In the article, "Condition Critical:An exclusive look at a U.N. assessment of
Earth's ecosystems shows they are strained to the limit," the author Eugene Linden begins

can support which will eventually put a good number of fisheries out of business.In the
past thirty years, global economies have increased food output and livestock production
but have depleted and polluted water supplies, ruined the soil and destroyed habitats.
