What we really hear

It is amazing to think about how keen organisms' sensation and perception of audio is in the grand scheme of evolution. The humans' ability to recognize distinctive sounds and piece together complex language into thoughts is so advanced yet normal that we overlook how complicated it really is every single day. Kendra Cherry discusses the science of how the ears work in her article (1). So I asked myself that there has to be more complications to the way that the most intelligent species known can communicate so easily. At source (2) it lists different ways that the audio perception can be muffled by such as auditory discrimination, auditory foreground-background differentiation, auditory blending, and auditory sequencing. The failure of auditory discrimination involves people failing to find discriminations between different sounds. This difficulty to comprehend differences in language would prove to be increasingly difficult for children trying to advance through schooling. Then there are the auditory differentiations that help us differentiate from the unnecessary pieces so our brain does not get overwhelmed by the unimportant. All of these auditory tools can hurt or help us but we must learn to accept them and try not to mess with them or a persons' abilities.

Population Crisis!

According to the United Nations, "The world's population is expected to increase 2.5 billion people in the next 43 years" and "Most of the growth is concentrated in the 60-plus age grouping". This may not be too shocking to most considering how far medicine and health has improved in our society. However great these advancements have been for humankind, I have concerns about the longevity of our ever increasing population. I believe that the earth has natural capacity and certain ecosystems should not be pushed over their limits. The Earth recently reached the amazing feat of supporting 7 billion people on the planet, but I believe that this is simply setting us up for disasters in the future. For example, if the Midwest gets a drought thousands will instantly go hungry or even parish. It's a sad situation to think about but scary none the less. Additionally, Americans lead a lifestyle that is rivaled by no other cultures that features wasting products and overusing. To think if other parts of the world consumed at the rates of Americans the natural capacity would be much smaller. This situation is new to the Earth, so it will be interesting to see how our population reacts to the crisis that will be upon us shortly
