food production results in greenhouse gas emissions from the fossil fuels burned to run tractors and harvesters, for example, and from the gases released when cow manure decomposes(粪便分解) and from when cows burp and fart(打嗝和放屁).(除 了使用土地和水之外,粮食生产还会产生温室气体排放 — —...
根据第一段的第二句话 "In addition to using land and water, food production results in greenhouse gas emissions—from the fossil fuels burned to run tractors and harvesters, for example, and from the gases released when cow manure decomposes(粪便分解) and from when cows burp and fart(打嗝和...
Carbon is usually released when fuels are burned, organisms die, or when there is a fire. Most of this carbon is generally stored in the ocean, rocks, and atmosphere. The carbon cycle is how carbon atoms move from the atmosphere and are absorbed by water surfaces. ...
Concentrations of carbon dioxide, released when fossil fuels are burned, as well as other 'greenhouse gases', have risen at an alarming rate, forming a thick blanket around Earth, trapping excess heat and nudging global temperatures upwards. 化石燃料燃烧释放的二氧化碳以及其他“温室气体”的浓度以惊人...
One of the most significant challenges and health risks in today’s world is climate change. With the demand for energy, fossil fuels are burned continuously releasing masses amounts of greenhouse gasses including carbon dioxide, methane, and nitrous oxide that directly impact the atmosphere and cau...
Solar power is now as cheap as some fossil fuels. It makes 1.5% of the electricity we use.Biomass energy(生物质能)Biomass energy is energy that we get from plants around us. For example, dead wood or grass is burned in power stations. This makes electricity.Biomass energy is green energy...
E. The garbage burned is turned into fossil fuels. F. The heat produced is used to boil water. G. The steam produced is used to make electricity. . The steam produced is used to heat buildings.2、According to the passage, which of the following is NOT true? . About 2 million metric...
Coal– a sedimentary rock that can be burned for fuel. Nuclear energy– An energy source derived from splitting the atoms ofuraniumand producing a chain reaction of energy. What Are the Main Energy Commodities? With the exception ofethanoland someelectricitygeneration, the most developed commodity ...
In OTEC, we use the temperature difference between the hot surface of the ocean and the cooler, deeper layers beneath to drive a heat engine in a broadly similar way—except that no fuel is burned: we don't need to create a difference in temperature by burning fuel because a temperature ...
and that are from fossil fuels. It has all the same chemicals that hold it together to be a tough plastic. So these are not the answer. I think there's going to be room for new materials that move away from just kind of the general idea of plastic. So, you know, like mushroom-ba...
