  • Eco-friendly means earth-friendly or not harmful to the environment.
  • The car uses petrol or diesel that is non-renewable. So it is not eco friendly
  • Polybags are non-biodegradable. It is also not eco friendly
  • Dyes are synthetic chemical compounds so not eco friendly
  • The wind is a renewable source of energy. So, using windmills to generate power for irrigation is an eco-friendly activity.
