How does soil pollution affect the food chain?
The pollution of water and soil may or may not affect us directly, but that doesn’t mean it doesn’t affect us at all. In either case, it disrupts the food chain. While the toxic chemicals dumped in water are ingested by fish, contaminants in the soil are absorbed by plants along with nutrients after they get dissolved in water. In this manner, the concentration of chemicals in the food chain increases as they are transferred from one trophic level to the other in what is known as biomagnification. The same chemicals are eventually transferred to us when we feed on plants and animals.

How has environmental politics influenced the development of environmental governance?
The development of environmental governance, along with technological progress, has initiated the deployment of a dialogue. Environmental politics has created objections and points of opposition between different political parties, scientists, media, and governmental and non-governmental organizations (22). Radical environmental activism actions and movements have been created (22). The rise of the new information and communication technologies (ICTs) are many times examined as to whether and in which way they have influenced means of communication and social movements such as activism (28). Since the 1990s, the term “digital activism” has been used increasingly and in many different disciplines (29). Nowadays, multiple digital technologies can be used to produce a digital activism outcome on environmental issues. More specifically, devices with online capabilities such as computers or mobile phones are being used as a way to pursue change in political and social affairs (30).
