Rethinking How City Dwellers Get Their Food

چکیده
Do you perhaps live in a city, or have visited one? Cities are exciting places where there is often lot going on. They offer variety of job opportunities and many leisure activities, like movie theaters, shopping malls, parks, museums. Currently, Earth’s greatest population growth happening within cities. Even though cities cover only 2–3% the land, they consume approximately 75% world’s energy produce 80% carbon dioxide that released into atmosphere. Until now, not needed to grow their own food, but this makes them dependent on food sources can be quite far away. This article will describe how urban agriculture help better deal with climate change other environmental problems, food-growing method improve living environments for people at same time.

How can EcoCity get its food?
Designing an ecologically responsible EcoCity of 550,000 people begins by confining it to 8500 ha, which spares surrounding land for farming and for Nature. Because an American diet requires 126,000 ha and even a survival diet needs more cropland than can be found inside its boundaries, EcoCity will cast shadows of farming outside its limits. EcoCitizens will cast wider shadows if farmers grow ...
متن کاملHow do galaxies get their gas?
Not the way one might have thought. In hydrodynamic simulations of galaxy formation, some gas follows the traditionally envisioned route, shock heating to the halo virial temperature before cooling to the much lower temperature of the neutral ISM. But most gas enters galaxies without ever heating close to the virial temperature, gaining thermal energy from weak shocks and adiabatic compression,...
متن کاملFood and Culture: How Americans are Rethinking What they Eat
This event is made possible by the US State Department’s renewed focus on agricultural development and food security as a foundation for global economic and political stability. After decades of relative neglect, food and agriculture are back on the agenda for U.S. policy. The many challenges posed by this sector -and the actions needed to overcome obstacles to success – are extremely location-...
متن کاملTransport networks and their use: how real can modelling get?
The context for modelling transport systems and their use is set out. Such modelling is based on representing the transport system by a network of nodes and links, and the characteristics of this representation needed to reflect the principal realities of the system are outlined. The characteristics of use of the system that need to be reflected are described. Purposes of the modelling are set ...
متن کاملHow Black Holes Get Their Kicks: Gravitational Radiation Recoil Revisited
Gravitational waves from the coalescence of binary black holes carry away linear momentum, causing center of mass recoil. This “radiation rocket” effect has important implications for systems with escape speeds of order the recoil velocity. We revisit this problem using black hole perturbation theory, treating the binary as a test mass spiraling into a spinning hole. For extreme mass ratios (q ...
