>>> ANYTHING, IT IS TUESDAY, APRIL 12.

THANKS FOR JOINING US.

FOR THE SEVENTH TIME THIS YEAR AN INMATE HAS DIED WHILE IN CUSTODY AT THE SAN DIEGO COUNTY SHERIFF'S DEPARTMENT.

THE AGENCY HAS BEEN UNDER SCRUTINY SINCE THE TATE AUDIT FOUND THAT AT THEIR GEL RANK AMONG THE HIGHEST IN THE STATE.

OUR REPORTER HAS MORE ON THE CALL FOR CHANGE.

>> Reporter: CIVIL RIGHTS LEADERS MET WITH INTERN SHERIFF ANTHONY RATE THIS WE NEED TO TALK ABOUT THE HIGH NUMBER OF IN CUSTODY DEATHS.

THE MEETING WAS PLANNED EVEN BEFORE THE LATEST DEATH ON MONDAY.

>> GOING TO JAIL SHOULD NOT BE A DEATH SENTENCE AND THAT IS WHAT I TOLD THE SHERIFF AND THAT IS WHAT YOU ASKED THE SHERIFF TO THINK ABOUT WHEN HE GOES HOME AT NIGHT.

>> HE IS THE PRESIDENT OF THE PEOPLE'S ASSOCIATION ADVOCACY.

HE ASKED THE SHERIFF TO ENDORSE THE SAVING LIVES IN CUSTODY ACT.

IT WILL MAKE THE DEPARTMENT A PLACE THAT RECOMMENDATIONS MADE BY STATE AUDIT THAT FOUND THE DEPARTMENT HAD AMONG THE HIGHEST DEATH RATES DUVAL COUNTY GELS AND IT FELT TO PREVENT AND ADDRESS THE DEATH.

>> THE FACT WE HAD A SEVENTH DEATH IN THE COUNTY JAIL YESTERDAY DEMONSTRATES THE URGENT NEED NOW.

>> WE NEED TO SEE A VERY EXPEDIENT WAY OF GETTING ANSWERS TO FAMILIES.

>> Reporter: AN INDEPENDENT REPORT BY THE CITIZENS OVERVIEW ALLOW ROOM FOR YOU LORD RELEASED ON FRIDAY SHOWS THAT SAN DIEGO COUNTY JAILS HAS THE HIGHEST NUMBER OF EXCESS DEATHS IN PEOPLE WHO DIED WITHOUT BEING SENTENCE.

>> IT IS SUCH A CONCERN THAT I THINK AREAS OF ADDITIONAL RESEARCH SHOULD BE DONE.

>> Reporter: PAUL PARKER IS THE PRESIDENT OF THAT OVERSIGHT GROUP.

HE HAS PROPOSED TO ALLOW INDEPENDENT JURISDICTION OVER THOSE PROVIDING MEDICAL AND MENTAL HEALTH CARE IN THE JAILS .

>> RIGHT THERE AND THEN, IF WE CAN HAVE THAT, WE CAN GET THE WHOLE PICTURE AND BE ABLE TO BETTER RECOMMEND CHANGES.

>> Reporter: THIS ISSUE SHOULD MATTER TO EVERYONE.

>> MANY OF THESE FOLKS ARE EITHER EXPERIENCING HOMELESSNESS OR MENTAL HEALTH ISSUES OR ADDICTION ISSUES.

THESE ARE THE ISSUES THAT NEED TO BE ADJUSTED RIGHT NOW.

>> Reporter: THEY WILL DISCUSS THE FINDINGS OF THE REPORT TONIGHT.

HE EXPECTS THE SHERIFF TO BACK THE BILL BEFORE IT GOES INTO COMMITTEE.

WE REACHED OUT TO THE SHERIFF'S DEPARTMENT FOR COMMENT AND THEY DECLINED.

>>> A UKRAINIAN MILITARY OFFICIAL SAYS AS MANY AS 22,000 PEOPLE MAY HAVE BEEN KILLED IN MARIUPOL.

