Topic: Gas emission

Objective: to identifiy what are the gas emission.

Carbon dioxide (CO₂) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH₄) and nitrous oxide (N₂O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.

Sources of greenhouse gases

Some greenhouse gases, like methane, are produced through agricultural practices, including livestock manure. Others, like CO2, largely result from natural processes like respiration and from the burning of fossil fuels like coal, oil and gas.

Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.

How does carbon emissions affect the environment?

They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.

the smoke when it is produced is imposible to disapear from the environment and are the the plants and trees that are responsible for purifiying the air but the problem worsens when huge amounts are released into the environment, causing air pollution that ends up affecting us over the time.

The garage in the rivers contaminates the waters causing the death of fish and other marine animals at the same time every year they cause the everflow in the rivers causing floods and serious problems to the people who live near the rivers so the contaminations is all waste that can cause problems.Assignment: read the text about gas emissions and make a sumary. 

Asignación: Lee el párrafo acerca de la emisión de gas.

NOTA: enviar la asignación el día jueves 23 de abril.
