PLEASE HELP ! Explain one example of how the U.S. has struggled to balance energy independence and environmental protection.

The US's main source of energy since 1932 was always wind energy but this all changed when it was discovered that the windmills making this energy was killing off many species of birds. The long beaked eagle was one of the many birds that went extinct in this time period. Because the long beaked eagle was the only natural predator to alligators, alligators began to overpopulate many parts of the southern US. They started to look for more food sources like farms and would sometimes even wander into cities and eat people! In 1976 the anti-windmill act was passed and the US has been using hydro power as there main source of energy. The US has also adapted eco-friendly wind turbines that serve as nests for birds and provide very little energy.

Explanation:

Percolation in soil is simply the movement of the water through the soil and a soil percolation test is the means to measuring this movement.

Through this process lakes of underground water is filled up.
