reenhouse effect. all that is mentioned above has a bad impact on the ecosystem .now, many animals aredying out. we are suffering from unhealthy food and water, we are faced withharmful rays and global warming. it was ourselves who had made a series oftroubles. as you can see, we are the final victim.above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. so, it is our duty to protect theenvironment ,but what should we do to protect it?in my opinion, the first and important thing is tounite all forces ,that is to saygather all hearts together. next we shouldprotect and plant more trees, which can dispose of the dust in the air. as forfamilies, it is effective to ride bicycles rather than drive cars. don’t litteranywhere as you like. in addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. we’d better call on everyone aroundus to lead a lowcarbon life, as it may make a difference to the environment.thus, it’s high time that we did something to improveour surroundings. everybody should raise the awareness to protect our motherearth. let’s appeal to more people to join us.all in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.
