How does dumping waste affect the environment?

Disposing of waste has huge environmental impacts and can cause serious problems. … Some waste will eventually rot, but not all, and in the process it may smell, or generate methane gas, which is explosive and contributes to the greenhouse effect. Leachate produced as waste decomposes may cause pollution.

What are the disadvantages and advantages of water pollution?

Water pollution damages the environment, so it needs to be controlled because it can cause diseases, it can affect soil, it affects animals that live in water, and clean water is also essential to our survival. Polluted water can be the cause of various diseases.

Which waste is most harmful for marine life?

Oil spills can have devastating effects. While being toxic to marine life, polycyclic aromatic hydrocarbons (PAHs), found in crude oil, are very difficult to clean up, and last for years in the sediment and marine environment. Oil spills are probably the most emotive of marine pollution events.
