"Global Warming" has been talked about for over a thousand years.
There are many causes of global warming, one of which is often referred to as the "greenhouse effect".
This means that the planet's atmosphere heats up the planet's surface because it absorbs radiation energy.
And this is by no means unique to Earth.
The difference is only in our cognition. There are not only living beings on the earth, but also the "human beings" who are self-proclaimed as the spirit of all things.
With the rapid development of human beings, population expansion and environmental pollution are inevitable. Many studies have pointed out that it is human activities that increase the content of greenhouse gases in the atmosphere, such as burning fossil fuels, water vapor, carbon dioxide, methane and other gases emitted. When you fart or burp, you will also emit a lot of body waste.
So...the human mind can become extreme all of a sudden.
Not only have I never eaten beef, I've never even seen a real cow.
It was only by looking through the history of zoology that I knew that there were once many cows on earth.
Cows once helped humans cultivate land, and provided milk and meat. Even if the skin and hair on the body are useful, it can be said that the whole body is a treasure.
Now, cattle have become treasures.
Only the rich can own it.
