Why are reefs important to the fishing industry?
Reefs are very important to the fishing industry because they are the natural habitat of the bait fish which is used to fish for tuna and other large species.

What are rivers used for?
Rivers provide travel routes for exploration, commerce and recreation. River valleys and plains provide fertile soils. Farmers in dry regions irrigate their crop-land using water carried by irrigation ditches from nearby rivers. Rivers are an important energy source.
Wetlands protect our shores from floods by reducing the impact,they also absorb pollutants and they also improve the water quality.And lastly the provide a habitat for many different types of animals and plants.

How can we protect the wetlands?
We can help the wetlands lands by stop throwing polluted water and garbage into the wetlands.We can also help by controlling the use of pesticides because pesticides are a major issue in wetlands because they get into the plant and then travel it's way up and then make it to the last part of the food chain and then kills whatever species it gets into. And that can lead into biodiversity lost.

They are so important because they provide homes for many different types of species of animals in the oceans.The coral reef protect them from predators.They also protect the coastlines from damaging waves.
