16．Time is in the year 2095．It is reported that a comet（彗星） is rushing towards the Earth．Most of it will miss our earth，but two pieces will probably hit the southern half of our planet
On 15 July，a piece about four kilometers wide enters the Earth's atmosphere with a massive explosion（爆炸）．About half of the piece is destroyed，but the remaining part hits the South Atlantic at 200 times the speed of sound．A hole is made in the sea bed．Huge waves spread outwards from the hole．The wall of water，a kilometer high，rushes towards southern Africa at 800 kilometers an hour．Cities on the African coast are totally destroyed and millions of people are drowned．
Before the waves arrive in South America，the second piece of the comet hits Argentina．Earthquakes and volcanoes（火山爆发） are set off in the Andes Mountains．The shock waves move north into California and all around the Pacific Ocean．The cities of Los Angeles，San Francisco and Tokyo are com pletely destroyed by earthquakes．Millions of people in the southern half of the earth are already dead，but the north won't escape for long．Because of the explosions，the sun is hidden by clouds of dust，temperatures around the world fall to almost zero．Crops are destroyed．The sun won't be seen again for many years．Wars break out as countries fight for food．A year later，no more than 10 million people remain alive．

Pandas live in the forests and mountains of Southwest China．They mainly live on bamboo，and each panda needs to eat a lot of bamboo every day．The area of bamboo is becoming smaller for many different reasons，so pandas have less and less land to live on．Pandas don't have many babies，and baby pandas often die，The situation is becoming very serious．
