Re "Mars test-drive goes smoothly," Aug. 23 The focus on this ridiculous adventure to Mars while our planet is circling the drain is the height of insanity. Instead of focusing our resources in a last-ditch effort to save our Earth, we are embarked on a fantasy voyage. Maybe the reality of our situation is so awful that our last grasp on our sanity is avoidance. Russell Blinick Encino ALSO: Letters: Exam kudos for L.A.

New trailers out this week for two 2013 science fiction epics, "After Earth" and "Oblivion," feature different stars (Will Smith and Tom Cruise, respectively) who have one thing in common: a dire prediction for the future of humanity on our dear planet Earth. "After Earth" is the new film from M. Night Shyamalan, who has stepped away from directing his own original scripts with this project, which is credited to writers Stephen Gaghan and Gary Whitta. It stars Smith as a spacefaring general and his son Jaden Smith playing the general's son, on patrol over the planet Earth 1,000 years after a cataclysmic event that left the planet uninhabited by people.

Re "Women greener than men?," Opinion, June 13 Women historically have been the nurturers, the caregivers. Of course they would have greater sensitivity to the environment's effect on humans. Will the caveman macho mentality of most men (and many women) finally mature into responsible stewardship of the Earth? My guess is not until the damage humans have done smacks us more directly in the face. That's a sorry legacy to leave to our next generations.

Re "The Israel factor in November," Opinion, Aug. 12 Dan Schnur ignores the centrality of President Obama's environmental policies to Israel's survival. By advancing alternatives to oil such as wind and other renewables, Obama guts the financial base of Israel's enemies. While Mitt Romney would keep us dependent on fossil fuels, the president is committed to Israel's - and our - energy security. Peter L.

If you've ever felt the earth shudder beneath your feet during an earthquake, you're no stranger to the effects of Earth's ever-roaming tectonic plates. While scientists have linked the movements of these rigid, puzzle-piece slabs to our planet's most violent events -- quakes, tsunamis, volcanic eruptions -- they have struggled to explain exactly how they came to exist in the first place. Now, in the journal Nature , two geophysicists have proposed that Earth's outermost layer, or lithosphere, was microscopically weakened and brittled by movement in viscous layers below it billions of years ago. Study authors David Bercovici of Yale University and Yanick Ricard of the Univeristy of Lyon note that Earth is the only planet in the solar system that appears to have tectonic plates that move freely on its surface, propelled by the motion of layers below.
