Humpback whales can sing
Those silly birds in the rain forest are so cute
Mankind has no predators, most diseases have been controlled, and how to produce food on demand, no longer restricted
When the symbiotic algae leave or die, the coral will bleach, and the bleached coral will eventually be swallowed by seaweed. White coral is a sad story
Changes in the carbon content of the atmosphere have always been the natural enemy of the earth’s climate stability
Pessimistic predictions to maintain the status quo:
In 2030, the Amazon rainforest will degenerate into a dry savanna, a large number of species will be extinct, and the global hydrological cycle will change. There will be no ice in the North Pole in summer, and the solar energy reflected to outer space will decrease, accelerating global warming.
In 2040, the Arctic permafrost will melt and release methane, a greenhouse gas that is several times more powerful than carbon dioxide, which will rapidly increase the speed of global climate change.
In 2050, the sea temperature is getting higher and the acidity is getting stronger and stronger, coral reefs all over the world will die, and the number of fish will be greatly reduced.
In 2080, the global food supply is facing a crisis. Excessive farming causes the soil to become barren, pollinator insects disappear, and the weather becomes more and more elusive.
In 2100, the global temperature will increase by 4 degrees Celsius, most of the earth’s land is no longer inhabitable, tens of millions of people have been displaced, and the sixth mass extinction is about to take place.
Solution:
Maintain species diversity
Reduce population growth. It is especially exaggerated that Japan’s population will no longer grow after the millennium, extend the time girls go to school, reduce population growth, and capital will cry after hearing this.
Renewable energy is a promising direction
Palau, Pacific island country, want to go
Serengeti Prairie, want to go
Cut down on meat, most people can’t do it
Food use technology to increase production
The 94-year-old is still optimistic in the end
