【B】It has been more than 30 years since one special group heldthe first beach cleanups in the USA. Some of the big cleanupswere in Texas, Oregon, New Jersey, and California. Since thattime, the idea has grown into a common activity all over theworld. Now, more than 150 countries come together to take partin beach cleanups each year, and Taiwan is one of them.         People join beach cleanups because they want to take careof the world and its oceans. However, there is a problem. To getmore people to come to the cleanups, some organizers give outfree lunches and bottled water. As a result, the bottles add to thetrash. To fix this, people should bring their own lunches andthermoses to cut down on the number of used bottles. After all,where does trash come from if people don’t even have things tothrow away?
