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.

ww1 weapons: tank. tanks were used for the first time in the first world war at the battle of the somme. they were developed to cope with the conditions on the western front. the first tank was called 'little willie' and needed a crew of 3.

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
