SAN ANTONIO (KTSA News) – President Trump is coming to Texas on Thursday to talk about the need for a wall along the U.S/Mexico border.

Joining the ranks of those opposing the structure, is the Sierra Club.

They feel the wall will be a failure as an immigration policy and cause irreparable damage to the environment.

The Sierra Clubs Sergio Avila talked to us about the negative environmental impact the wall will have on border communities.

“It starts with the construction. There could be bulldozers. There could be tractors. There could be semi-trucks. The materials. All of that could have an impact on wildlife.”

Avila says the Sierra Club is urging Lawmakers to vote against any funding for the border wall.

“Billions of tax payer dollars will be spent to cause damage to The National Butterfly Center, several state and national parks, and other public lands.”

The Club will have some members in McAllen when President Trump visits the border community on Thursday.