THAT IS THE LATEST ISSUE AS IT IS UNDER SIEGE BY RUSSIAN FORCES.

>> Reporter: AS RUSSIA TAKES MOVE THROUGH MARIUPOL, SMOKE ABOVE THE RUINS, AND OFFICIAL NOW SAYS OF TWO 22,000 PEOPLE MAY HAVE DIED IN THE CITY.

THOSE WHO SURVIVED DESCRIBE THEIR HOMES TURNED INTO DESTRUCTION.

>> THERE WERE DEAD BODIES IN THE STREETS.

>> YOU'VE SEEN THE DEVASTATION THAT RUSSIAN AIRSTRIKES HAVE WROUGHT ON THE CITY BUT OUR ASSESSMENT IS UKRAINIANS ARE STILL FIGHTING FOR IT.

>> Reporter: AMERICAN AND UKRAINIAN OFFICIALS HAVE NOT CONFIRMED REPORTS OF A POSSIBLE CHEMICAL ATTACK ON AMERICA.

PUTIN SAID TODAY THAT PEACE TALKS WITH UKRAINE ARE NOW AT, QUOTE, GET IN.

>> THE OBJECTIVES ARE CLEAR AND NOBLE.

I SAID THAT AT THE BEGINNING.

IN MY VERY FIRST SPEECH IN MY ADDRESS TO THE NATION IN THE ARMY I STATED THOSE OBJECTIVES.

>> Reporter: THOSE ARE NOW NEARER TO FOCUS ON THE DONBAS REGION.

>> IT IS LIKE WALKING A TIGHT ROPE.

IF YOU STOP THINKING, YOU LOSE TIME AND BALANCE.

TO HOLD ON, YOU JUST MUST GO AHEAD AND DO WHAT YOU DO.

>> Reporter: KPBS NEWS.

>>> IT IS CONTRIBUTING TO INFLATION IN THE UNITED STATES.

IT HITS A HEIGHT NOT SEEN SINCE THE REAGAN ADMINISTRATION.

ACCORDING TO THE LATEST DATA FROM THE BUREAU OF STATISTICS, THE CREASE WAS A .5% FOR THE YEAR THAT ENDED LAST MONTH.

THAT OUTPACES THE 7.9% REPORTED IN FEBRUARY AND IT IS A PEEK NOT REACHED SINCE DECEMBER 1981.

SAN DIEGO COUNTY'S INFLATION RATE WAS BELOW THE NATIONAL AVERAGE IN MARCH AT 7.9%.

>>> WHILE STILL HIGH, GAS PRICES ARE SLOWLY DROPPING.

THE COUNTYWIDE AVERAGE PRICE FOR A GALLON OF REGULAR GAS FELL BY ABOUT A PENNY TODAY.

IT WAS $5.81.

THE AVERAGE HAS DROPPED AROUND $.20 IN THE PAST TWO WEEKS.

AAA SAYS THERE IS PLENTY OF ROOM FOR PRICES TO DECREASE FURTHER.

>>> MORE THOUGHTS ABOUT THE CITY COUNCIL APPROVING NEW CONSTRUCTION.

THERE IS SOME SKEPTICISM ABOUT THE PLAN.

>> Reporter: ACCESSORY UNITS GO BY A LOT OF DIFFERENT NAMES, OR JUST BACKYARD UNITS.

WHATEVER YOU CALL THEM, THE CITY COUNCIL HAS APPROVED A NEW AMENDMENT TO GET MORE OF THEM BUILT FOR LOW INCOME HOUSING BY PROVIDING INCENTIVES TO THEIR OWNERS.

A REAL ESTATE BROKER IN DEVELOPER AGREES.

>> RIGHT NOW THE AVERAGE TIMELINE TO BUILD A MULTI-FAMILY STRUCTURE TAKES 3 TO 4 YEARS.

THAT IS A REALLY LONG TIMELINE.

>> Reporter: THEY CAN BE BUILT IN HALF THE TIME.

