From the natural point of view, we should take care of the natural biological and abiotic environment, actively protect endangered species and high-risk species, cherish rare creatures, cherish various ecological environments and protect the existing natural heritage.
From the aspect of human society, we should do more: save water, electricity, grain, population and resources, rivers and lakes, non-renewable resources such as oil, natural gas and coal mines, protect rural ecological environment, actively develop and improve rural and urban structures and ecological environment, protect national resources, cherish peace against nuclear war, all wars, human rights, protect human heritage and develop future industries.
Only when human beings have restrained their own shortcomings and truly reached the stage of not destroying nature for the benefit and truly living in harmony with nature, will human beings coexist with the earth forever.
There are many things to do to protect the earth, but the essence is that we should always keep a positive attitude and treat everything around us correctly in order to make meaningful things unconsciously!
Thank you.
