While the earth is changing for the better all around with new innovation, the fact that global warming is a problem stays as a factor. Many people do not understand the weight of the effects of cars emissions, greenhouse gases, and how that affect the ozone layer (a layer in the atmosphere that helps protect people from harmful waves from the sun and space). Global warming has already started hurting the North and South pole, the melting of the ice in places as cold as that have started to ruin habitats in those areas. Global warming is not something to be overlooked while time progresses, the truth is that if something doesn't change soon to help this issue, the earth soon be in a lot of trouble.
