### Ya sake shiga kuma ya yi murabus daga kwamitin
Eventually reconciled with the Sierra Club, Brower was elected to the board of directors for a term from 1983 to 1988, and again from 1995 to 2000.  Brower was deeply concerned about issues of overpopulation and immigration – one of many issues that led to his resignation in protest from the board of directors in 2000. "Overpopulation is perhaps the biggest problem facing us," he said, "and immigration is part of that problem. It has to be addressed." His favorite example of how immigration should be addressed was the work of his cousin Boone Hallberg, a botanist who immigrated to Oaxaca to build a more sustainable agricultural economy in the area that so many of the workers on his family's California farm had been forced to leave.&#x5B;**&#x5D;

## Ya kafa Abokai na Duniya

### Yunkurin kamfen na muhalli
Although Brower's background was in the wilderness preservation wing of the conservation movement, he quickly led FOE to take on many of the issues raised by the new environmentalists.  FOE campaigned against the Alaska pipeline, the supersonic transport airplane (SST), nuclear power, and the use of the defoliant Agent Orange in the Vietnam War.  After Ronald Reagan was elected President in 1980, FOE led the opposition to Interior secretary James G. Watt's efforts to sell and lease public lands in the West and develop land adjacent to the National Parks.

### Ya yi murabus daga jirgin
Brower ya yi ritaya a matsayin babban darektan FOE a ranar cika shekaru goma a 1979, amma ya ci gaba a matsayin shugaban kwamitin daraktocinsa.
