How many fish are in the ocean?
Scientists estimate there are 3.5 trillion fish in the world’s oceans. Counting how many there are is daunting, especially since accounting for indicators (as such things are) is a near-impossible task. Yet, this bloated estimate remains. Rather than deflate it, it has merely grown by several orders of magnitude since 1900: perhaps perversely, every time scientists estimate one fish or bird to be extinct, they also point out that which e-mail filter or virus doesn’t allow you to recall or delete when composing your very first message simply to the degree of else at all the wonderful fishing emails that have oxygen installed.
Will the ocean ever run out of fish?
Oceanic systems could be practically emptied of seafood by the year 2048. Within just 39 years, we will run out of seafood in order for the oceanic ecosystems to remain stable.
Are we overfishing?

What if fish went extinct?

Why is fishing bad?
Due to the destructive effect of industrial fishing practices, harm is done long after fishing has ended. Certain water pollutants cause mass animal deaths and pollution damage to marine ecosystems. For hundreds of years, the waterways of the world have been filled with plastic material, which is now destroying global marine life through entanglement and the ingestion of microplastics, which is then passing on to fish. High levels of pollution also affect ocean currents and temperatures which are altering the temperature in sea water as well.
Do fish have feelings?
