We make all kinds of rubbish every day. Some artists have new ideas on how to recycle (回收) rubbish. Let’s have a look.

	What’s this? This is a model of Bumblebee. An Indonesian man called Yusuf made it at home. He used recycled waste such as plastic bottles.
	Look at this! Canadian artist Benjamin made it. When the tap is on, there is no water but it’s full of plastic waste. It wants to ask people to end plastic (塑料) pollution.
	Is it a walking robot? No, this is a big statue (雕塑). A German artist, HA Schult, used wasted washing machines to make it.
	This is a “panda” made of recycled shoes. All the things are collected from beaches in Kenya. This panda wants to tell people to take care of animals in danger.

The number of people living in the rainforest is rising, but the rainforest itself is becoming smaller!

During the 20th century, huge areas of rainforests were cut down. More and more people in Brazil and Indonesia moved into rainforest areas to find land for living. Local farmers cut down trees to grow crops (庄稼). Large companies have also moved into the rainforests to develop their factories.

The problem is that the area of the rainforest is becoming smaller and smaller. Scientists say that destroying (破坏) the rainforest is ▲ the earth and should be stopped. But why? Rainforest plants help to clean the air. What’s more, different parts of rainforest plants can be used to produce useful medicines and may be the key to solving serious health problems.

So how can we solve the problem? Governments can make some rules to protect their forests. Companies can create jobs elsewhere, so that fewer people have to live and work in the rainforests. Farmers are encouraged to plant crops in certain areas, and this helps to stop the soil from being washed away and produces better crops.

More than half of the plants and animals that live in the rainforest can’t be found anywhere else in the world. It is important to make sure that these forests are used well and protected by people.

①What does it mean to be green? Green is more than just a color. It also means taking special steps to protect the environment. Buying a green product is a small step everyone can take. Deciding whether a product is green, however, isn’t always easy. We need to consider the whole life cycle of the product even after it’s of no use. Here is what we may keep in mind.

②The materials of a product are usually our first focus (关注). What is it made of? Are there any harmful chemicals in it? Green products are made of more natural materials which are free from harmful chemicals, so they can be good for our physical health.

③Packaging(包装) is important. How is a product packaged? Is it over packaged? We’d better choose glass metal and paper packaging, as these can be reused or more easily recycled. We can also look for less packaging or even choose unbagged products whenever possible.

④Location matters. Where was a product produced? Where are we buying it? Think about how much energy was used to get it to us. Try to choose local products. When it comes to food, it is a good idea to order directly from local farmers, shop at markets and buy fruits in season. Buying from stores near our houses is also a good choice, because we can go there without driving a car.

⑤Look into what the company tells us about their product. It’s easy to say that a product is “green” or “all natural” but the words may be too good to be true. So much of the information about a product should be taken with a grain of salt. After all, companies try to make us believe that their products are environmentally responsible.

⑥The greenest thing is certainly the one we don’t buy. Things like food and clothing are necessary for life. But many others are not. Better than buying is choosing to leave an unnecessary product in the store and doing without. It sends a message to the producer, keeps money in our pockets, reduces waste and keeps the planet healthy.
