Diamonds come from mines, so issues related to mining apply to diamonds, too.
The actual use of diamonds has no significant impact. However the demand for diamonds has an impact on the eviornment because diamonds are mined from the earth.
Looking after the earth is called environmental conservation or environmental stewardship. It involves taking actions to protect and preserve the natural environment and its resources for future generations.
To date there are few if any environmental concerns with solar energy. One stretch on this might be this: what types of energy are used to create solar energy components. And, are these components "earth friendly". So far solar engineers have seen no environmental related protests.
No, diamonds don't surround the earth's mantle. Diamonds are formed within the earth's mantle, and are rare.
The earth is mined to get diamonds.
Diamonds are formed deep within the earth's mantle.
Diamonds can be found on every continent on Earth, except Europe and Antarctica.
Diamonds have to be mined by humans
Natural diamonds that erupt to the earth's surface were formed with the earth. Diamonds that come to earth from space may have been formed before earth: that research hasn't been documented to date.
Diamonds are erupted to the surface of the earth by volcanic pipes.
All diamonds are erupted to the surface of the earth from deep within the mantle, where diamonds are formed. Diamonds are mined on every continent on earth except Europe and Antarctica.
There is an estimated total of about 1,200,000,000,000 carats of diamonds on Earth, which is roughly equivalent to 240,000 metric tons. Most of these diamonds are located deep within the Earth's mantle and are not easily accessible.
