Environmental Catastrophes !

Everyone has heard of the hole in the Ozone Layer and the melting ice caps, but what environmental issues arent being addressed and are widely unknown?
the only one i can think of are nanopollution, microtoxins, and anthropogenic microbial evolution.
are there any more out there ??

Where to begin with?

*Overexploitation of surface and underground water, which have caused disasters in Aral Sea and elsewhere.
*Deforestation, overexploitation and further erosion in tropical and subtropical areas, which lead to lose of soil and desertification in extreme cases.
*Mass killing of living beings by direct and indirect actions: we are in mid of the largest extinction event since dinosaur's collapse. In this case, is human triggered.
*Lose of genetic diversity in crops: this would be a human-natural catastrophe, since the lack of crop's diversity put them in a serious challenge in front of plagues.

I would add the rising acidity of the oceans, oil spills, such as the BP and Mexican spills, evasive species, garbage patches in the oceans, and the list can go on.

Nanopollution? I would say that general macro industrial pollution in areas of the world where environmental laws are laws or aren't [industrial compounds created thanks to our investments, btw] is a great trouble for the biosphere.

Also extinction of species due to human activity is a problematic process. This damages the biodiversity of the biosphere.

True and they don't dissolve. I recycle every scrap of everything I
can put out to be picked up.

Although the extinction of cute, furry creatures garners more attention, the destruction of plant species is just as large a concern. Here in Vermont we have virtually lost the Elm, Butternut, Chestnut, Ginseng plant, and are in the process of losing Ashes, Hemlocks and Beeches. All of these are subject to predation by invasive fungi and insect species (the ginseng has been lost mainly due to over-harvesting in earlier decades).
