In the news article " how the world could be running out of fish" it refers back to our older generations and discusses how we use to be hunters and gathers and that now fish are the only wild anmals that we hunt in large numbers.

In Thomson Reuters article “Humans causing catastrophic ecosystem shifts, study finds at least 468 creatures have been eliminated from the planet since 1900”, it is shown that ecosystems have been altered by human dominance like never before. Reuters specifies that the shifts in world ecosystems due to human dominance are unusual compared to the past 500 million years. The radical ecosystem shifts seen are unusual which increases the criticality of the issue.

In the article “ Resource depletion: Opportunity or looming catastrophe? ”, Richard Anderson, a news reporter at BBC, argues that an accelerated global population growth cannot be sustained with the present models of production in a world with finite resources. The current world population is around 6 billion and is predicted to increase up to 9 billion by 2050. Anderson based himself on McKinsey Global Institute to explain that the vast majority of the new population will be part of the middle class consumers, thus the demands in food and products will be very high.
