Sustainable Resource Use?

Question

What is sustainable resource use?



Put A, B,C,D or E or combination of the sentences which you agree with.

A) Resources which increase by modest use?
Such as animals grazing which promotes further growth of the plant at the right height for grazing?

B) Resources unaffected by use
The diversion of part of a river to irrigation the water is returned to the stream after use is also unaffected after use.

C) Resources which disappear or degrade if not used.
An unharvested crop of an annual plant.

D) Resources that are reduced by use
Fish, clay deposits, coal and oil

E) Those which pollute or destroy other resources
Residual poisons, sewers running pollutants into the sea, large areas of concrete.

Wow Byderule I just wanted you to type A B C D or E that simple. Love the book though LOL.

Answer 1

I hate this A and B questions
cant i just answer what resource is ¿

E
is obviously gross mis management of resource.that cuts drastically into any concept of sustainability and is very costly to rectify
with a whole range of negative effects thrown in.

D
fish do not have to be a reduced resource if one is in to Aqua culture and breed and manage fish populations ,with disciplined or controlled harvesting
The others are used up but clay only changes location
it is still around if it becomes pots or is used to line dams

C
depends on what actions one takes ,if plowed into the land it adds to soil quality and so the energy is merely transferred .the crop becoming compost
or one can set the cows into it and save on forage,the unharvested crop turning into meat ,and the cow manure adding to soil quality.

B
diverted rivers if enough farmers do it certainly affect the river flows so much so ,that a river can become dry part of the year .
depending on the location and size of the rivers
in Europe these actions are less noticeable because the rivers are so big
But in Africa and Mexico (which I can talk about )this is very much visible ,And diverted waters for irrigation have dried up huge areas changing and killing animal habitats .

granted the irrigation sinks in to the soil ,and with time returns to subterranean water supplies that are part of the systems that feed the rivers ,but much (especially in modern farming ,because they do not MULCH)
is evaporated and leaves the locality
by way of the air,and does not return to the river the river .

So to have this as a sustainable situation additional measures are needed such as water harvesting diverting the falling rain waters before it reaches the rivers into the ground by way of ditches and dams

finally A
controlled grazing a nice idea that almost never happens in practice ,in third world countries many deserts are created by over grazing
every where ,especially cows, are left to them selves .on the lands ,

Only in northern Europe are pastures that rich
that cows can graze with out damage and are moved in time to give the pastures rest ,

But go look at Texas or Mexico one cow to a couple of hectares nibbling to the ground any thing they find in the dry soil.

Besides cows and other domestic grazers like goats or sheep don`t read books on
pasture behavior ,the must be managed by vigilant herdsmen.this tends not to happen

Funnily it happens the most in rural Africa, where boys ,herd the domestic animals , from one grazing spot to the next,

The same happens in rural Mexico
this part of the question is very difficult to answer because there is so much variation depending on location.

In South Africa the northern parts are abandoned cattle farms because the heavy feet of the cows ,and their over grazing has turned the country into semi desert.

So A is a concept that in reality can apply to mostly Northern Europe
The best way to treat pasture is what they do in Holland it is called zero grazing ,the cattle are stabled ,the grass is cut and brought to them ,and their manure and urine is returned to the pasture,the closest we can come to sustainable
pasture use ,
because when the cattle walk on iot their heavy feet compact the soil and raise the salt to the surface,

NOTE ,

the best example ever ,of sustainable grazing or land use for animals , to the fullest has never been employed ,
people are so clever .

And that was the African veld or prairies ,these places were jam packed with many hundreds of species of animals and grasses ,an immense treasure of meat ,and the food needed to sustain the production with a quality and disease control build in ,in the form of predators .

All we needed to do ,was to protect it and cull the males for the market.
how ever a change of diet was called for (this is difficult with humans who insist on their preferences)
So man in his wisdom killed the animals ,changed the flora ,added cows and destroyed the place with in a 100 years
this was one location of south Africa`s desertification

So when we talk about sustainability ,In the beginning Nature still is the mother of all sustainabilities.

I hope i have answered some of your question
not sure if i really understood it

Answer 2

love is not an emotion, it is a capability and some people, never know love, so no. People in love still have to work everyday with their partner to stay in love and look past the small quirky things the other person does. Love for a child is dependent on who you are. Giving birth doesnt automatically mean love that child, (being honest) (e.g. crackhead mothers, emotionally handicapped individuals) it depends on so many external and internal factors. Love is not sustainable if it was never attainable.

Answer 3

the best thing we can do is going back to a smaller scale of all and more diversity. But we will make money so we will never reach anything
