Currently, China's greenhouse gases account for 26% of the world's emissions. Can you create a carbon-neutral community in a densely populated region?

Yes, it is possible to create a carbon-neutral community in a densely populated region.

Explanation:

The greenhouse gases are the gases that causes global warming and greenhouse effects. Global warming is a scientific theory in which increased levels of atmospheric carbon dioxide and other greenhouse gases are linked to general rising of temperature around the world. The unabsorbed carbondioxide rises to the upper atmosphere and blocks the radiation of solar energy back into the space. This precipitates a global temperature increase called 'greenhouse effect'.

The different greenhouse gases includes:

--> carbon dioxide

--> carbon monoxide

--> Nitrogen Oxides

--> Methane gases

--> Lead and

--> Chlorofluorocarbons.

According to recent research conducted, China's greenhouse gases account for 26% of the world's emissions. This is because China is densely populated with an increased demand on natural resources( fossil fuels) which gives off these greenhouse gases that's harms the environment. A carbon neutral community can be achieved is such densely populated areas through the following methods:

--> cutting current use of Fossil fuels.

--> placing heavy axes on gasoline and emission on each unit of fossil burned to reduce emission of carbon dioxide and other air pollutants.

--> reduction in the use of coal which emits 60% more carbondioxide per unit of energy produced than any other fossil.

--> shifting to perpetual and renewable energy resources that do not emit carbondioxide over the next 20 - 30 years.

--> Putting the population growth under a check

--> Planting of tress.

--> Educating people on harmful effects of global warming.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
