How human actions affect global climate change...

So it's not breaking news that planet Earth's climate is getting warmer. Climate change happens and has happened naturally throughout Earth's history but what is different about what is happening today is that it is mostly caused by human action. Ever since the industrial revolution, we have been releasing incredible amounts of CO2 into the atmosphere. Factories and automobiles are the main causes of this CO2. Factories and cars let out incredible amounts of CO2 together.

Some people may ask, "So who cares if there's this gas in the atmosphere? What could happen?" Well the answer is that more people should care and that a lot could happen. Usually, energy from the sun enters the Earth and then a lot of it gets reflected back into space and out of our atmosphere. With all the excess CO2 being released, the atmosphere thickens. The energy has less chances to escape and gets trapped inside Earth's atmosphere and then global temperatures rise. This is known as The Greenhouse Effect. This is the main cause of today's Global Warming crisis.

Many people are worried about what might happen if Global Warming keeps going at this rate. A big part of the problem is how our biosphere is being affected.
