Answer:
Concentrations of carbon dioxides are rising mainly due to energy-burning fossil fuels. Fossil fuels such as carbon or oil include carbon plants which, over the years, are photosynthesized in the atmosphere; in a few hundred years we have returned this carbon to the air
Explanation:
Even fundamental human functions — eating inhalation and digestion — generate CO2. In the life cycles of the earth, it is an essential chemical. Active plants and trees are absorbing CO2 and turning it into food with sunlight and water. There are problems when more CO2 is emitted than is absorbed by our vegetation. Activities to produce high carbon dioxide include:
- Consuming electricity: Fossil fuels emit CO2, with coal emitting twice as much gas as oil. Worldwide, 85% of energy is generated by fossil fuels. As China and India continue to industrialize, the number of coal-burning plants will rise. Today, power generation represents 41 percent of CO2 emissions in the United States.
- Transportation: Locomotive is the second greatest source for U.S. CO2 emissions for business or pleasure. Travel is also a factor internationally. A cruise ship study indicated that holidays at sea produce 12 times more CO2 than on land. 41,000 tonnes of CO2 was generated at Denmark's 11-day worldwide Copenhagen Conference on Climate Change. U.S. representatives alone produced sufficient CO2 to fill 10,000 Olympic pools.
- Building: Manufacturing produces large amounts of CO2, yet only represents 2% of US emissions. The most serious offenders are the manufacture of iron and steel and cement. These businesses use huge amounts of thermal energy to turn commodities into building products.
- Deforestation: Trees are powerful organisms that absorb CO2 from the air and remove it. It stops the process by cutting them down. While deforestation is a tiny source of increasing CO2 in the U.S., 20 percent of global CO2 emissions are due to forest loss. Fuel-burning trees and natural forest material breakdown also generate CO2.
Answer:
ethnocentric
Explanation:
Based on this scenario, I would describe Suzanne's behavior as being ethnocentric. This is simply due to the fact that she is applying her own cultural customs to that of Ancient Romans which she has never met or dealt with their customs. She is simply using her own experiences from her culture and what she knows to explain other culture's behaviors, which is exactly what an ethnocentric person tends to do.
Answer:
Improving drainage in the cities by ensuring that drainage channels are large enough to handle floodwaters and that they are never blocked. Clogged drainage's impede the flow of water resulting in a rise in water levels in the city. Ensure proper enforcement of laws that ensure that people do not settle on wetlands and riparian land. Wetlands are natural drainage's for water and settling on them is akin to blocking drainage's in a built environment. Constructing flood gates and flood walls to redirect floodwaters away from populated areas. This is especially implemented in built environments that are in low-lying lands and prone to flooding.
Answer:
C Darwin
Explanation:
Charles Darwin, the father of evolution theorised that within any population, there exists variation in traits which help the animals adapt to their environment and help them survive.
In the same vein, he believed that the breeds of dogs are all one species, but they have incredible genetic diversity.
Therefore, Charles Darwin first realized that variation mattered, even though he didn't know the exact mechanism.
