This video shows how fishing fleets have depleted the oceans of almost 90% of its big fish; therefore‚ claiming the ocean is not as resilient as it once was.

As shown by the title‚ our earth’s biodiversity is at crisis. But some may wonder‚ what is biodiversity? Wikipedia tells us that biodiversity is the variation of life forms within a given ecosystem‚ biome‚ or on the entire Earth.
