rapid pace. People are continuing to want more and more land to place their homes on or their farms/ranches. Businesses also continue to tear down the areas that these animals inhabit. Without a vast habitat for them to live in, they struggle to find enough food for survival. Their habitat has been on a constant change ever since humans populated in their areas. Overall causing a drastic decrease in the grey wolves population. Most wolves were either hunted by humans or killed for sport. There symbiotic relationship would be a competition because humans are taking over the grey wolves habitat and one is benefiting and the other is depleting in numbers.

Grey Wolves Population /Human Population

Year	Grey Wolf Population	Human Population
1990	1,306	5.29 billion
1991	1,340	5.38  billion
1992	1,397	5.43  billion
1993	1,463	5.46 billion
1994	1,533	5.63  billion
1995	1,647	5.71  billion
1996	1,810	5.80  billion
1997	2,023	5.88  billion
1998	2,762	5.96  billion
1999	2,388	6.04  billion

Although the time period in this graph does not portray a decrease in total of the grey wolves population. About 1 decade before this the numbers were way lower, but since they were almost extinct humans chose to create areas, and sanctuaries for them to obtain a steady pace in reproducing offspring and increasing population over time. On the other hand the human population is increasing rather faster and is more consistent along the years compared to the grey wolves population.

Graph comparing the two populations

Humans population would be a Geometric sequence because there's a dramatic change in population as it increase by 1.28 percent approximately by each year. This would be represented as

G= 5.29  and R= 1.28

The grey wolves population is although technically a sequence but it isn't an arthritic or a geometric sequence. There's isn't any numerical repetition of order and isn't continuous.

Hello and welcome to my video about how human population growth affects other populations.
In this video we will be discussing facts, data and how humans have a symbiotic relationship with grey wolfs.

The scientific name for the grey wolf is Canis lupus it first appeared about a million years ago in Eurasia and later migrated to North America.

The grey wolf lives in the dense forest of the Northern Hemisphere and ranges to Europe, Asia, Africa and Antarctica. The grey wolf has evolved to have a thick coat of fur. This for them provides warmth for them. Over the years their habitat has been on a constant change ever since humans populated in their areas. Overall causing a decrease in the grey wolves population. Most wolves were either hunted by humans or killed for sport.

Humans and grey wolves have a symbiotic relationship with each other that would be a competition because humans are taking over the grey wolves habitat and one is benefiting and the other is depleting in numbers.

From my research I have found that grey wolves can run up to speeds of 31 – 37 mph. Their average lifespan is from 3-5 years, and they have a very incredible sense in smell. The Grey wolf's long nose holds the key to its abundance of smell. They have a sense of smell that is about 100 times greater than humans and they use this sense while hunting. Grey wolves are also social animals that live in packs up to 7-8 wolves. Which means they need to communicate by howling in different tones and, pitches to get there message through to each other from long distances.

Now let's talk about humans!

Humans tend to live on average up to 79-81 years. Humans reproduce at a rapid pace.. On average there are 353,000 babies born each day around the world. Overall this increase in our population ultimately depletes other species growth rate and that is what leads to extinct animals.

Later on in this project made two graphs that show the population growth for both grey wolves and humans.

Here is my graph.

In both of my graphs they portray an increase in numbers for both populations over a ten year period.

And that's about it , Thank you for watching and have a great day.
