Just as carnivores eat meat and herbivores eat plants, locavores only eat foods that have been grown locally. The locavore movement challenges people to buy food grown within a strict radius of where they live -- be it 50 miles, 100 miles, 150 miles (80, 160, or 241 kilometers)...
In nature, the nitrogen, phosphorous and potassium often come from the decay of plants that have died. In the case of nitrogen, the recycling of nitrogen from dead to living plants is often the only source of nitrogen in the soil. To make plants grow faster, what you need to do is ...
CO2 releases into the atmosphere in a ton of ways. The largest source of natural carbon emissions is the exchange of carbon dioxide between the oceans and the atmosphere. Animals and plants also emit CO2 through the process of respiration (breathe in oxygen, breathe out CO2)....
And we also know that sulfur pollution from coal plants and ships has likely reduced global temperatures. Indeed, new UN rules requiring ships to emit less sulfur might actually raise temperatures slightly (see “We’re about to kill a massive, accidental experiment in reducing global warmin...
How do greenhouse gases increase the temperature of our planet? a. They direct the longer wavelength heat which would normally be radiated into space back down to the surface. b. They direct the shorter wavelength radiation which would normally be radiate Which of the following ...
of the elements in the periodic table heavier than iron, including many very interesting elements, such as the neodymium in our cell phones, the molybdenum that plants rely on as the central component in the enzyme that allows them to fix nitrogen from the air, or the iodine in our bodies...
Would it emit any exhaust? Would its engine be hot? Explain. What is the throttling process in thermodynamics? Why do environmental problems exist? Think, for instance, of the pollutants that come out of coal-fired power plants that generate electricity. These include both conventional pollutants...
achieving the balance we are talking about.The healthiest way is not to emit more CO2than can be absorbed naturally by the world's forests and plants,which act ascarbon sinksthrough the process ofphotosynthesis- they take in CO2from the air and turn it into oxygen - helping to reduce ...
In Japan and South Korea, a large share of hydrogen demand is expected to come from electricity generation, as coal and gas plants begin incorporating hydrogen and ammonia into their production processes. The region will likely rely on hydrogen imports from elsewhere: for instance, Oceania, North...
With rapid industrialization, many steel and power plants bum a lot of coal. Without resorting to the clean technology, these factories emit smoke and fume directly into the atmosphere. The past decade has also witnessed a surge in the number of private cars. This would not have posed an ...
