2. Natural resources are elements of nature that are useful to
humans in the development process of civilization, survival
and comfort of society in general. Can be renewable, such as
energy from the sun and wind. Have water, soil and trees
being considered limited, are called potentially renewable.
And yet the non-renewable, such as oil and minerals in
general.
RENEWABLE: resources are not exhausted in nature, since
its renovation is permanent.
NOT RENEWABLE: resources are exhausted in nature
because its capacity for renewal is not made in time for the
man, as this consumes at a rate that nature is not capable of
producing them.
Natural resources?
4. SUN
By SUN receive light and heat, as this star is close to the Earth
and the emitted rays can reach us. This light, to reach the
Earth, provides heat for the living and non-living beings.
The earth rotates around its own axis (rotational movement)
within 24 hours, which provides that the existence of days
and nights, as during this movement of the Earth's surface is
directed to the Sun (day) and the other party does not receive
sunlight (night).
Without the Sun, the Earth would not be lit
and it would be very cold, maybe not existed life
on our planet.
5. WATER
WATER is very important for life on the planet, as it takes up
most of the Earth's surface.? But not all water is fresh and
ready for human consumption. On the contrary, the greatest
amount of water on the planet is salt, coming from the seas
and oceans If we made a representation of the amount of
fresh and salt water on the planet would look like?
Blue (Freshwater) - Green (Saltwater)
6. WATER
Today, the supply of water on the planet is compromised,
due to the pollution caused by man. Every day large
amounts of waste, sewage and chemicals are dumped in
rivers and seas, polluting the waters.
If we do not create awareness that nature must be
respected, there is the risk of not having more water on the
planet.
7. AR
The AR is a natural resource composed of different gases,
such as oxygen; is essential to life, because we need it to
breathe, fueling our body the quantities necessary for its
operation.
Large amounts of pollution, caused by man, has also harmed
the quality of the air we breathe. So it is common to see
people with respiratory problems.
The industries are quite responsible for
air pollution and fires and the increase of
cars driving the cities.
8. SOiL
The soil is part of the earth's surface in which we live, is
the ground we walk on. Through Soil can cultivate
materials necessary for human survival, such as food.
Good Soil, in perfect condition, animal shelters species
such as worms, armadillos, etc.
When the soil is destroyed, the winds and the rains drag
components to other sites, causing erosion or large holes.
Thus, the Solo is unprotected, deforested,
there is little possibility of housing larger
plants.
9. Living things are also nature's resources.
To conserve natural resources, we must maintain some
protective attitudes to them, such as:
- Do not pollute the natural environment and avoid
throwing garbage in the streets, roads, lakes, rivers and
seas;
- Not cut down trees;
- Make less use of cars, looking walking,
cycling or in transport public;
- Not killing living beings, etc.

12. Advantages of the use
of renewable energy
• There are pollutants.
• Are inexhaustible
(renewable)
• Wide global
distribution.
• Less disruption of
ecosystems.
Disadvantages of the use
of renewable energy
• They can not by itself
ensure that meets the
production requirements.
• It is uncertain.
• Storage difficulty.
• There are adapted for
transport.
• High costs of investment.
13. IMPORTANCE OF RESOURCES
NATURAL AND ITS CONSERVATION
Natural resources are of great importance to the world
economy. Without these resources would be impossible
for the survival of man on Earth.
The socio-economic development process of a country
should be based on natural resources. It is intended that
such use is responsible and sustainable, so that future
generations are entitled to the same resources that we
today possess.
14. DEVELOPMENT
SUSTAINABLE ...
• You need a good management of resources by
governments;
• Countries must be understood internationally to not
cause damage worldwide;
• Theoretically, provided that a proper plan, which prevents
human action harmful continuity of renewable resources
can happen;
• Conveniently recycle non-renewable resources, increasing
the time of its existence is possible.
