To recap:


Aerosol pollution: small particles in a suspending medium causing havoc with both planet and people.


Air pollution: a look at the atmospheric nasties largely created through man's activities.


Biodiversity loss: a shocking wake-up call to arms to stop the relentless devastation on the planet's co-inhabitants.


Deforestation: a worrying onslaught against a resource that provides shelter, food, oxygen, biodiversity....the list goes on.


Global warming: the subject that won't go away. The evidence is mounting and global temperatures keep rising.


Groundwater depletion: groundwater is the most valuable freshwater resource on Earth but demand exceeds supply.


Human overpopulation: the 'elephant in the room' subject. Whilst mankind pushes science and technology to deliver an ever-increasing quality of life and to extend life expectancy, it simply puts ever-increasing demands on the planet's resources.


Land degradation: so important for biodiversity and food supply, land availability and quality are both being hammered by human activity.


Nitrogen pollution: as so often is the case, scientific discovery aimed at creating good, ends up creating serious unintended consequences.


Ocean acidification: an unforeseen consequence of human activity.


Ozone layer depletion: a horror story with a possible happy-ending and proof that global action can make a difference.


Plastic pollution: a case study in how human activity can wreak global havoc in the blink of an eye.
