Dinosaurs were the primary form of life on Earth for billions of years. Other mammalian life forms existed for millennia after the dinosaurs disappeared. Humans have existed on Earth for only about 300,000 years. That's a blink of an eye in terms of this planet's existence.
Many things have happened to this planet-meteor strikes, ice ages, massive volcanoes, the original singular continent of Pangaea splitting apart. The collision of at least two of the new continents created the Himalayas.
The new crisis, as humanity calls it, is climate change. Our extensive pollution of the ocean and the atmosphere has done damage and the increase in ocean temperatures have caused increasingly intense storms like hurricanes, winter blizzards and ice storms. Summer tornadoes and intense heat are also worsening.
But overall, we are not harming the planet in a long term way. We are harming ourselves as a species. The planet has been here for billions of years, and our momentary presence here will not do any long term damage from which the planet cannot recover.
In cosmic terms, we just got here. If we continue living and acting as we are, we'll be gone just as quickly, and this planet will continue on without us. The next species will move up to the primary form of life.
