Balloons are a symbol of celebration. People love to release (放) colorful balloons for special events (事件), such as f【小题1】 and ceremonies. Colorful balloons may look pretty, b【小题2】 they can bring about some serious problems.

After balloons are released, they can end up hundreds of kilometers away f【小题3】 where they were released, causing great harm to the environment and wildlife. They can fly a【小题4】 everywhere, including waterways, oceans, mountains and farmlands.

Well, in our daily life, there are two types of balloons. Most of the balloons we use are latex (乳 胶) balloons. In fact, i【小题5】 will take them six months to four years to decompose (分解) and they can cause pollution before they do. The other one is Mylar (聚酯薄膜) balloons. They are a k【小题6】 of plastic balloons which can not be decomposed and can stay in the environment forever. Similar to plastic bags, the Mylar balloons break into smaller pieces in the sun.

All of these materials can add to the amount of plastic w【小题7】 in our environment. At the same time, it can result the death of animals. Sea animals, such as whales, sea birds often mistake balloon pieces for food, and if eaten, those pieces can make them h【小题8】 to breathe and then cause them to die. Even worse, some birds are collecting balloon pieces, thinking that they are food, and even f【小题9】 them to their babies

So, don’t release balloons any more in order to r【小题10】 the pollution and protect animals. Small step we take can make the world better, healthier and cleaner.

If you don’t know how to fix the Earth, please stop b【小题6】 it!” The six-minute speech silenced all the people and made them fall into deep thinking.

After that speech, Susan began to lead “two lives.” On the t【小题7】 days, she was a schoolchild. But during her vacations, she s【小题8】 internationally about the environment.
