Question
How can 'Wind power' and 'Biopest control' help to achieve sustainable development?
✓

Answer

  1. Wind Power: Wind is a clean fuel; wind power produces no air or water pollution because no fuel is burned to generate electricity, unlike fossil fuel power sources. Wind power generation produces zero carbon dioxide emissions, which is important with our concern over climate change. Wind energy is also a renewable source of energy, i.e., it does not deplete our natural resources like coal or petroleum based products.
  2. Biopest Control: Biopest control is a natural way of controlling pests that harm plants and crops. It could reduce the use of many pesticides and eliminate the overuse of chemicals. Biopest control is long lasting and inexpensive. Biodiversity would increase too. (This is because of the reduction of chemical applications that often do affect not only the single species they are intended to kill, but other species as well).
