crisis

I don't know when, the original living earth under our feet is unscrupulously pulling out the blood vessels of the earth on the earth, polluting the blood of the earth, killing the cells of the earth, letting the earth shed tears, coughing violently, like dead ash.

Until there are only a handful of resources left, people wake up and dream of protecting the planet. However, "the three feet of freezing is not a cold day", once born to our planet, is now in jeopardy. What is even more ridiculous is that some people continue to deforestation for their own personal gain. As everyone knows, even if your family is rich, you will eventually die with the demise of the earth.

Twenty years ago, there were very few types of garbage. At that time, the garbage would be fine if it was sorted out. Twenty years later, many of our commonplace garbage was unheard of 20 years ago. In just 20 years, this earth-shaking change has taken place. Is this not sad?

The development of science has changed the history of mankind and promoted the progress of society. But with development and progress, mankind is facing a new crisis. Numerous factories have created thousands of wealth for human beings, but the various harmful gases that are constantly being emitted obscure the bright blue sky; thousands of cars are convenient for human travel, but car exhaust is invading all the time. People's body; household appliances make people's lives more comfortable and convenient, but the freon in the electric freezer and air conditioner has caused the hollow of the ozone layer......

The crisis has arrived, all because of the development of technology. So, are we developing or are we going backwards?
