It may decrease the fertility of the soil or destroy the land completely that can make it unable to be planted by crops. Lastly, water pollution refers to the contaminants found in water surfaces that can also threaten marine biodiversity and decreases the food source of the world....
1. Given two sources of air pollution, what is the cost-effective means of controlling pollution? How is this different from the efficient level of pollution? 2. Compare and contrast the three means o Explain what is meant by an externality and describe what policies could be used to achieve...
We tend to think of air pollution as something that happens outside—but that's not always the case. Even inside your home, there are things like dust mites and dirt trodden in from outdoors to worry about. Indoor air pollution from sources like this can irritate your lungs and contribute...
