Environmental contaminants not only smell and look bad, they also pose a serious threat to human health. Pollutants that resist ecological breakdown can accumulate and contaminate the food chain. When they are consumed by fish and animals, they are in turn passed on to humans, which is detrimental to health.
Chemical pollution is another threat that is harmful to human health as well as to the environment, with a negative impact on the economic well-being of regions affected by it. For example, chemicals can infiltrate sediments and impact large areas of coastal land that depend on a healthy environment for the economic well-being of the region.
Other ways in which humans pollute the environment are by aggressive hunting and fishing, which deplete entire stocks and endanger species. Humans are also responsible for introducing alien products to food chains native to various regions.Learn more about Pollution
