Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

The Eight Steps that Help Kill More of Our Fish

How Your Car’s Exhaust Emissions Helps Create Dead Zones and Kill Our Fish

Step One: You fill up the tank (gasoline is a processed fossil fuel product).

Step Two: As you drive around, your car burns the fossil fuel and produces greenhouse gases and other harmful pollutants, which are spewed out through the exhaust pipe.

Step three: Sunlight interacts with greenhouse gases emitted from your car, producing ground-level ozone.


Only about 12.6 percent of the gas your car consumes is used for driving!


Step Four: High ozone levels damage crops such as corn, wheat, and soybeans, reducing growth rates and crop yields, as well as making the crops less resistant to insects and pests. (In 1995, ground-level ozone caused $2.7 billion in crop damage nationwide, according to the U.S. Environmental Protection Agency.) Current estimates for the crop damages caused by ground-level ozone stand at about $3 billion each year in the US alone.

Step Five: To increase growth rates, boost crop yields and fight pests, farmer use increasingly larger amounts of chemical fertilizers and pesticides.

Step Six: Nutrient-rich chemical runoffs (pollution) from agricultural fields are washed by rain into streams, storm sewers and rivers and end up into our oceans, seas and other water bodies.


Summer rains wash nutrients, dissolved organic matter and sediment out of the mouths of rivers, into the sea, sparking large phytoplankton blooms. South America presents two excellent examples of river outlets where phytoplankton tends to thrive. Along the northern part of the continent the mouth of the Orinoco River opens into the Caribbean.

Step Seven: Dead Zones that cover tens of thousands of square kilometers of waterways are created by pollution-fed algae, which deprive fish and other marine life of oxygen.

Step Eight: Deprived of oxygen, fish and other marine life die.


Dead fish are seen on a basket of a fish farm off a coast of Menidi village in the Amvrakikos Gulf, some 350Km northeast of Athens February 28, 2008. Local marine biologist Vangelis Dimitriou said that up to 800 tonnes of fish including sea bass and sea bream died from a lack of oxygen [hypoxia], after swimming through a large pocket of water where the temperatures suddenly dropped at a drastic rate.

But it doesn’t have to be that way!
