Keeping Our Earth Clean Across the world, places are increasing their efforts to recycle and help the environment. Recycling is when trash is reused and not thrown away. In recent history, more and more cities and countries have started recycling. These places have developed their recycling programs to stop our Earth from being covered with trash and black, dirty air. According to the Environmental Protection Agency in the United States, recycling also helps save energy. The agency encourages the recycling of glass andplastic bottles, paper, and aluminum cans. Many European countries have strong recycling programs as well. Austria, Germany, and Norway are well known for being leaders in recycling, and South Korea and Wales are countries that have a lot of recycling as well. There are many reasons why some countries recycle more than others. The fact is that these governments support recycling, and they are aware of its importance. There is also a lot of money spent on recycling. However, it is also necessary for people to try hard to recycle what they can from their own homes. Other ways to fight the waste problem also exist. Many cities place recycling bins on their streets. There are recycling projects across some cities--and in these projects, companies advertise the need to recycle. This helps keep the city streets clean. Electric cars are another way to keep the environment clean. The motors of these cars are electric. They get their power from electricity and batteries rather than from gas. The hope is that eventually all cities in all countries will recycle and make our Earth a cleaner place. We must protect nature and never stop thinking about how to protect it. So think before you throw away something that can be recycled!
