The activities that take place to meet human needs can often be harmful to ecosystems. by developing sustainable practices, however, we can protect our environment. which of the following changes would be most in reaching sustainability? a) building more water treatment facilities b) releasing aquaculture-raised fish into the natural environment c) mining the seafloor to remove valuable energy resources d) using natural gas for fuel instead of burning petroleum

The answer is DEFINITELY NOT building more water treatment facilities or using natural gas for fuel instead of burning petroleum. I would know because i took the test and these are not correct.

Explanation:

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
