explain how improvements in technology have led to overfishing and the depletion of fish stocks in the oceans, HAS TO BE A PARAGRAPH LONG

I divided them in paragraphs to make it easier...

Overfishing is one among many environmental problems that scientists expect to be exacerbated by climate change. A new study by the Institute of Environmental Science and Technology published confirms that climate change poses a major threat for the global fishery, but shows that the continual improvement of fishing technology could pose an even greater threat.

Scientific study of large-scale environmental problems, such as global fishery, is often divided between the natural scientists, who study the physical, chemical, or biological aspects, and social scientists, who study the human dimension. The new study includes both natural and social aspects, interacting together over time, connected within the structure of a general circulation model. This allowed the authors to calculate how climatic, economic, and technological factors add up at the global scale, when viewed over many decades.
