Growing Crops

Countries that are highly dependent on non-vegetarian diets need much larger areas for pastureland than those where the people are mainly vegetarian.

True

Our natural resources can be compared with money in bank. If we use it rapidly the capital will be reduced to zero. On the other hand if we use only the interest, it can sustain us over the longer term.

Sustainable Utilization or Development

Are indicators of the sustainable use of resources.

Quality of Human Life, Quality of Ecosystems on Earth

The natural reserves which man utilizes for sustenance and welfare.

Stock Supply

A biotic community predominant of trees, shrubs or any other woody vegetation usually in a closed canopy.

Forest

Commercial Uses, Wood

Many of the plants are utilized in preparing medicines and drugs; Total worth of which is estimated to be more than $... billion per year.

Commercial Uses, 300

Many ... are used for mining, agriculture, grazing, and recreation and for development of dams.

Commercial Uses, Forests Lands

The main greenhouse gas carbon dioxide is absorbed by the forests as a raw material for photosynthesis.

Production of Oxygen

The main greenhouse gas ... is absorbed by the forests as a raw material for photosynthesis.

Carbon Dioxide

Acts as a sink for carbon dioxide thereby reducing the problem of global warming caused by greenhouse gas CO2.

Forest Canopy

Forests are the homes of millions of wild animals and plants.

Wild Life Habitat

Are the homes of millions of wild animals and plants.

Forests

About ... species are found in the tropical forests alone.

7 million

Act like giant sponges, absorbing the rainfall, slowing down the runoff.

Forested Watersheds

They control climate through transpiration of water and seed clouding.

Forested Watersheds

Forests bind the soil particles tightly in their roots and prevent soil erosion.

Soil Conservation

Forests also act as wind breakers.

Soil Conservation

Forests can absorb many toxic gases and can help in keeping the air pure and in preventing noise pollution.

Pollution Moderators

Man depends heavily on forests for food, medicine, shelter, wood and fuel.

Over Exploitation of Forests

With growing civilization, the demands for raw material like timber, pulp, minerals, fuel wood etc. shot up resulting in large scale logging, mining, road-building and clearing of forests.

Over Exploitation of Forests

Ecological Significance of Forests

Regulates earth temperature and hydrological cycle.

Ecological Significance of Forests

Encourage seepage and reduces runoff losses, prevents drought.

Ecological Significance of Forests

Reduces soil erosion (roots binding), prevents siltation and landslides thereby floods.

Ecological Significance of Forests

Litter helps in maintaining soil fertility.

Ecological Significance of Forests

Safe habitat for birds, wild animals and organisms against wind, solar radiation and rain.

Ecological Significance of Forests

Refers to the loss of forest cover.

Deforestation

Land that is permanently converted from forest to agricultural land, golf courses, cattle pasture, home, lakes or desert.

Deforestation

Tropical Deforestation, FAO of UN

Depletion of forest tree crown cover less than 90%.

Forest Degradation

FAO

Food and Agriculture Organization

Conversion of forests to agricultural land to feed growing numbers of people.

Agriculture

Destroys

Commercial Logging

Raising cash crops for increased economy.

Cash Crop Economy

The needs also increase and utilize forests resources.

Increase in Population

Conservation derived from two Latin words, ...- together ... - to keep or guard measures, i.e. an act of preservation or to keep together
