(6.03 MC)A mining company wants to extract methane hydrates from the seafloor. Which two factors would a marine biologist most likely investigate to determine if this is appropriate?

If the area is ecologically sensitive and how the activity would impact the food web
The size of the methane deposits and how the activity would impact the water temperature
The amount of drilling needed and how the activity would impact the pH of the water
The potential energy of the methane deposits and how the activity would impact the deep sea currents

(6.03 HC)The activities that take place to meet human needs can often be harmful to ecosystems. By developing sustainable practices, however, we can help protect our environment. Which of the following changes would be most helpful in reaching sustainability?

Building more water treatment facilities
Fishery officials setting total allowable catch limits for fish
Mining the seafloor to remove valuable energy resources
Using natural gas for fuel instead of burning petroleum
