Threats to Coastal Biodiversity

There are many threats confronting our marine bio-diversity. Too much of our inshore water is polluted by sewage, agricultural waste, chemicals and litter. Fishing nets kill some seals and dolphins and a lot of seabirds. However, the most damaging effect of commercial fishing is over-exploitation. Too many fish are being killed, including an increasing number of small fish.

Fish are at the base of the food pyramid that supports everything from a guillemot to a dolphin. There are some disturbing signs that our marine riches are diminishing.
