Factory pollution affects the ecosystem in different ways. The ozone layer is greatly affected. Factory pollution adds to global warming, the ground-level ozone is detrimental to human health by causing or worsening respiratory problems. It negatively impacts ecosystems by damaging vegetation. Each year the ozone causes $500 million worth of reduced crops.
Taking really long showers is harmful to the environment because you are using more energy, which means more fossil fuels need to be burned, which means you will release more CO2. This causes global warming. Using water means it will need to go to a wastewater treatment plant to be cleaned. This also requires energy, and the treatment may not be perfect, which means some of the contaminants in the shower water (soap, etc.) may end up in the environment.
