Both. Carbon dioxide helps to keep the earth warm enough for life. This is called the greenhouse effect.
Too much carbon dioxide, which is happening now, is making the earth too warm and causing global warming, which then is causing climate change.
Yes, they are fossil fuels just as oil and release carbon dioxide (CO2), a known greenhouse gas.
Cement is made from heated calcium carbonate, clay and other compounds. These are normally naturally occurring, so will not 'harm' earth, however there is a more serious danger. Cement production releases carbon dioxide, a powerful greenhouse gas. The cement industry is second only to electricity generation for emitting carbon dioxide. 50% comes from the process and 40% comes from burning fuel in transport and production. Every 1000 tons of cement produces about 900 tons of carbon dioxide. If you mean that can you put cement on earth and then grow plants, then the answer is no. Cement is a very toxic substance that does kill plants.
Increased levels of "greenhouse gases" such as CO2 and methane in the atmosphere cause heat on the surface of Earth to be trapped in the atmosphere instead of radiating back out into space. The rise in temperature melts ice caps whose high albedos normally reflect sunlight, causing the water to warm up and further increasing the Earth's surface temperature.
When you conserve energy, you're not using as much of the fuels that harm the atmosphere as you normally would. How much would depend on how many people are conserving. One person conserving will not have as much of an impact as a million people conserving.
Global warming is an observed increase in the average temperature of the Earth's atmosphere and oceans. The average global temperature has increased by around 0.75 degrees Celsius since the start of the Industrial Age. Part of this increase may be due to natural processes, and would have occurred independently of human activity. However, the consensus of most climate scientists is that global warming is substantially the result of human activities. They say that global warming is being caused by an enhanced greenhouse effect, resulting from an increase in atmospheric concentrations of greenhouse gases. Gases that contribute to global warming include carbon dioxide, methane, nitrous oxides, chlorofluorocarbons (CFCs), and halocarbons (the replacements for CFCs). The carbon dioxide emissions are primarily from the use of fossil fuels for energy and from deforestation. Global warming is real and is happening to the earth. Governments and individuals around the world are becoming alarmed at the potential harm that can result from global warming, and are taking action to reduce our carbon emissions.
Carbon dioxide is one of the greenhouse gases. By burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity (which releases carbon dioxide) man is causing global warming and climate change. This may not damage the earth, but it will certainly harm the people, birds and animals that live here.
Global warming is a consequence of increased greenhouse gases. The primary human generated greenhouse gas is carbon dioxide. Carbon dioxide is relatively inert, and is released in such small (relative) quantities it poses no known environmental harm, outside raising earth's temperature, bleaching coral and acidifying our oceans.
Yes, they are fossil fuels just as oil and release carbon dioxide (CO2), a known greenhouse gas.
It uses electricity, most of which is generated by burning fossil fuels. This releases additional greenhouse gas in the form of carbon dioxide.
No
Carbon dioxide is a enemy because it harm the environment like the trees and flowers
Greenhouse gases, especially carbon dioxide (CO2) are absorbed by the ocean. This is turning the oceans acidic (carbonic acid). This damages corals (by bleaching) and makes it difficult for shellfish to grow shells that are as strong as before.
Carbon Dioxide (CO2) emissions, mostly.

Carbonic acid is not dangerous; carbon dioxide is nonrespirable.
Burning fossil fuels releases long-held carbon that had been hidden for millions of years.This extra carbon dioxide is a greenhouse gas that is too much for the greenhouse effect and the carbon cycle to deal with.The greenhouse effect becomes the runaway greenhouse effect.This causes global warming.A:They're non-renewable resources - means one day they will all be used up.The biggest supply is owned by a small number of nations, which means that there is a lot of politics involved.
Carbon dioxide reacts with water to form carbonic acid, making the oceans more acidic. This increases the solubility of calcium carbonate, making it more difficult to make shells.
