Introduction
The environment is all it that us surround and that we care to maintain our city clean. The Earth provides resources that are exploitable by humans for useful purposes. The Earth is certainly the most familiar planet, though it has only been a few hundred years since we fully realized it was a planet. There are a lot of things that affect our planet in a bad way but thegood news is that everyone can help to reduce them and do their bit for the environment.

THE NATURAL ENVIRONMENT
The natural environment encompassesIt is an environment that encompasses the interaction of all living species. It is an environment that encompasses the interaction of all living species. The concept of the natural environment can be distinguished by components:
* Completeecological units that function as natural systems without massive human intervention, including all vegetation, microorganisms, soil, rocks, atmosphere and natural phenomena that occur within their boundaries.
* Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, notoriginating from human activity.
The natural environment is contrasted with the built environment , which comprises the areas and components that are strongly influenced by humans. A geographical area is regarded as a natural environment.
It is difficult to find absolutely natural environments, and it is common that the naturalness varies in a continuum, from ideally 100% natural in one extremeto 0% natural in the other. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform.

THE EARTH
The Earth is the third planet from the Sun. and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets.
The Earth formedapproximately 4.54 billion years ago by accretion from the solar nebula, and life appeared on its surface within one billion years. The planet is home to millions of species, including humans. ` The Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which,together with Earth's magnetic field, blocks harmful solar radiation, permitting life on land. The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist.
THE LIFE
The Evidence suggest that life on Earth has existed for about 3.7 billion years. All known life forms share fundamental molecular mechanisms, and based on these observations, theorieson the origin of life attempt to find a mechanism explaining the formation of a primordial single cell organism from which all life originates. There are many different hypotheses regarding the path that might have been taken from simple organic molecules via pre-cellular life to protocells and metabolism.
Although there is no universal agreement on the definition of life, scientists generallyaccept that the biological manifestation of life is characterized by organization, metabolism, growth, adaptation, response to stimuli and reproduction. Life may also be said to be simply the characteristic state of organisms. In biology, the science of living organisms, "life" is the condition which distinguishes active organisms from inorganic matter, including the capacity for growth,...
