Roughly 8,000 people filled a northeast Nebraska farm Saturday to hear Willie Nelson and Neil Young perform at a concert organized by opponents of the proposed Keystone XL pipeline.
The Lincoln Journal Star reports politicians and activists spoke to the crowd on Art and Helen Tanderup's farm about the pipeline project between performances.
Young said before the concert that he thinks it's important for America to use more renewable energy, and he supports people who are trying to offer solutions.
The proposed TransCanada Keystone XL pipeline would carry oil from Canada south to the Gulf Coast.
Pipeline critics worry it could contribute to pollution and contaminate groundwater.
TransCanada says the pipeline would have advanced safety features. The southern leg of the pipeline between Oklahoma and Texas is already operational.
