First of all we must have
a better understanding about what is meant by depletion of natural resources.
Depletion of natural resources means the exhaustion of raw materials within a region.
Resources, such as forests, fish, fossil fuels,
and healthy soils are rapidly being depleted, and these valuable gifts of
nature are in danger of vanishing from the planet. There are many reasons for this
resource depletion. They are;
- Over-consumption or unnecessary use of resources
- Non-equitable distribution of resources
- Deforestation
- Overpopulation
- Technological and industrial development
- Mining for oil and minerals
- Aquifer depletion
- Pollution
Let’s Talk About Some Main Reasons
Overconsumption and over population
Natural
resources in the form of materials, water and energy, as well as the land
available to us on Earth, are the basis of all living beings on our planet. Without the constant use of natural
resources, neither our economy nor our society could function.
Humankind has consumed more natural resources over the past century than
over all earlier centuries put together. As human populations continue to grow
to over 6.7 billion, the rates of consumption and waste are increasing rapidly.
As populations grow more rapidly, more people are forced to compete for
resources. Resources have been worn
away because of people’s greed. Increased wealth has spurred the demand for
resources, like luxury foods. Humans in arid, populous regions, like the Middle
East, demand more fresh water, which is endangering freshwater environments and
species. In less developed countries, like some African countries, surprisingly
more water is wasted and pollution is less carefully controlled than in more
developed countries. People all over the world have been forced to focus more
attention on consumption of resources and moving beyond individual action. In
years to come, people may no longer have the luxury they have today.
Furthermore…………..
The earth does
not contain enough resources to indefinitely sustain the current enormous
population growth. For instance, there is a limited area of arable land and
living space.China, home to 1.2 billion people or 1/5 the
world's population, is an excellent example of the kinds of problems that arise
in an increasingly crowded society.
In many areas,
there is simply not enough food to feed the growing populations. Each day
40,000 children die from malnutrition and its related diseases. 150 million
children in the world suffer from poor health due to food shortages.
Another resource, which cannot keep up with an increasing population, is water. The supply of fresh water is limited. Due to this limitation many problems can be occurred. Also the Creating fresh water can be expensive. A swelling population may have to turn to desalinization for their clean water. Oil-rich Saudi Arabia is the only country for which this process has had any success. However, Saudi Arabia does not require the vast amounts of agricultural water that California and other areas need. Another possible solution to the fresh water shortage is towing icebergs from the polar caps. This is just too costly for many areas.
With the
overpopulation the depletion of natural resources are getting increased,
because the need of resources for their survival are also increased.
Birth control and
family planning is the most suitable method for overpopulation……
Deforestation
- The term deforestation refers to the clearing of natural forests by logging or burning of trees and plants in a forested area.
- Presently one half the forests on earth have been destroyed as a result of deforestation……….
Causes:
- · Logging (both legal and illegal)
- · Industrialization
- · Agriculture
- · Oil exploitation
- · Human disasters
Effects:
Because deforestation is so extensive, it has made several
significant impacts on the environment,
v
Global warming: Because trees and plants remove carbon dioxide and emit
oxygen into the atmosphere, the reduction of forests contributes to about 12% of
carbon dioxide emissions.
v Decline in Wood: Deforestation causes a dramatic
decline in the wood that satisfies industrial, fuel, and other human needs.
v Water Conditions: Deforestation plays a role in the
amount of water found in the soil, as well as the level of moisture in the
atmosphere
v Precipitation: The loss of vital trees and plants affect the water cycle in many
different ways, as the absence of litter, stems, and trunks of trees all play
an important role. With less forest covering the land, the ability to
‘intercept, retain, and transport precipitation’ is affected. When
precipitation is not trapped, surface water transport occurs at a faster rate.
Possible outcomes include flash floods.
How to prevent
deforestation
a) Use Recycled Items:
Today, a consumer can purchase a
variety of recycled items, including notebook paper, books, toilet paper, and
shopping bags. When people use recycled products and make a conscious effort
not to waste, the demand for new raw material to replace these items can
decrease.
b) Tree Care:
When cutting down trees “single out full-grown specimens and
spare younger varieties. In the event that you must remove a tree for a
legitimate reason (for safety issues or power line interference), make sure
that for every tree lost “another is planted in its place.
c) Farming Practices:
Those who plant crops at a farm
can participate in putting a dent in deforestation by rotating crops. It is
suggested to replace the habit of using different portions of land each year
with using the same portion of land to plant different crops. This practice has
proven effective in maintaining soil fertility. Farmers may also embrace many other options,
such as high-yield hybrid crops and hydroponics, which relies on a method of
growing plants using mineral nutrient solutions instead of soil.
f) Reforestation
g) Support Conservation Organizations:
Lend
your support through donations of your time, money, or actions to organizations
that run programs concentrating on the preservation of forest habitats, such as
Greenpeace, World Wide Fund for Nature, Community Forestry International, and
Conservation International.
