Carbon Footprint

Ok, so I read an interesting article today that stated that driving actually produced almost 4 times less CO2 than walking if one assumes that beef is used to fuel our bodies.

No real surprise there since the commercial beef industry is known for being less than environmentally friendly. However, it made me wonder how much of a carbon footprint other commercial agricultural endevors have.

I’m also curious how much CO2 individuals actually produce from their own bodies while walking.

Can anyone point me to such data?

Is it actually possible that driving does, in fact, produce less emissions than walking when all "fuel" sources are considered?

I want to see the images which shows that how to protect the environment.

Cities and developers across the globe recognize that they can increase asset value and attract business/people through sustainable development. Sustainable development includes improving esthetics, mobility, the environment, and energy systems. The US census determined that 80% of the population now lives in cites, up from 40% one hundred years ago. The Brookings Institution’s Metropolitan Policy Program reports that approximately 50% of the buildings that will exist in 2030 have yet to be designed. This represents a tremendous opportunity to apply sustainable development concepts. Unless cities and developers are provided with alternatives to the current energy production, distribution, and supply system; fossil fuel energy consumption will surge by 34 quads while renewable sources increase by only 3 quads over the next 23 years . This continued emphasis on fossil fuels is expected to increase carbon emissions by over 2200 million metric tons over this same period. Through partnerships with private sector, universities, and governments; companies can finance, design, and build more efficient, smarter, and esthetically pleasing energy systems. Archimedes said “give me a lever long enough and I can move the world”. Cities and developers can provide this lever by integrating sustainable energy models and practices into community development and redevelopment projects. This includes efficient land use design, technology ready infrastructure, transit oriented development …

Hi, does sleeping in a humid environment cause headaches and back pains? Would a air humidifier help? Thanks.

Butterfingers! Ha, of course not, this is serious science. NASA should open a theme park, because that just looks fun. [ via Boing Boing , who explain the sciency bits ] Watch Video ›
