Activity 3.1 – Human Population

Image
     For my more developed country, I chose Canada and for my less developed country, I chose Afghanistan. Looking at the two demographic profiles side by side, it is clear that one country is much more developed than the othe r. If you are using only common knowledge of these two countries , it is not difficult to come to this conclusion, but with the demographic profiles, we can get a better understanding of why this is, and we can compare them to the world demographic profile. This data will be able to show us which country is closer to the world’s statistics and what that m eans.   Starting at the birth rate per 1,000, we can see that Afghanistan's birth rate of 32 and fertility rate of 4.3 is significantly higher than Canada’s 10 birth rate and 1.5 fertility rate . In less developed countries this tends to be the case. Afghanistan and Canada have both experienced a decrease in fertility rates since 1990 (Population Reference Bureau, 2021) but are proje...

Activity 2.3 – Biosphere and Interconnections

Image
In this concept map, I explored biodiversity. Three main factors contribute to whether or not an ecosystem has biodiversity. First, is genetic variation which is the DNA that makes up an organism. Then, there is species richness is the number of different kinds of species in an environment. Lastly, there is the variety and dynamics of ecological communities on larger scales. This is the abundance and the interaction of species in large biomes.     Biodiversity is the variety of species and their interaction with their environment. There are three main contributors to whether an ecosystem is biodiverse. First is genetic variation.  Genetic Variation is composed of the DNA of an organism. This DNA is what gives an organism its unique attributes. Every organism has a spec ial DNA sequence of its own. As an environment changes, the species ’ DNA will change as they form mutations to adapt to their environment . Having genetic variation is a very desirable attribute of...

Activity 2.2 – Cyrosphere: Muir Glacier

Muir Glacier from 1880 to 2019 ( G.D. Hazard, 1880) (USGS, 2011) (Google Earth, 2019) This is the Muir Glacier in Alaska. It is a part of Glacier Bay National Park. This park used to have about 80 glaciers a long time ago, but now only 26 remain, including Muir. Muir Glacier was first explored in 1879 by John Muir who it was named after. Since its discovery, it has retreated about 60 miles and is nearly completely gone. This glacier used to thrive all throughout Alaska's waters, but it now has receded far back onto the land. It will continue to retreat and is expected to be gone by 2030 along with the rest of Glacier Bay National Park's glaciers.  Problem:       Glaciers are melting at a n alarming and rapid rate. This is affecting both human life and animal life drastically. Our glaciers are vital to keeping our planet healthy. They have a high albedo, so they keep the earth’s temperature cool. They also act as freshwater reservoirs as they store water in the ...
