Natural resources :

“How to combat waste?

Class 3F - 4th grade

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?

RENEWABLE …

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.

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)

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.

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.

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.

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.

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.

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.

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.
