From boxes to milk cartons, you can fight pollution by recycling those everyday household items. Recycling is less energy-intensive, said Anca Novacovici, founder of Eco-Coach, a Washington, D.C.-based environmental sustainability advisory firm. For example, when paper is recycled, the production and pollution from paper plants decreases. “Since most energy in the U.S. is from polluting fossil fuels, less energy consumption equals less air and water pollution,” said Novacovici.
