Which is a sustainable practice? Operating wind farms clear cutting flood irrigation overfishing

Option A) Operating wind farms

Option B) Clear cutting

Option C) Flood irrigation

Option D) Overfishing

Answer:- Option A) Operating wind farms


Operating wind farms is generally considered a sustainable practice for several reasons:

  1. Renewable Energy: Wind turbines generate electricity from the wind, which is a renewable resource. Unlike fossil fuels, wind energy is not a finite resource, meaning it will not run out.
  2. Low Carbon Emissions: Wind energy produces very low carbon emissions. The only emissions associated with wind energy come from the manufacturing, transportation, and installation of wind turbines. Once a wind turbine is up and running, it produces zero carbon emissions.
  3. Energy Security: Wind energy provides a source of energy that is independent of fossil fuel supplies. This makes countries less dependent on imported energy and more energy secure.
  4. Cost-Effective: The cost of wind energy has decreased significantly in recent years, making it increasingly cost-competitive with fossil fuels. This means that wind energy can provide electricity at a similar cost to fossil fuels, while also being more sustainable.

In contrast, clear cutting, flood irrigation, and overfishing are all practices that can have negative impacts on ecosystems, such as deforestation, water waste, and depletion of fish populations, respectively. Therefore, it is important to prioritize sustainable practices that have minimal impact on the environment and can help preserve natural resources for future generations.


Refers to the practice of cutting down all or almost all of the trees in a particular area of forest, typically for commercial purposes such as timber harvesting or agriculture.

Flood irrigation:

Flood irrigation can be detrimental as it leads to excessive water usage, soil degradation, and depletion of groundwater resources.


This can lead to the depletion of fish populations in oceans, rivers, and other bodies of water. Overfishing occurs when fish are caught at a rate faster than their natural reproduction rate, leading to a decline in their numbers over time. This can have significant ecological and economic consequences.

Overall, operating wind farms can help to reduce greenhouse gas emissions, increase energy security, and provide a cost-effective source of renewable energy. This makes it a sustainable practice that can help to address climate change and promote a more sustainable future.