SAN DIEGO LANDOWNERS CAN ALSO BUILD A BONUS GRANNY FLAT THE CAN BE RENTED AT MARKET RATES.

IT HAS TO BE RENTED AT A REDUCED RATE TO MODERATE INCOME RESIDENTS FOR 15 YEARS OR RENTED FOUR 10 YEARS.

IT IS A WAY TO ADDRESS THE AFFORDABILITY ISSUES IN THE REGION.

>> WE MAY NOT SEE FAMILIES OF FOUR OR FIVE MOVE IN BUT WE ARE RELIEVING SOME OF THE COMPETITIVE PRESSURE THAT THOSE FAMILIES WERE FILLING BY NOT HAVING THESE OTHER HOMES, THESE NEW HOMES COME ON THE MARKET.

>> Reporter: THIS BILL PASSED IN FEBRUARY.

IT HAS SOME RESTRICTIVE RULES BUT THE REAL ISSUE FOR THE HOUSING PRICES COMES DOWN TO LAND, SIZE AND VALUE.

>> ANY POLICIES THAT MAKE IT MORE COMPLICATED ARE NOT GOOD.

WE NEED TO PROVIDE POLICIES THAT MAKE IT EASIER.

THE ROLE OF GOVERNMENT AT THIS POINT AND TIME SHOULD BE, ARE YOU FOLLOWING THE LAW AND ARE YOU STRUCTURALLY SOUND?

>> Reporter: TENNIS IN LOW INCOME 80 USE ARE 60% INCOME.

>>> HERE IS MORE ON WHAT THIS MEANS.

>> Reporter: THE JUDGE TOLD BOTH SIDES AFTER HE DENIED THE MOTION TO STAY ITS RULING.

HE ISSUED AN INJUNCTION LAST WEEK VOIDING THE CONTRACT.

HE SAID THERE WAS ENOUGH EVIDENCE TO SUGGEST A BIDDING PROCESS WAS RIGGED.

>> THIS IS NOT MADE A FINAL RULING.

>> Reporter: IF THE INJECTION HOLDS, THE FAIR MAY NOT HAPPEN THIS YEAR.

THERE IS ONLY NOT ENOUGH TIME TO REQUEST A BID FOR OTHER OPERATORS.

THE ATTORNEY FOR THE DISTRICT ASSOCIATION OVERSEAS THE FAIR.

>> IT'S TAKES MONTHS TO PLAY THROUGH.

>> Reporter: THE DISTRICT KNEW ABOUT THE PROBLEM MONTHS AGO.

>> THIS EMERGENCY IS A PROBLEM ESSENTIALLY OF THEIR OWN MAKING.

THEY COULD'VE ADDRESSED THIS LAST YEAR.

>> Reporter: HE IS ACCUSED US OF USING STALLING TACTICS.

HE COULD CARRY ON THE CONTRACT.

THE JUDGE AGREES.

>> I BELIEVE WE CAN'T ALLOW THIS TO GO ON YEAR AFTER YEAR.

ALLEGATIONS END UP BEING TRUE.

>> Reporter: HE TOLD BOTH SIDES TO WORK TOGETHER TO MAKE SURE THE FAIR GOES ON.

THE PRESIDENT SAYS THEY'RE WORKING TO FIND A SOLUTION THAT COMPLIES WITH THE COURT ORDER.

>> WE ARE DOING EVERYTHING POSSIBLE TO PRESERVE A FULL CARNIVAL MIDWAY AT THE FAIR.

>> Reporter: AS A SHOW OF GOOD FAITH, THEY WILL USE THE TICKETING SYSTEM TO SELL CARNIVAL TICKETS.

>> IT HAS BEEN ABOUT JUSTICE, INTEGRITY AND FAIRNESS.

>>> FOR MORE THAN 100 YEARS, SAN DIEGO ENDS HAVE NOT HAD TO PAY FOR TRASH PICKUP.

A NEW POLL SHOWS THAT MIGHT BE ABLE TO CHANGE THAT.

