Day of the Animals (1977)

The depletion of the ozone layer around Earth is starting to piss off the animal kingdom. In higher altitudes, the critters have decided to unleash their wrath upon a group of nature-loving hikers including Christopher George, Lynda Day George and Leslie Nielsen. Director William Girdler followed up his 1976 film GRIZZLY with this eco-horror, nature-runs-amuck-flick. Includes original trailer.
