Actually all the major environmenetal laws (aka "ACTS") had tremendous bipartisan support. Some of the most broad ranging and forward thinking laws were signed into law by conservative Presidents.
Nixon signed the National Environmental Policy Act into law, as well as, the Environmental Protection Agency, NOAA, The Clean Air Act (CAA), The Clean Water Act (CWA) and the Endangered Species Act.
Ford signed the Safe Drinking Water Act (SDWA) into law, as well as the Resource Conservation and Recovery Act (RCRA) and the Toxic Substance Control Act (TSCA).
Jimmy Carter signed into law revisions strengthening both the CWA and CAA (including title 5) and he signed the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) into law.
Reagan's record is mixed. He did sign the Environmental Protection and Community Right To Know Act (EPCRA) and the Superfund Reauthorization Act (SARA) into law but he also reduced EPA's enforcement ability drastically.
George H.W. Bush signed the Clean Air Act Amendments into law and hired the first professional environmentalist to head the EPA and restored much of the funding that undercut EPA's enforcement capabilities.
By this time the vast majority of the environmental laws and regulatory framework in this nation, that we take for granted now, were in place and functioning. The main argument currently isn't over their validity because of extraordinary results they achieved but over the scope of the regulations and enforcement.
Anyway you put it we've come a long, long way since 1970.

A lot of bible thumpers I have run across do not actually believe radiometric dating techniques, dismiss any notion of an ancient Earth, and they go through all manner of mental contortions to explain the vagaries of the fossil record.
Siberian Traps likely culprit for end-Permian extinction
Around 252 million years ago, life on Earth collapsed in spectacular and unprecedented fashion, as more than 96 percent of marine species and 70 percent of land species disappeared in a geological instant. The so-called end-Permian mass extinction *— or more commonly, the “Great Dying” — remains the most severe extinction event in Earth’s history.
Scientists suspect that massive volcanic activity, in a large igneous province called the Siberian Traps, may have had a role in the global die-off, raising air and sea temperatures and releasing toxic amounts of greenhouse gases into the atmosphere over a very short period of time. However, it’s unclear whether magmatism was the main culprit, or simply an accessory to the mass extinction.

Some of the most wondrous creatures in the history of our planet roamed on land and thrived at sea during the Permian period. Among them were the first saber-toothed carnivore and a 40-foot shark with a circular saw for a mouth. But something terrible happened 252 million years ago, when our world suffered the worst of five major mass extinctions. Just recently, scientists think they have finally identified the smoking gun that nearly wiped out all life on Earth.

Thanks Ken. Man, I am a geek for this kind of stuff.
One thing I like about the Permian era - ginormous bugs!
Reign of the Giant Insects - Permian Period
Giant insects ruled the prehistoric skies during periods when Earth's atmosphere was rich in oxygen.
Insects reached their biggest sizes about 300 million years ago during the late Carboniferous and early Permian periods. This was the reign of the predatory griffinflies, giant dragonfly-like insects with wingspans of up to 28 inches (70 centimeters). The leading theory attributes their large size to high oxygen concentrations in the atmosphere (over 30 percent, compared to 21 percent today), which allowed giant insects to get enough oxygen through the tiny breathing tubes that insects use instead of lungs.

It might be UV radiation that drove the catastrophic extinction event, because the volcanic gasses from the Siberian traps eruption destroyed the atmospheric ozone layer.
