GEO 702 Lecture Notes - Lecture 1: Eugenius Warming, Water Cycle, Hypothermia
• Effect Of Technology On Environment:
• Today's Human Nature:
• In today's world, humans are in a very relaxed cycle they eat, they watch television, they
sleep
• Most people do not realize the health risks they are taking everyday when they do their
daily tasks
• Humans are more reliant on machines to do simple activities
• Such as changing the channel or travelling
• Nowadays humans live a convenient and relaxed life ex: change channel using remote
instead of having to get up and go up to the TV to change the channel as there were no
remotes in the past
• Fresh food had to be cooked, it couldn't be refrigerated or frozen but on the other hand
people were healthier previously as compared to humans nowadays -there's heart strokes
due to fatty foods and other diseases due to the food we eat
• Technology Makes Life Easier:
• Technology does make activities uncomplicated and genuinely makes life easier. But
people are at great risk to their health with the advancements in technology
• The air in cities is so full of smoke - This leads to poor air quality
• Technology also makes activities uncomplicated hence makes life easier for us ex: we can
fly from city to city instead of having to rely on animal transport. E-mails instead or letters
• Not only do humans create entertainment and ease of life but they also make pollutants
and contaminants - creating ease of life creates a lot of pollution
• Life due to technology is sedentary - kids don't play outside anymore, obesity is rising
• Pesticides: a pest is an organism (insect, mice that cause damage) cide: kill so Pest and
Cide: so killing the pest so if that pest is insect we call it insecticide. For mouse/mice
(rodents) we call it rodenticide. For bacteria bactericide. For fungus fungicide - cide
means killing - so killing these organisms/bacteria's
• In the video: pesticides were used to ensure that crops are healthy and not damaged.
These pesticides were used to ensure that rodents, insects, bacteria don't damage the
crops and we have healthy crops but these pesticides are chemicals and they are
accumulated in the tissue of the crops and if they are consumed by humans then after
years a disease could emerge ex. Cancer in a person but if the pesticides weren't used and
the whole world got organic food then there wouldn't be enough crops and there
wouldn’t be enough food - but if this it is controlled then we may have less influence of
technology on our health and the env
• The Air We Breathe And The Water We Drink:
• Not only have individuals fabricated new ways of entertainment, but have built factories
which pollute the air they breathe and water they drink

Document Summary
Effect of technology on environment, today"s human nature: E-mails instead or letters: not only do humans create entertainment and ease of life but they also make pollutants and contaminants - creating ease of life creates a lot of pollution. Life due to technology is sedentary - kids don"t play outside anymore, obesity is rising: pesticides: a pest is an organism (insect, mice that cause damage) cide: kill so pest and. Cide: so killing the pest so if that pest is insect we call it insecticide. For fungus fungicide - cide means killing - so killing these organisms/bacteria"s. In the video: pesticides were used to ensure that crops are healthy and not damaged. We need to stop the pollution of water resources because wastewater volume is larger than what it used to be. On the other hand, the water from rivers and lakes needs to be treated to ensure that it is drinkable and safe to use.
