Long-term ecological impacts of oil spill in gulf of mexico. Human pressure on littoral zones: shoreline modification, garbage, nutrients, chemicals, oil spills, overfishing, atmosphere carbon concentrations are altering ocean chemistry, global warming is altering sea surface temperatures. Why worry: transition zone between ecosystems, extremely sensitive environments; high level of biodiversity, so many of us live there and our health/well being is dependent on them. Collapse: when humans: consumer more resources than the environment can provide. Required reading: render the environment toxic .
