As biological processes are not thermodynamically reversible, life on Earth is not actually sustainable. Eventually entropy will get the better of us and life as we know it will not be able to exist.
For example, the Earth is due to "run out" of Carbon dioxide in about 500 million years (meaning that there won't be enough carbon dioxide for photosynthesis to take place).
Life
Earth is special because it can sustain life, it has all of the conditions things need to live. Other planets may contain life but as far as science knows, no because the conditions aren't correct for life...Most plants don't have any type of water for life or some resource of food and the air surrounding the plants aren't good for you.
Crust,Mantle,Core are the three main parts of the Earth.
All life is the result of evolution.
Life?.. you know, birth to death etc..
1- Global Warming 2- Pollution
Three interconnected factors that sustain life on Earth are the presence of liquid water, a suitable atmosphere with the right balance of gases for respiration, and the Earth's distance from the sun to maintain a habitable temperature range.
Stars are suns and cannot sustain life. Earth is well, earth, and it CAN sustain life.
we can sustain life on earth if we keep on recycling and pick up rubbish.
While Earth can no doubt sustain life in the case of humans and every animal alive to date, it is still a question as to whether earth can sustain life or not.
star is a huge mass of gas, where as earth is a planet
Apart from water, you need oxygen in the air to sustain life on earth. With these two indispensable features, both mankind,animals and botanical reserves sustain life on this planet.
The Earth can sustain life due to its ideal distance from the sun, presence of liquid water, protective atmosphere, and stable climate. These factors create conditions that support the existence of diverse forms of life on our planet.
No planet except the planet Earth is known to sustain life till date.
Earth is the only planet in our solar system that can sustain human life.
Earth can sustain life. The Moon can not.
The earth has several factors that allow it to sustain life while its sister planets cannot. The most important of which is its location from the Sun. Earth lies within the "Goldilocks Zone" which is a distance from a star that allows for proper temperatures to maintain life. Deviation too far in either distance can make it too hot, or too cold, to sustain life.
