Pollution is the introduction of contaminants into an environment that causes adverse effects on either the environment or humans. In 2015, pollution killed 9 million people worldwide.[1]
As with many other social issues, pollution arises out of a specific mode of production. For example, air pollution increases if a society chooses to orient itself towards personal internal combustion vehicles rather than high speed rail, which emits significantly less pollution on a per-passenger-mile basis.[2]