OUR INVESTIGATOR REPORTER SAYS ONE THING ESPECIALLY PILLS TO VOTERS.

>> Reporter: FREE REPLACEMENT OF TRASH BINS.

THE TRASH BINS ARE FREQUENTLY BROKEN BY TRASH TRUCKS.

WE ORDERED MORE THAN 17,000 REPLACEMENT BINS IN JUST ONE YEAR.

>> THEY CALL THE CITY AND THEY SAY YOU CAN PURCHASE ANOTHER ONE IN THERE LIKE, PURCHASE?

>> Reporter: THE GENERAL MANAGER OF THE EMPLOYEE UNION.

THEY PAID FOR A POLL THAT FOUND THAT PEOPLE ARE MORE LIKELY TO SUPPORT PAY FOR TRASH COLLECTION WHEN YOU INCLUDE THE PROVISION TO PROVIDE FREE CONTAINERS FOR CURBSIDE PICKUP.

IT ADDED NINE POINTS TO THE OVERALL SUPPORT FOR THE MEASURE.

>> ANY STAFF CAN TELL YOU THAT IN TERMS OF SERVICES, THIS IS A SORE SPOT WITH THOSE WHO DON'T LIKE BEING CHARGED FOR A TRASHCAN WHEN THEY FEEL LIKE IT SHOULD BE PART OF TRASH SERVICE.

>> Reporter: THE TRASH CANS WOULD NOT TECHNICALLY BE FREE.

PEOPLE WOULD BE PAYING A MONTHLY FEE FOR TRASH COLLECTION.

>> NOBODY IS TRYING TO PULL ANY PUNCHES HERE.

IN THE LANGUAGE WE SAID VERY CLEARLY THAT THIS WOULD ALLOW THE CITY TO CHARGE OR RECOVER THE COST OF TRASH COLLECTION AND THAT INCLUDED IN THE COST WOULD BE FREE TRASH CANS.

>> Reporter: THE POLL FOUND THAT VOTERS SUPPORT THE MEASURE BY A 14 POINT MARGIN AND THERE WAS NO SIGNIFICANT DIFFERENCE IN SUPPORT OF BETWEEN NORTHERN OR SOUTHERN NEIGHBORHOODS.

PEOPLE IN APARTMENTS AND CONDOS HAVE TO PAY FOR TRASH PICKUP.

THE HOPE IS THAT PEOPLE IN SINGLE-FAMILY HOMES WILL SUPPORT THE MEASURE.

THAT IS WHY THEY HAVE INCLUDED THE LANGUAGE ABOUT THE FREE TRASH BINS.

KPBS NEWS.

>>> A REPORT OF WHY SOME CORPORATIONS ARE REPORTING MAJOR PROFITS.

>>> WE HAVE OUR FIRST LOOK AT HOW e-CIGARETTES CAN AFFECT HEALTH IN THE LONG-TERM.

THEY ALTER THE INFLAMMATORY STATE OF MULTIPLE ORGANS ACCORDING TO A NEW STUDY FROM UC SAN DIEGO.

THEY LOOKED AT THE e-CIGARETTE BRAND JEWEL AND HIS TWO MOST POPULAR FLAVORS.

THEY FOUND THE DAILY USE OF DEVICES INCREASED INFLAMMATION IN THE BRAIN AND COLON.

RESEARCHERS SAY THIS RAISES MAJOR CONCERNS AS INFLAMMATION IN THE BRAIN IS LED TO ANXIETY AND ADDICTIVE BEHAVIORS.

>>> IT IS BLACK MATERNAL HEALTH WEEK.

MANY COMMUNITIES OF COLOR, THE CHALLENGE OF RAISING AND CARING FOR THEIR YOUNG ONES IS UNIQUELY DIFFICULT.

HERE IS HOW ONE ORGANIZATION IS WORKING TO CHANGE THAT.

>> Reporter: WHEN SHE FOUND OUT SHE WAS PREGNANT -- >> I WAS SCARED ABOUT WHAT TO EXPECT.

