Vehicular emissions are responsible for 70% of the country’s air pollution. * Bharat stage 1 to 4 emission norms are emission standards that focus on regulating pollutants released by automobiles. Most sulphur dioxide comes from power plants that use coal as their fuel. Automobiles produce about half of the nitrogen oxide. When wood‚ household garbage‚ plastic‚ or leaves are burned‚ they produce smoke and release toxic gases. The smoke contains vapors and solid compounds suspended in the air called

means their stock is maintained at a certain level without depletion. Also‚ by refusing to work with the fur of wild and endangered animals we strive to sustain their population and save the places of their natural habitat. This means that our manufacturing process mitigates any possible environmental damage. The production of artificial fur is much less eco-friendly. Manufacturing requires the use of synthetics materials produced out of coal‚ limestone and petroleum. These resources are no-renewable;
