Sewage is wastewater that contains a mixture of human waste, food scraps, chemicals, and other pollutants, typically generated from households and industries. It can be harmful to humans by contaminating drinking water sources, leading to waterborne diseases like cholera and dysentery. Additionally, untreated sewage can damage ecosystems, harm aquatic life, and contribute to the spread of pathogens and harmful chemicals in the environment. Proper treatment and management of sewage are essential to mitigate these health and environmental risks.
Physical and chemical changes are harmful to us.
Renewable energy is not really harmful in any way. When it is turned into electricity it can kill you, like all electricity.

See "What does the ozone layer do?"
Wind is harmful because it can destroy a building and blow someone away at the right speed. On the other hand, it's helpful as it provides us with a source of energy.
Simply because it has lots of bacteria.
bacteria and dirty toilet paper the bacteria gets filtered and cleaned to make sure there is no harmful bacteria in the water and the toilet paper dissolves on its way to the sewage water treatment facility
There is usually a law against running sewage line just into the woods. The raw sewage that comes out into the woods could possible be harmful to animals and humans.
Sewage pipes can be harmful to soil if they leak or break, releasing untreated wastewater and chemicals into the soil. This can lead to contamination of the soil and groundwater, affecting plant growth and biodiversity. Additionally, sewage pipes can introduce pathogens and pollutants into the soil, posing a health risk to humans and wildlife.

Oil kills animals, plants and more. It can leak into rivers and sewage. Like the Yangtze River
don't know at all but i do know 1 thing and that is the poo and wee is made into a liquid
Some technologies, such as changing sewage in to useable gas, produces CO2 as part of the process.
Ozone affects us in positive way. it protects us from the harmful UV radiations of the sun.
Sewage can release methane and nitrous oxide, both potent greenhouse gases, into the atmosphere through anaerobic decomposition. Additionally, when sewage is not properly treated, it can lead to the release of harmful pollutants such as sulfur dioxide and ammonia into the air, contributing to air pollution.
Sewage can deplete oxygen levels in rivers as bacteria breakdown the waste, causing fish suffocation. It can also introduce harmful chemicals and pathogens into the water, leading to fish mortality. Additionally, sewage can disrupt the natural balance of the ecosystem, impacting fish health and survival.
Some common separation techniques used in treating sewage include sedimentation, filtration, biological treatment, and disinfection. Sedimentation is used to separate solid particles from liquid sewage, filtration involves passing sewage through a medium to remove impurities, biological treatment uses microorganisms to break down organic matter, and disinfection kills harmful pathogens in the treated sewage.