>> Reporter: SHE FOUND THAT GETTING CARE WASN'T EASY.

>> IF I HAD TO GO TO AN APPOINTMENT, I WOULD HAVE TO USE A BUS.

I DID THAT ONE TIME AND THAT WAS A LONG TRIP.

>> Reporter: THE EASTERN HALF OF THE CAPITAL, HOME TO MORE THAN 300,000 PEOPLE, LACKS ADEQUATE ACCESS TO CARE.

>> THE TOP HALF OF THE DIAMOND HAS ALL OF THE HOSPITALS IN THE LOWER HALF DOES NOT.

A PERSON WHO HAS A BABY, IT IS ABOUT A 2.5 HOUR BUS RIDE TO GET TO CARE AT THE TOP OF THE DIAMOND.

>> Reporter: 7 MILLION AMERICANS LIVE WHERE THERE IS NO UNLIMITED ACCESS TO MATERNITY CARE, WHICH CAN LEAD TO DEVASTATING OUTCOMES FOR PREGNANT PEOPLE.

>> IT IS ABSOLUTELY PAINFUL.

>> Reporter: A REPORT RELEASED BY THE CDC REVEALS THE DEATH RATE FOR BLACK WOMEN IN 2020 WAS 2.9 TIMES THE RATE FOR WHITE WOMEN.

IT IS EVEN HIGHER IN WASHINGTON.

>> WE ARE SEEING THE RIPPLE EFFECTS OF ALL OF THE PREVIOUS DAMAGE THAT HAS OCCURRED IN THIS COUNTRY AND HOW IT PLAYS OUT NOW.

>> Reporter: ORGANIZATIONS ARE WORKING TO IMPROVE THOSE OUTCOMES.

>> THIS IS THE ONLY FREESTANDING BIRTH CENTER AND THE DISTRICT OF COLUMBIA.

WE PROVIDE A WIDE RANGE OF SERVICES FOR MOMS AND BABIES OF HER PRENATAL AS WELL'S BIRTH AND AFTER BIRTH.

>> Reporter: IT ALSO PROVIDES HOUSING, TRANSPORTATION AND MENTAL HEALTH SUPPORT TO THIS UNDERSERVED REGION.

>> THE COMMUNITIES WE WORK AND HAVE A LOT OF STRESSORS.

HOUSING, ANXIETY, A LONG HISTORY OF RACIST POLICIES AND BIAS.

>> Reporter: THE ISSUES ARE COMPLICATED AND SYSTEMIC.

>> THIS IS SUCH A MULTI FACTOR PROJECT.

>> Reporter: THIS IS A KEY PRIORITY FOR THE BIDEN DEMONSTRATION.

>> REQUIRES HEALTHY MOTHERS AND HEALTHY BABIES.

>> Reporter: A FEW MILES AWAY -- >> MOTHERHOOD IS HECTIC, BUT A FUN HECTIC.

>> Reporter: THEY ARE PROOF OF WHAT SUPPORT AND CARE CAN DO.

>> WATCHING HER GROW IS PROBABLY THE ONE THING THAT I'M LOOKING FORWARD TO THE MOST.

>>> A SETTLEMENT HAS BEEN REACHED TO ADDRESS THE LONG- RUNNING PROBLEM OF POLLUTED WATER AND TRASH FLOWING ACROSS THE BORDER INTO THE UNITED STATES.

THAT RESOLVES A 2018 LAWSUIT FILED BY THE CITIES OF SAN DIEGO AMONG OTHERS.

THE BOUNDARY HAS AGREED TO SEVERAL TERMS, INCLUDING BUILDING ANOTHER TEMPORARY TO STOP FLOWS AND REMOVING TRASH FROM THE TIJUANA RIVER PANEL.

IT WILL REDUCE CROSS-BORDER POLLUTION.

>> Reporter: WE'RE LOOKING AT A LITTLE BIT OF A WARMING TREND.

