Some useful info to digest over Sunday dinner

29% of Earth is land mass. Of that 29% humans occupy less than 1% of that area. Of the remaining 28% about 40% is pure wilderness. 14% is true desert and 15% has desert like characteristics. 9% is Antarctica. Most of the remaining 22% are agricultural areas. There may be other areas with a human footprint of some kind but it is insignificant in any relation to global warming.


What percentage of the earth is land?
By the most common criteria used (which includes swamps and seasonal dry land), the Earth has a land surface of 144,940,000 km2, which is about 29.2% of the total surface area of the planet.

How much space do cities take up of inhabited land of earth;

Urban areas (1.5%) (148,940,000 km2 land) =2,234,100 km2 Urban areas -------------------- Earth Surface area 510,072,000 km2

Hi Land Shark; Re: "You've not covered 0.001% of species extinct. ";

Life has existed on this planet for something like 500 million years. At any given time there's perhaps a million species and, on average, one goes extinct every year. So, back of the envelope, there are something around a half billion extinct species. Big deal. Name me one that was made extinct by man-made CO2.

Re: "I suggest you start here for more complete lists:";

I went through *all* the mammals that have been declared extinct in the last 20 years. I found zero were made extinct by man-made CO2. You're the one that is claiming that climate change is making species extinct.

So name one. You've got a "more complete list" to begin with.

--------------------------------------------------------------------------------------------------------------

As with other lefty emotional ideas, you really haven't thought this one through.

Suppose mankind decides that CO2 is really bad and decides to quit using fossil fuels. Where is the energy going to come from?

Here's a hint. The biggest thing that industry does to make species go extinct is the elimination of their natural habitat. Suppose we start growing hemp for cellulosic ethanol. We will be taking unused (marginal) farm land that is currently supporting diverse species and turning it into factory farms for hemp. What's that going to do to habitat? Why do you think the environmentalists reversed themselves on ethanol? It's because the program took a lot of fallow land and turned it into factory farms.

Already wind farms are making a dent in the California golden eagle population. Environmentalists are opposing the use of desert for solar power because of the resulting habitat loss.

Your program to reduce fossil fuels is turning the world into an industrial waste of factory farms (with the inevitable pesticide, herbicide and fertilizer use), industrial wind farms and solar collectors.

Hi Land Shark; About those species going extinct; the dirty side of clean energy:



Golden Gate Audubon is committed to reducing the levels of bird mortality at Altamont Pass to the greatest degree possible. In early 2004, Golden Gate Audubon joined the Center for Biological Diversity and Californians for Renewable Energy in a formal appeal to the Alameda County Board of Supervisors challenging the renewal of permits for 18 of Altamont’s 20 wind farms in Alameda County. The permits were reissued without requirements to decrease the bird mortality caused by the turbines and without environmental analysis under the California Environmental Quality Act. Golden Gate Audubon requested an environmental review of the permitting and urged the county to mandate that the wind industry reduce bird mortality. We subsequently sued the county and wind companies in order to force a reduction in avian mortality at APWRA.
