IMPORTANCE OF CONSERVATION OF

NATURAL RESOURCES

FA – 3 BIO. ACTIVITY

NATURAL RESOURCES

Anything in the environment which can be used is called a ‘Natural Resource’. Some our important Natural resources are : Forests and wildlife, water, coal and petroleum.The natural resources are a tool of development (or advancement) for human beings but it should be Sustainable development. The development which meets the current basic human needs and also preserves the resource for the needs of future generations, is called sustainable development.

NECESSITY OF CONSERVING NATURAL RESOURCES

We need to conserve natural resources because there isn't an evidence that these resources are going to last for a long time, considering man's usual consumption of these resources. There will come a time that there are some natural resources that will be gone [especially non-renewable ones and ones that are in high demand] and humans have to thrive in order to find alternative resources for the ones that have been lost. And that specific task is not an easy one because there may be a possibility of unavailability or scarcity of it. Conserving natural resources reduces the rapid depletion of biodiversity and it maintains the balance of the undisrupted ecology. 

Conservation of natural resources is now usually embraced in the broader conception of conserving the earth itself by protecting its capacity for self-renewal. Current thinking also favors the protection of entire ecological regions by the creation of “biosphere reserves”.

MEANNG OF CONSERVATION OF NATURAL RESOURCES

Conservation of natural resources, the wise use of the earth's resources by humanity. The term conservation came into use in the late 19th cent. and referred to the management, mainly for economic reasons, of such valuable natural resources as timber, fish, game, topsoil, pastureland, and minerals, and also to the preservation of forests (see forestry), wildlife (see wildlife refuge), parkland, wilderness, and watershed areas.

YOU CAN MAKE A BIG DIFFERENCE:

It may seem like there is nothing you can do as an individual to stop the factors that are depleting our natural resources. But you can do something. If every person contributed to the conservation of our natural resources and reducing their CO2 emissions footprint, we can make a difference:Reduce carbon dioxide emissions by buying energy efficient appliances.Cycle, walk or use public transportation whenever possible.Save trees by going paperless or by using only recycled products.

WAYS TO CONSERVE NATURAL RESOURCES

Plant a tree wherever you can.Participate in tree conservation projects.Turn of all appliances when not in use.Conserve ElectricityFix leaky faucets and use recycled water for flushing your toilet.Stop polluting the ocean.Harvest rainwater when you can. You can use it for cleaning or watering your plants.

CONSEQUENCES OF DEPLETION OF NATURAL RESOURCES

PRESENT SCENARIO:Are we using up more than what is available?Our current global population is 7.2 billion and growing. (1) Earth’s total resources are only good for 2 billion people at the current demand. Let’s do the math, and it is obvious that the result is a negative.The way we’re living, we are already using 2 to 3 times more of the Earth’s natural resources than what is sustainable. If we do not act now, we will see the consequences of depletion of natural resources – and it’s not going to be pretty. A desolate, dry Earth is not a fun place to live.

OVER EXPLOITATION OF RESOURCES:

OUR NATURAL RESOURCES ARE RUNNING OUT:What are the top 3 natural resources being depleted and what are the consequences?

1. WATER:What will we drink without water?Only 2.5% of the world’s total water volume is fresh water. Of that 2.5%, 70% is frozen.The depletion of our water resources is more serious that the current oil depletion. There are substitutes for oil but nothing can replace our drinking water.70% of the available fresh water that remains in used in agriculture, 20% in industry and only 10% is being used for human consumption. (3)CAUSES: Increased irrigation, increased use in agriculture, roads and infrastructure prevent water seepage in the soil, rising temperaturesCONSEQUENCES: Drinking water shortage. Food Shortage. Famine.

2. OIL:Nothing can be moved, manufactured, transported, built, planted, mined or harvested without the liquid fuels that we get from petroleum.Oil reserves are a non-renewable resource.Oil accounts for 40% of all energy we use.EIA's International Energy Outlook 2013 shows that we have enough Oil to last for 25 years.Efforts are underway to develop cheaper and more sustainable energy such as solar power, wind power and other forms of renewable energy that can replace oil and fossil fuel.CAUSES: Industrial boom, Increased population, Wastage.

3. FORESTS::Imagine a world without trees.An estimated 18 million acres of forests are destroyed each year.Half of the world’s forest has been cleared.Deforestation contributes 12 to 17% of global greenhouse gas emissions annually.Trees absorb greenhouse gases and carbon dioxide.They produce the oxygen we breathe.Forests are the habitats of millions of species.CAUSES: Urbanization, Illegal logging, Agriculture, Subsistence Farming.CONSEQUENCES: Soil erosion, Global Warming caused by the rise of greenhouse gases- Extinction of species and loss of biodiversity. Flooding and drought.

MAIN CAUSE:

If we see the whole scenario, it becomes obvious that the root cause of all

These problems is human overpopulation.

The Earth has enough resources to support only FOUR BILLION people

at present rates of consumption. The Earths population is 7.5 billion now.

All measures to conserve natural resources are meaningless without

controlling population growth.

In the end this is the only measure which can efficiently conserve natural

resources

EXTINCTION OF SPECIESExtinction can be defined as a situation in which a certain kind of species is continuously poached and hunted such that it is no longer available on Earth. Extinction of species can be considered as an important consequence of depletion of resources as if resources get depleted then type of species dependent on that resource would also get depleted along with it. For eg: The passenger pigeon’s traditional habitat was large forests of North America. As settlers cleared the forests for farmland, the pigeons turned to the new fields for subsistence and got extinct.

SOME EXAMPLES OF EXTINCT SPECIES ARE:

PASENGER PIGEON

WEST AFRICAN BLACK RHINOCEROS

QUAGGA

TASMANIAN TIGER
