Connected Together
Between where I am standing and wherever you are sitting,there are millions of different types of plants and animals,millions of different species,all living together in the environment,in something we call an ecosystem.Now in order for an ecosystem to be successful,in order for it to be healthy,it has to have different kinds of plants and animals-lots of different kinds of plants and animals...something we call "biodiversity".Now biodiversity sounds kind of complicated.But if you listen,it also sounds kind of nice.
This is the Earth,our world. All the living things that we know of live here,and they live in ecosystems, places like tundras, taigas, savannahs, grasslands, prairies, deserts, steppes, intertidal zones, subtidal zones, continental shelves, deep ocean zones, estuaries, deciduous forests, temperate rain forests, tropical rain forests, Artic ice packs, wetlands, marine mud flats and cities. That's a lot of environments but there are a lot of living things to fill them up.The Earth's environments are just crowded with life. Living things take hold everywhere they can.
Here's an insect living right on top of blades of grass.It's a living thing that lives on other living things.See,environments always have living parts and non-living parts.Some animals live on top of plants,some animals live in the water,some plants grow on rocks.It's all part of the ecosystem.
Nearly three-quarters of the world's surface is covered with water.So most of the world's living things live here,just one ecosystem after another.Now [as] near as we can tell,all [the] living things depend on other living things.So the more different kinds of living things in an ecosystem,the more successful it is.We call this "biodiversity" - different kinds of life.
We can think of an ecosystem as this wooden puzzle game.See all the different species? They all fit together and they depend on each other to live.And you know,once in a while a species will go extinct,it'll disappear from the ecosystem.You can see how you can lose...a few of those without too much trouble.But [if]you start to lose too many,the whole thing becomes...becomes a little...rickety.Now,where do people fit in?Oh,they fit in just about everywhere.Just about anywhere you can walk,you'll find people living because people are living things and they are part of the ecosystem.So when we go to manage an ecosystem, we have to be careful about how things fit together or there won't be a place for us.We have to be very careful...extremely careful.
Now this hasn't happened yet,but it could.
Ecosystems are a little bit like this game of sticks.You can't take one stick out without disturbing most of the other ones.The things that live in ecosystems depend on each other. They are connected.It's kind of cool!

The Beautiful Landscapes of Shennongjia
Long ago in Ancient China,there was a mythical figure known as Shennong.Not only did Shennong bring agriculture and the use of herbal medicine to China;he also invented agricultural tools and techniques,and the Chinese calendar with its 24 solar terms.
It is said that the home town of Shennong was a forest in Hubei Province,which today is known as"Shennongjia".This beautiful and diverse region covers an area of 3,253 square kilometres of north-west Hubei Province.It gives shelter to over 1,000 species of medicinal plants,many of which are rare and unique to Shennongjia.Here,mountain slopes are covered with trees,some of which grow up to 40 metres tall.In summer,pink and violet flowers lend splashes of colour.These are some of its most breathtaking landscapes.The magnificent Shennong Peak rises to 3,105 metres above sea level.
Banbiyan is famous for its stone forest,as well as its bamboo forests and grasslands that flood with flowers.The stone forests of Fengjingya stand against a background of green mountains that reaches as far as the eye can see.When it rains,the tops of these mountains look like islands floating on a sea of clouds.Come to Shennongjia to enjoy its beauty and experience the legend!