ALSO, WE ARE WATCHING ANOTHER STORM POTENTIAL FOR NEXT WEEKEND.

THIS ONE DOES NOT LOOK LIKE IT WILL GET INTO SOUTHERN CALIFORNIA BUT IT WILL BRING IN SOME MORE RAIN TO CENTRAL AND NORTHERN CALIFORNIA.

WE WILL KEEP A CLOSE EYE ON THAT MOVING FORWARD.

TEMPERATURES ON TUESDAY NIGHT GET BACK DOWN INTO THE 40s.

42, EL CAJON.

IT IS STILL A BIT OF A CHILLY DAY BUT NOT AS COLD AS TUESDAY.

THERE IS STILL SOMEWHAT OF PRECIPITATION ACROSS NORTHERN CALIFORNIA.

66 OUT TOWARDS RAMONA.

BY THURSDAY THAT IS WHEN IT STARTS TO FEEL MORE OF THE WARMTH.

YOU WILL NOTICE THERE IS MORE IN THE WAY OF RAIN GETTING DOWN INTO THE BAY REGION.

THAT IS AS FAR SOUTH AS THE RAIN WILL GET ON THURSDAY.

TEMPERATURES ARE HOVERING NEAR THE 60s ALONG THE COAST.

THERE IS NOT A LOT OF CHANGE OVER THE NEXT FEW DAYS.

WE SHOULD SEE MORE IN THE WAY OF SUNSHINE OVER THE NEXT COUPLE OF DAYS.

TEMPERATURES DO WARM-UP FURTHER INLAND.

YOU SHOULD SEE A MIX OF SUNSHINE AND CLOUDS IN THE FORECAST.

TEMPERATURES HERE ARE GOING FROM THE 50s TO MAYBE THEY 60s TOWARDS THE END OF THE WEEKEND.

A LITTLE BIT OF A BREEZE PICKING UP AS WE GO TOWARDS THIS WEEKEND.

I AM METEOROLOGISTS JESSICA PASH.

>>> THEY WORKING ON A WAY TO FIGURE OUT IF THERE ARE TRACES OF LIFE ON MARS.

IT IS PART OF THE MARS MISSION TO LAND ON THE PLANET AND EXAMINE ITS ROCKS AND SOIL AND MAYBE ANSWER THE ULTIMATE QUESTION OF WHETHER WE ARE ALONE IN THE UNIVERSE.

OUR SCIENCE AND TECHNOLOGY REPORTER HAS THE STORY.

>> THE SAMPLES TO DO MOVE FASTER.

OR MAKE THE PHD STUDENT AT SAN DIEGO STATE SHOWS ME A TINY GLASS TUBE SHE USES TO SORT THROUGH MOLECULES.

SHE CAN TELL WHAT KIND THEY ARE AND WHETHER THEY ARE BIOLOGICAL.

SHE HOPES TO SEE THOSE SIGNS OF LIFE TO MATERIALS GATHERED FROM MARS.

WHERE MIGHT YOU FIND THOSE SIGNS ON THE SURFACE OF MARS WHERE THERE'S NO WATER, SOLAR RAYS AND A HIGH SALT CONTENT?

>> IT WOULD BE IN FORCE ROCKS, SOMEWHERE THAT IS SHIELDED BY THE HARSH ENVIRONMENT THAT IS MARS.

>> IT COULD ULTIMATELY PROVE THERE WAS LIFE.

THAT IS SOMETHING WE HAVE IMAGINED AND SOMETHING WE HAVE ASSUMED, BUT IT HAS NEVER BEEN PROVEN.

>> Reporter: A CHEMICAL PROFESSOR MANAGES THE LAB.

>> WE ARE LOOKING AT THE BUILDING BLOCKS SO LITTLE LEGO BLOCKS OF AMINO ACIDS.

>> Reporter: THE GLASS TUBE THE USER TO TRY TO SORT OUT THE MOLECULES HAS A CHANNEL MORE NARROW THAN A HUMAN HAIR.

