The first anti-dam movement in the North was launched to save which river?

Franklin River

The correct answer is option (3) - Franklin River

In every country where a mega-dam is being built, one is likely to find an environmental movement opposing it. Increasingly anti-dam movements are pro-river movements for more sustainable and equitable management of river systems and valleys. The early 1980s saw the first anti-dam movement launched in the North, namely, the campaign to save the Franklin River and its surrounding forests in Australia. This was a wilderness and forest campaign as well as an anti-dam campaign.
