Liberal issues

The MSM seems to treat all environmental concerns as liberal concerns.
Don't conservatives love their kids? I think they do. So how can they justify labeling environmental laws as liberal? Liberal is now a term present day conservatives (PDC) have hijacked to mean anything they don't like.
Can they be so blind that they can think "My kids will be safe because (fill in the blank (eg Global warming)) is a liberal concept"?

My take is that the PDC is so intent on supporting business they forget that they and their families are also vulnerable to the damage we are doing to the ecosystem. Being rich won't save them. Or us.