MOLECULES PASS THROUGH IT AT DIFFERENT SPEEDS, DEPENDING ON THEIR SIZE AND ELECTRIC CHARGE.

THAT CAN DETERMINE WHETHER YOU ARE LOOKING AT AN AMINO ACID.

NASA HAS BEEN SUCCESSFULLY LANDING ON MARS SINCE THE 1970s AND THE FIRST IMAGES FROM THE PLANET SHOW A PERFECTLY BARREN LANDSCAPE.

THEY DID FIND EVIDENCE OF RIVERBEDS LIKELY FORMED BY PAST WATER FLOWS.

WE HAVE ALSO LEARNED THAT MARS HAS A THIN ATMOSPHERE, SHOWN BY THE STRONG LANDING ON THE PLANET.

TODAY THE MARS ROVER PERSEVERANCE IS UP THERE, IT IS PARKED ON ONE OF THOSE DRIED UP RIVER DELTAS HOPING TO COLLECT ROCKS THAT SHOW SIGNS OF LIFE.

IF WE FIND PROOF THAT LIFE ONCE EXISTED ON MARS, THAT COULD CHANGE OUR PERCEPTION OF LIFE IN THE UNIVERSE.

>> WHAT IS LIFE?

WHAT DO WE KNOW?

ALL WE KNOW IS US.

AS ANY SCIENTIST, ONE EXAMPLE IS NOT ENOUGH TO CONSTITUTE A WAY TO UNDERSTAND THE TOTALITY OF WHAT LIFE IS.

>> Reporter: FINALLY PROOF OF LIFE ON MARS COULD DEMONSTRATE THERE'S NOTHING UNIQUE ABOUT LIFE ON EARTH.

THE CREATION OF EARTH IS PART OF A PHYSICAL EVOLUTION.

>> IF YOU HAVE VOLCANOES AND WATER AND THESE ELEMENTS, GIVEN ENOUGH TIME, LIFE CAN START.

IT COULD BE THAT EASY, WE DON'T KNOW.

>> Reporter: THE MARTIANS WE IMAGINE GOES BACK TO HG WELLS WAR OF THE WORLDS.

MARS IS ONE OF THE LOGICAL PLACES TO LOOK FOR LIFE.

>> IF WE FIND LIFE ELSEWHERE, IT WILL BE BASICALLY A PRETTY COOL THING.

THE NUMBER ONE CANDIDATE IS NOT MARS AT THIS MOMENT OR EVEN THE CLOUDS OF VENUS.

THE 10 WATER WORLDS WE KNOW THAT WE HAVE IN THE SOLAR SYSTEM.

>> Reporter: HE IS TALKING ABOUT SATURN'S MOON TITAN, ONE OF THE MOONS OF JUPITER, MOONS THAT ARE BELIEVED TO HAVE A LIQUID OCEANS.

>> LET'S SAY WE FIND LIFE ON ITS OWN ELSEWHERE.

THAT SUGGEST LIFE IS EVERYWHERE IN THE COSMOS.

THAT IS WHAT I BELIEVE TO BE THE CASE.

>> Reporter: ASTRONOMY HAS FOUND 5000 PLANETS IN OTHER SOLAR SYSTEMS.

THE POSSIBILITIES ARE GREAT.

FOR NOW, WE ARE JUST LOOKING AT WHAT MAY EXIST ON HER NEXT-DOOR PLANETARY NEIGHBOR, MARS.

THE OWNER HOPES IT WILL TAKE FOLKS TO LOWER THEIR CARBON FOOTPRINT.

>> THERE IS A MUCH CHAOS AND WE KIND OF FEEL HELPLESS.

THE BIGGEST THING IS TO FOCUS ON YOUR INDIVIDUAL HABITS.

IF 1 MILLION PEOPLE FOCUS ON THEMSELVES, WE COULD REALLY MAKE A DIFFERENCE.

>> SHE HOPES TO EXPAND TO OTHER NEIGHBORHOODS IN SAN DIEGO.
