For thousands of years, people have used plants to make medicines. They used different parts of the plants —the roots, the leaves, the flowers, and the bark (树皮). Today, doctors have rediscovered more medicinal (药用) values of some plants. Let’s look at some examples.

Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems.

In some areas, malaria has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria.

In Germany, some scientists studied garlic (大蒜) for four years. They found that it helps prevent the build-up of plaque (血小板) because too much plaque is bad for health. This very common plant continues to be studied.

As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent.

Maybe you can not imagine what a hotel made of trash looks like. But in Rome, Italy, there is a campaign called Save the Beach that has created a hotel out of 12 tons of trash in order to raise awareness (意识) of our waste.
Save the Beach is an environmental awareness campaign set up by the makers of Corona Beer. They collected all the trash from all the beaches all across Europe. Then they built the special hotel.
It was reported that the hotel was fully booked (预约). And it was open only for four days there in early June, the same time as World Environment Day. Next to the “trash hotel” was the slogan of Save the Beach. It said, we have built the first hotel made of trash in the world. This will be the future of our holidays if we do nothing to protect our beaches.
The hotel was built just to show the damage we were causing to the sea and the coastline (海岸线). We live in the time of trash and we are running the risk of becoming trash ourselves. Do we really want such a world?
The trash hotel in Rome was just the beginning to support healthy, clean and trash-free beaches all across Europe by Save the Beach. Maybe there will be more surprising ideas in the future. Let’s wait and see.
