世界地球日英语演讲稿（精选3篇）
尊敬的老师，亲爱的同学们：
大家早上好!
我们是四年级2班的同学，今天我们演讲的题目是：我们只有一个地球。
美丽的地球是宇宙中最耀眼的星球。她是人类的母亲，是生命的摇篮。她用母亲般的慷慨无私奉献着一切财富，我们才有了过去，我们才有了幸福舒适的生活。可是如今地球母亲为了照顾我们已失去了昔日的风采!
当我们在课文中读到，中华民族的摇篮黄河，如今已经成为悬河、祸患的时候;当我们从新闻里听到森林的数量在日益减少的时候;当我们从报纸上看到城市的汽车数量在增加的时候;当我们亲身感受到新鲜的空气被污染了的时候;我们深深地感到，地球母亲在伤心、在哀叹、在哭泣……
随着人类文明、科学技术迅速发展。卫星升空，光缆深埋，计算机和信息网络使人们的交流更加方便。但是，在人类科技不断发展的同时，也给地球带来了巨大的伤害。 掠夺式的滥用资源，破坏植被，一片片的森林变成了荒漠，小鸟失去了自己的家。人口的迅速增长，占去了大量的耕地，使许多野生动物无家可归。工厂排放出的污染物，把鱼，虾活生生的毒死。还有些人为了谋取更多的钱财，不惜杀害国家的保护动物，用它们的皮毛制成物品换取更多的金钱。稀有动物的杀害导致了食物链的破坏，直接关系到人类的生存。
“我们这个地球太可爱了，同时又太容易破碎了!”这是宇航员遨游太空目睹地球时发出的感叹。地球是渺小的。它是一个半径只有六千三百多万千米的星球。在群星璀璨的宇宙中，地球就像一叶扁舟。它只有这么大，不会再长大。
地球所拥有的自然资源也是有限的。拿矿物资源来说，它不是上帝的恩赐，而是经过几百万年，甚至几亿年的地质变化才形成的。地球是无私的，它向人类慷慨地提供矿产资源。但是，如果不加节制地开采，必将加速地球上矿产资源的枯竭。
其实保护地球很简单。我们只须在砍伐树木的同时，种下一颗爱的树苗;只须在捕猎时，给动物的孩子留一条生路，只需少用一次性制品，节约用水，节约用电、节约用纸。学会资源的循环再利用，这就已足够了，正如那句俗语所说，每人一小步，人类一大步。
同学们，打开电视机吧，“环宇探索”、“地球与人”等节目将增进我们对地球妈妈的更深了解;
打开报纸、书籍，走进互联网吧，许多信息将指导我们怎样去抚慰、爱护地球母亲……
让我们真心付出， 从现在做起，从小事做起。以实际行动保护好我们亲爱的母亲——地球!因为，我们只有一个地球!
我的演讲到此结束，谢谢大家!
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."
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 .
