3、PLAYA GRANDE, COSTA RICA? This resort town was long known for Leatherback Sea Turtle （棱皮龟）National Park, nightly turtle beach tours and even a sea turtle museum．However, on a beach where dozens of turtles used to nest on a given night, scientists spied only 32 leatherbacks all of last year．

       With leatherbacks threatened with extinction （灭绝）, Playa Grande's turtle museum was abandoned three years ago and now sits among a sea of weeds．And the beachside ticket office for turtle tours was washed away by a high tide in September．"We do not promote that 'as a turtle tourism destination anymore because we realize there are far too few turtles to please,” said Alvaro Fonseca, a park ranger （管理员）．

       Even before scientists found temperatures going up over the past decade, sea turtles were threatened by beach development, drift net fishing and Costa Ricans' interest in eating turtle eggs．Btu climate change may cause the most serious harm to an animal that has lived in the Pacific for 150 million years．

       Sea turtles are sensitive to numerous effects of warming．They feed on reefs, which are dying in hotter seas．They lay eggs on beaches that are being covered by rising seas and more violent waves．

       More uniquely their gender （性别）is determined, not by genes but by the egg's temperature during development．Small rises in beach temperatures can result in ail-female populations, obviously problematic for survival．If the sand around the eggs hits 30 degrees Celsius, the gender balance shits to females: at about 32 degrees they are all female．Above 34, you get boiled eggs．

       On some nesting beaches, scientists are artificially cooling nests with shade or irrigation and trying to protect broader areas of coastal property from development to ensure that turtles have a place to nest as the seas rise．

22、COOL INVENTIONS

From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go．This battery-powered, zero-emission （meaning it doesn't pollute the air） vehicle runs mainly on renewable energy．Solar panels on the Eclectic's roof absorb sun rays when you're driving．On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked．The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged．Zipping （迅速行进） around the neighborhood has never been better.

Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank （箱） with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries．There are two sets of metal electrodes （电极） inside the water tank．Water contains ions （离子） that carry negative and positive charges．These ions complete a charge between the electrodes, creating enough energy to power the clock．Just refill the tank every few weeks, and this clock will keep on ticking.

Bloodhound SuperSonic Car （SSC） will be the first car to attempt to break the l,000-mile-an-hour barrier．（The current record is 763 miles an hour.） A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine．Then a rocket fires up, pushing the SSC past 1,000 miles an hour．In order to keep the car streamlined （流线型的）, the driver lies back at a 45-degree angle.

You're having a blast at your friend's birthday party．But when it's time to bring out the cake, everyone crowds around, blocking your view．No worries．Throw the Triops into the air, and this clever camera captures the view from above．The Triops can take three pictures at once, each from different angles．You can also record sounds and command the Triops to start shooting whenever it hears that noise．That's one smart camera.
