How can we stop overfishing?
Logging and collecting Similar cases of overharvested species are found in terrestrial ecosystems. For example, even when forests are not completely cleared, particularly valuable trees such as mahogany may be selectively logged from an area, eliminating both the tree species and all the animals that depend on it.
Why do we need to reduce overharvesting of the earth's resources?
Overharvesting, or overfishing in the case of fish and marine invertebrates, depletes some species to very low numbers and drives others to extinction. In practical terms, it reduces valuable living resources to such low levels that their exploitation is no longer sustainable.

When the fish stock number decrease rapidly, some species can become endangered because#N#they can’t replenish their populations. Some species lose their preys and unable to survive. Before the whole populations underwater end up being histories in the encyclopedia, it’s very crucial to protect the endangered species to save them from the extinction. However, how does the protection can prevent the overfishing? The conservation status of a species depends on the number left in nature. If the fish species are under the control, their numbers are always being observed. So, if there is any change in their number, it will be easier to spot it. There will be no opportunity for the overfishing because the fish stock numbers are always under the observation.
