I chose to compare: Malaysia and Australia


Males per 100 Females: 102.6

People per sq. km: 98.1

Children per woman: 2.5

Current population: 32.2 Million

Estimated population 2050: 42.9 Million



Males per 100 Females: 98.8

People per sq. km: 3.3

Children per woman: 1.7

Current population: 25.1 Million

Estimated population 2050: 32.5 Million


Malaysia's population pyramid has the highest numbers in the children ages from 0-14 years old before steadily declining. It's around the ages of 50 and up that the numbers begin to shrink which seems pretty normal in my opinion as this means a high birth and mortality rate for the youth but as people get older things like accidents, illness and more are affecting young adults and the elderly people.

Australia's population pyramid differs from Malaysia as their numbers peak at the population age of 25 before fluctuating and decreasing numbers as the population gets older. Between the ages of 0-15 years old being compared to Malaysia's pyramid are much smaller which has me believe that their could be lower birthrates or virus/diseases that may be hitting the youth much harder impacting that age group population numbers.

The overall population prediction for 2050 is a fairly big gap for Malaysia and Australia as Malaysia's population is predicted to grow around 10 million more in 2050 while Australia is predicted of a growth of 7 million difference by 2050. This is to be expected as Malaysia has higher numbers in the birthrates while Australia has greater numbers in their middle age group.

To avoid talking about a certain pandemic that is all over the news around the world right now, I have found an article related to the Amazon River and how it might disappear in the upcoming future.

Article Link:

In the article, "Distant Source of Amazon Is Evaporating Away", published Oct. 4, 2019, the glaciers that cover the Mismi which is a 18,465 foot mountain are melting away. These glaciers within the Andes mountain ranges are an important water source for Peru's inhabitants and even more important for Peru's subsistence farmers that reside in remote mountain communities. According to a glaciologist, Lumzmila Davila,

"...Peru has now lost just over 53% of its original glacier cover, or 1,285 square kilometers of the original 2,399 square kilometers, since 1962, a period roughly equivalent to when industrial greenhouse gas emissions first began ramping up."

The cause to blame for the glaciers melting are being pointed towards the burning of fossil fuels from industries but more interestingly partial blame is being put on sheep and cattle which are being raised in the high plain communities by farmers. An certain breed of cattle is being blamed for harming the ecosystem within the high plains of Peru, as unlike the native farm animals of llamas, alpacas, and vicuña, the hooves of these cattle are damaging the soil which in turn is making it difficult for the plant life to regrow. The method of how the foreign cow eats is also to blame as it is known for ripping the roots from the grass unlike the South American camelid species which are only chewing the tips of the grass.

As the glaciers are expected to evaporate away within a year, the people of South America are seeing this as a bad omen for the future.

I have decided to scrap my old post for a topic better suited for the subject at hand. With that being said I found another article: “Melting glaciers in the Russian Arctic reveal five new islands'.

The Russian Navy had discovered islands back in 2016 through the use of satellite imagery and the size of the islands according to the article:

“They range in area from 900 to 54,500 square meters (about 9,690 to 586,630 square feet) -- as big as 10 football fields.'

As for the precise location of these islands, they can be found near the coast of Novaya Zemlya and close to the Vylki Glacier. Russian Navy researchers have been using satellite data in order to map out and study the changes in the Novaya Zemlya coastlines and Franz Josef land. Between 2015-2018, around 30 more islands had been discovered off of these coastlines and bay areas. A similar topic happened over in the glaciers of Canada when land that had been buried for over 40,000 underneath the Arctic snow and ice.

My personal views of the topic are a mix of fascination and ironic twist. While global warming is expected to take land away due to flooding, we are instead discovering hidden lands within glaciers.

Greetings everyone,

My name is Vincent Guerena and I am currently taking this geography class for my teaching degree. I have studied geology in the past, and I will say that it is not my expertise. A bit about myself: I do love animals, I currently own two cats, and I am currently trying to get into the betta fish hobby. Aside from animals I am a cartoon artist in the works, old Warner Bros. cartoons (such as Loony Tunes and Animaniacs) have always inspired me to draw, so my art style shares similarities as those cartoons were my references. I do have dreams of becoming an animator, but that is something I plan to carry out on my spare time.

For my three map locations, my birthplace was in Mount Elizabeth Hospital in Singapore as my dad was in the air force so we traveled around frequently. I am currently living in Anchorage Alaska and recently moved to the small neighborhood of Marsha Loop. The place I wish to visit is Tokyo Japan, for a few years I grew up just on the outskirts of Tokyo where a U.S. Military base was. I wish to revisit Japan just for memory sake.

Thank you all for taking the time to read my post, I wish a wonderful semester for everyone!
