other than that, carbon also make the IPU higher and more than 100 and the IPU more than 100 is not healthy. carbon monoxide will make green house effect and impact our ozone layer

i agree with u rizal. burning fossil fuels is very dangerous. many impact because of the burning fuels

2. Land use and land cover change (e.g. deforestation)

Large amounts of carbon are stored in living plants (c.1,000 gigtones). Therefore, land use changes, especially the clearance of forests (which are very densely inhabited by plants, and therefore contain a large amount of carbon), can influence the carbon cycle in two ways. Firstly, the removal of vegetation eliminates plants which would otherwise be capturing carbon from the atmosphere through photosynthesis. Secondly, as dense forests are replaced by crops/pasture land/built environments, there is usually a net decrease in the carbon store, as smaller plants (and worse still, concrete) store far less carbon than large trees. Deforestation also allows much more soil to be eroded, and carbon stored in the soil is rapidly taken into rivers.

i just know carbon is carbon dioxide and carbon monxide and it,s not good for our environment especially the carbon monoxide. it,s will affect to our country and make the haze proble in Malaysia. Furthermore, it will effect our healthy

What are the main impact of human activities on carbon cycle?

1. Burning of fossil fuels.

Under natural conditions the release of carbon from fossil fuels occurs slowly, as they are subducted into the mantle, and CO2 is released through volcanic activity. However, humans are heavily reliant on fossil fuels, and extract it from the lithosphere in great quantities. Burning coal, oil, natural gas, and other fossil fuels – for industrial activity and power generation for example, removes the carbon from the fossil fuels and emits it as CO2 into the atmosphere.

Because of the cyclical nature of the carbon cycle, the impacts humans cause can lead to a number of amplifications and feedbacks. Increasing atmospheric CO2 and CH4 (along with other greenhouse gases) causes higher global air temperatures which in turn increases decomposition in soil, thereby releasing more CO2 to the atmosphere. Increases in global temperature also affect ocean temperatures, modifying oceanic ecosystems and having the potential to disrupt the oceanic carbon cycle, limiting the ocean’s ability to absorb and store carbon.

What is the meaning of carbon cycle?

Carbon is critical to sustain a huge range of Earth’s functions. Not only is it present in all living beings, it is a major component of a number of minerals (e.g. graphite and diamond). This means that it is abundant across the world, in: the atmosphere (air); biosphere (living and dead organism organisms); hydrosphere (oceans, rivers, and lakes); and lithosphere (soil and rocks). These act as storage areas of ‘reservoirs’ of carbon, either in the short-term (a few minutes) or long-term (millions of years).  As the Earth is such a dynamic environment, processes such as erosion, evaporation, photosynthesis, respiration, and decomposition constantly move carbon between these reservoirs. Carbon enters, is stored, and leaves the different spheres of the Earth through different methods, and in different quantities

How does the carbon get out of living things?

When fossil fuels burn, we mostly get three things: heat, water, and CO2. We also get some solid forms of carbon, like soot and grease.

So that's where all the old carbon goes. All that carbon stored in all those plants and animals over hundreds of millions of years is getting pumped back into the atmosphere over just one or two hundred years.

How does carbon get into living things?

Plants take in CO2. They keep the carbon and give away the oxygen. Animals breathe in the oxygen and breathe out carbon dioxide.

Plants and animals depend on each other. It works out well. For hundreds of millions of years, plants and animals have lived and died. Their remains have gotten buried deep beneath Earth's surface. So for hundreds of millions of years, this material has been getting squished and cooked by lots of pressure and heat.

So what happens to all this dead plant and animal stuff? It turns into what we call fossil fuels: oil, coal, and natural gas. This is the stuff we now use to energize our world. We burn these carbon-rich materials in cars, trucks, planes, trains, power plants, heaters, speed boats, barbecues, and many other things that require energy.

Hi.. So, what is up with carbon? What I understand,

carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table.

Carbon is a very abundant element. It exists in pure or nearly pure forms, such as diamonds and graphite, but it can also combine with other elements to form molecules. These carbon-based molecules are the basic building blocks of humans, animals, plants, trees and soils. Some greenhouse gases, such as CO2 and methane, also consist of carbon-based molecules, as do fossil fuels, which are largely made up of hydrocarbons (molecules consisting of hydrogen and carbon).
