New Material

  • What is the negative impact of building a dam for hydroelectric power?

  • Prevents water from carrying nutrients down stream. Also, re-directs water at the cost of the ecosystem

  • Why was Hurricane Katrina so devastating?

  • Below water already, once Levees were breached the water went to the path of least resistance. Difficult to get rid of the water.

  • Benthic zone – bottom of the pond / lake. Feels silty from decomposing leaves, sticks,… high nutrient, but low O2
