SEAGRASSES AND MANGROVES
 |

They are an ancient species of flowering plants that grow
submerged in all of the world's oceans. Seagrasses link offshore coral reefs
with coastal mangrove forests. Today, these "prairies of the sea," along with
mangroves, are on the decline globally. Scientists fear the diminishing
vegetation could result in an ecosystem collapse from the bottom of the food
chain all the way to the top. Changing Seas joins experts in the field as they
work to restore Florida's important mangroves and seagrasses.
Known as
"hotspots of biodiversity," seagrasses and mangroves attract and support a
variety of marine life. However, worldwide damage and removal of these plants
continue at a rapid pace. Changing Seas travels along Florida's coastline to get
a better understanding of the significant roles mangroves and seagrass play
within the state. Can biologists prevent a negative ripple-effect throughout the
marine food web before it's too late? How will rising sea levels impact these
plants as well at the communities that depend on them?

HUMAN GEOTRASHING: 2750 CONTAMINATED SITES IN THE ARCTIC

No place on Earth escapes the impact of human activities. Not even the frozen poles.
We humans have become geotrashing agents.
As geotrashing agents, bluntly speaking, we have fucked up Earth. We have turned this planet into a waste dump.
Let us take the Arctic, for example.

As geotrashing agents, bluntly speaking, we have fucked up Earth. We have turned this planet into a waste dump.
Let us take the Arctic, for example.
Bois (2009) has reported a total of 2750 contaminated sites (Table 1) where humans have dumped different types of pollutants (Table 2) in the Arctic alone.

Table 2. Inventory of pollutants in the Arctic. Data from Bois (2009).
POPs = Persistant organic pollutants; PCBs = Polychlorinated biphenyls; n/a = not available.
Obviously, Bois (2009) has done an excellent job investigating and recording the contaminated sites in the Arctic. It is a must to read.
Unfortunately this is not the end of man´s geotrashing line.
Things in the Arctic are bound to become even worse.
Man´s geostrategic games are already changing in the North with the melting icecaps due to man-made global warming.
Thus, there is a rush for the Arctic.
Faced with an ever increasing mass of consumers always demanding new products in the global markets, oil and mineral companies will do their best to get the new resources to satisfy unsatisfiable customers.
For the time being and at a time when we are running out of time, it seems that our goal still is nothing but to make this beautiful planet a barren land.
How fucking stupid can Homo sapiens be?
Only time wil tell.

GLOBAL WARMING: END OF THE LINE
 |
| Source: BLAZINGCATFUR. |
“You do not repair
the climate of an entire planet without staggering sacrifices unless the burden
is shared with something like parity. To put that as succinctly as possible,
the days of paradise for a few are drawing to a close. The game of finding someone
else in some convenient misery to fight our wars, pull our rickshaws, and serve
as the offset for our every filthy indulgence is just about up. It is either
Earth for all of us or hell for most of us.”
Garret
Keizer
