How many years can the earth last before perishing

..5 billion years later. The Earth is speculated to have survived for 4.6 billion years, but how long will it live?

Scientists believe that if the Earth is allowed to move freely, it may exist forever, but if other external factors interfere with it, the Earth may have an end of life. The external factor is the sun in the first place, because it is the closest planet to the earth and can have a destiny on the right earth That is to say, all the energy and power on the earth come from the sun, and once the sun has three long and two short, it is bound to affect the earth. Before the 30s of this century, people always thought that the sun would one day burn out, turn from white to orange and then to red, and finally become a dark star that was silent, but its brilliant life.

In the 30s, when physicists learned the mystery of the sun's light, the situation was very different. It turns out that the Sun's energy comes from its thermonuclear reactions, and the Sun's lifetime will pass through the gravitational contraction phase, the main-sequence star phase, the red giant phase, and the compact star phase. The main sequence phase is the period of stability of the Sun.

This phase will last for 10 billion years. At present, the sun is only halfway through and is in middle age. Once the Sun reaches the red giant stage, then the end of the Earth is coming.

After 40 million years, the Earth will disintegrate due to changes in the magnetic field.

Once people continue to destroy the planet, then less than 10 years will be sitting

The fate of the earth is determined by the sun, and as long as the solar energy stabilizes, it will not perish, and the sun is still middle-aged, and it has a long life, and so is the earth.

The earth will not be destroyed in billions of years, according to scientific research, the earth is only a very young planet in the vast universe, and the sun has a lifespan of 10 billion years. If the sun is an old grandfather, then the earth is just a middle-aged man.

The earth is in its prime, and it is not surprising that the earth will not be destroyed in the next few billion years. Therefore, our human position in this ring is very important, reducing the emission of exhaust gases and carbon dioxide and other gases, and reducing the greenhouse effect in order to prolong the life of the earth.

Ways to protect the planet.

1. Save resources and reduce pollution.

1. Save water, electricity, gas and natural resources.

2. Use less detergent and more soap to avoid the chemicals in the detergent from polluting the river water.

Second, green consumption and environmental protection choices.

Use unleaded gasoline, cadmium-free lead batteries, phosphorus-free laundry detergent, reduce water and air pollution.

3. Reuse and reuse.

Use as few or no disposable items as possible, and use durable goods more to save resources and reduce pollution.

Fourth, classification ** recycling.

Waste will be sorted and put into waste, turning waste into treasure, recycling resources, and benefiting mankind.

5. Protect the coexistence of all things in nature.

Do not hunt or eat rare animals and protected animals, care for and protect wild animals, plant trees, plant a variety of flowers and plants, and take care of every inch of green space, every flower and plant, and every forest.

The earth will live forever.

The end of the earth has arrived, the Antarctic ice crack is infected by the virus, the new coronavirus has evolved, and the earth is not long left.
