How could environmental concerns conflict with your desire to improve your stand in living?
Darina [25.2K]

Standard of living refers to the quality, and quantity, of goods and services made available to an individual for his/her consumption. This definition is a general one and is easily understood.

To improve one's standard of living, in accordance with this definition, one needs to be provided with a better quality goods & services , such as advanced electronics and gadgets, or quantity, such as producing more self-care product for consumption.

So how does this conflict with his/her environmental concerns? In order to improve standard of living, there is a few trade offs. To produce more quantity of goods & services, more resources have to be used. This might lead to excessive usage, wastage & depletion of natural resources. For example, to provide more fuel to the society, companies have to extract more & more of fossil fuel. Sustainable usage of natural resources might be a concern, since some types of resources are unrenewable e. g oil & gas.

Production of higher quality products requires advanced state of technology. In the meantime, the use of some technologies aren't exactly environmental friendly i. e it may create pollution. For example, decades ago, manufacturing shirts using traditional methods might not yield consistent results thus the invention of machine helps with increasing the quality, however, results in noise and air pollution. Another example, using air-conditioning instead of hand fan is more effective in coping with hot weather, but greenhouse gas is emitted.

This shows the conflict between environmental concern and the desire to improve standard of living in general.

Hope this helps!

JulijaS [17]

<u>Answer:</u>

<em>Decrease in burning of fossil fuels will affect carbon cycle the most. </em>

<u>Explanation:</u>

Carbon compounds circulate within the biosphere as part of carbon cycle.  In terrestrial ecosystems Plants acquire carbon dioxide through photosynthesis and in aquatic ecosystems plankton absorb carbon dioxide.  

Dead plants bodies deposited underground for a large number of years get converted to fossil fuels and the burning of these fossil fuels releases carbon dioxide into the atmosphere.

Carbon dioxide is also released into the atmosphere through processes like respiration and decomposition of dead organic matter. If burning of fossil fuels is decreased it will be the carbon cycle which will be affected the most.
