Reusing definitely helps us and the environment in several different ways. Reusing helps prevent pollution by lowering the amount of raw materials being made. This in turn lowers the amount of energy being used which lowers the amount of greenhouse gas emissions. This helps the environment by bringing down Earth's average surface temperature. Reusing also reduces the amount of waste going to landfills. Landfills have toxic chemicals  which contaminates the water around them, which is harmful to people's health and the environment. This is why reusing materials and reducing the amount of waste going to landfills helps us and the environment.
