Human industrial activities, production, and by-products of globalization as a result of human development provide negative local and global impact on the marine environment. Thus, human-generated materials interact with the marine environment, they include persistent organic pollutants, polycyclic aromatic hydrocarbons, brominated flame-retardants, organometals, and numerous pesticides (Crain, 2009, 40). Globally, they negatively impact the coastal marine environment; industrialization results in pollution from toxins or fertilizers, overharvesting, and disease. Unfortunately, habitat loss entails the complete removal of the ecosystem and its services (Crain, 2009, 40). On the other hand, the conversion of a system to a different habitat type will result in restoration to convert back to its original state or will be permanent. Locally, human-generated materials interact with certain species that are usual for certain environment (Crain et.al., 2009, 41). The main idea is that human development poses a threat to the marine environment.
The effects of human activities on the marine environment are very dangerous. Thus, human development affects oceans, impact the introduction of marine pests, and harvesting sea foods (The effects of human impacts on the marine environment n.d.). The first thing is that most of the animals in the sea eat only fish and need it for survival. Fishing techniques often negatively impact seascapes and habitats (The effects of human impacts on the marine environment n.d.). Next, activities that people do in the sea impact land because pesticides and herbicides are washed out to seas (Crain, 2009, 41). Thirdly, some marine species can be introduced from other parts of the world, which may pose a threat to other species and reduce populations of local species (The effects of human impacts on the marine environment n.d.). In other words, all these effects of human impacts on the marine environment pose a risk to the ocean environment.
