Critical Thinking.

Critical Thinking is how people think in an accurate way. You can think critically by hearing and looking closely in what surrounding you.

If you can think critically, you should think deep in yourself. After that, you can say your opinion and assumption.

Looking for evidence is requiring you to think critically. Before you say something you have to look and examine tings, so you can say what you see and look into it to get evidence.

Most people are curios and looking forward to know all of things. This must be critical thinking because you must have the knowledge of what you are thinking in.

Finally, asking yourself and other people hard questions will also make you think critically.

Carbon Footprint

Carbon footprints can be calculated using a Life Cycle Assessment method, or it can be restricted to the immediately attributable emissions from energy use of fossil fuels. The first method would take into account all carbon emissions required to build the car and dispose it. The second would account only for the fossil fuels that resulted from building and dispose it. Further, there's more than one way to run the numbers, depending on how they're going to be used. Everything has a carbon footprint, and each can be measured a couple different ways. Most carbon footprint calculations include all applicable gases, as they all contribute to the greenhouse effect and our persistently warming globe. Carbon footprint calculations generally include energy used to power our homes and transport as well as all the consumables we use on a regular basis. Once you understand, your carbon footprint is, you can start reducing it. There are many sites to calculate your own.
