Environmental Issues Due To Human Flashcards
Why is deforestation bad
Desertification - woodland clear + burn. Cause soil erosion - seed can’t grow = succession less likely
Decrease biodiversity
Global warming - co2
Conservation method for deforestation
Coppicing- can only cut wood in different area at different season (trees can grow back)
Leave stump for regrowth
Why is over finishing bad
Less biodiversity
Food chain disrupted
Conservation for over fishing
Fishing quota- limit amount of fish one can catch
Restrict fish net or mesh size - can’t go over or under a certain amount, juvenile won’t be caught
No fishing during breeding season - time to grow
Why is fish farming (aquaculture) bad
Disease + pest spread easily
-if use medication = immunity
Farm fish can leave - genetically modify to grow fast and bigger
-infraspecific competition: out compete own kind for mates + food
-decrease biodiversity: hunt better - eat more to sustain
-offspring: offspring similar in competitiveness - farm fish becomes the norm for that specie
Importance of environmental monitoring
-check for:
pH, biodiversity, chemical, microbes in area
To make industrialisation less harmful for environment + human
