世界地球日英语演讲稿（精选3篇）
Good morning, everyone ！
April 22nd will be the 41st “Earth Day ”.This year’s theme is to live with low carbon.
Earth Day originated from America. On April 22nd ,1970,US Democratic Senator ?Gaylord Nelson ,and a student from Harvard University-Dennis Hayes,organized an activity named “Earth Day”. Many people in the USA joined them. The purpose was to callon all the people to keep our environment clean and protect our earth .
The earth is our common home ,but some of our activities cause serious damages to the earth .Now ,forests,lakes,wetlands are disappearing at an alarming rate;Coal,oil,gas and other non-renewable energy sources face depletion due to over-exploitation;Emissions of greenhouse gases cause global warming;ice caps in the Arctic and the Antarctic are melting down and sea-level rises which threaten human survival and development .
On Earth Day, 175 world leaders met at the United Nations to sign the Paris Agreement, a historic pact to curb the carbon emissions behind climate change. Several speakers kicked off the ceremony by describing what's at stake, culminating with an urgent, cogent plea from new Academy Award-winner Leonardo DiCaprio.
"Yes, we have achieved the Paris Agreement. More countries have come together to sign this agreement today than for any other cause in the history of humankind, and that is reason for hope," DiCaprio said, praising the first international treaty that commits both developed and developing nations to cut greenhouse gas emissions. "But unfortunately the evidence shows us that it will not be enough. Our planet cannot be saved unless we leave fossil fuels in the ground where they belong."
"You know that climate change is happening faster than even the most pessimistic of scientists warned us decades ago. It has become a runaway freight train bringing with it an impending disaster for all living things," DiCaprio said. "Think about the shame each of us will carry when our children and grandchildren look back and realize we had the means of stopping this devastation, but simply lacked the political will."
"We can congratulate each other today, but it will mean absolutely nothing if you return to your countries and fail to push beyond the promises of this historic agreement. Now is the time for bold, unprecedented action. My friends, look at the delegates around you. It's time to ask yourselves which side of history you will be on."
老师们、同学们：大家早上好!
明天就是4月22日，是一个特别的日子，有谁知道是什么日子?(世界地球日)今天我国旗下讲话的主题就是“世界地球日”。
世界地球日活动起源于美国，1970年4月22日，美国首次举行了声势浩大的“地球日”活动。这是人类有史以来第一次规模宏大的群众性环境保护运动。作为人类现代环保运动的开端，“地球日”活动推动了多个国家环境法规的建立。1990年4月22日，全世界140多个国家、2亿多人同时在各地举行多种多样的环境保护宣传活动。这项活动得到了联合国的首肯。从此“地球日”成为了“世界地球日”。
大家都知道，由于人类向自然界过度的索取，已经导致了大自然无情的报复：台风、暴雨、暴风雪、洪涝、干旱、森林大火、地震、海啸等灾情每年都在发生，全世界每年应台风、暴雨、洪涝、干旱、森林大火、地震、海啸等灾害死亡的人达到几百万人。所有这一切都在向人类发出警示：人类在破坏地球环境的同时，也在毁灭着自己。人类只有一个地球，尊重地球就是尊重生命，拯救地球就是拯救未来。
4月22日(也就是明天)是“世界地球日”，世界地球日活动旨在唤起人类爱护地球、保护家园的意识，促进资源开发与环境保护的协调发展。我国从1990年开始，每年4月22日也都举办“世界地球日”的纪念活动。
作为小学生的我们，该如何做呢?每天早晨和中午，我们都能看到同学们在打扫卫生，拣拾废纸，用自己的双手去保护校园环境的优美。但是，校园里仍然存在着一些问题：有的同学随便乱丢废纸、乱丢食品袋废弃物;有的同学随便在草坪上行走践踏草坪;有的同学在学校食堂吃饭时候把饭菜、汤掉落在地上，不及时清理干净，造成了的浪费，污染了校园环境!
同学们，环保意识是现代人的标志。做为21世纪的主人，我们要有时代责任感。心系全球，着眼身边，立足校园。不随地乱扔废纸、垃圾;不随便在草坪上行走践踏草坪，多弯弯腰捡捡纸屑，节约用水、节约用电、节约用纸，看见有人乱扔废纸、垃圾，破坏校园环境的行为及时批评并报告老师。爱护花草树木，从小事做起，从身边的事做起，从现在做起，保护地球母亲，让我们的家园更加美丽!
