Science proven time and again that climate change exists, there is no denying it. Huge amounts of scientists have stated that it is real. And it is extremely harmful to our environment and to people (I just read the other day in the NYT that about 6.5 million deaths are caused by air pollution every year). Despite how many people want to deny it for one reason or another, something needs to be done about it before the effects of climate change are irreversible. Now is the time to do this.
