The same mentality that leads to environmental despoliation, environmental destruction, also leads to damage to people.

Yet again, unscientific claims were being circulated broadly, but the scientists' refutation of them was published where only fellow scientists would see it.

We don't survive without plants and animals because we rely on them, we rely on plants to put oxygen into the atmosphere, we rely on ... fish and crops and cows to eat.

Many people have the impression that there is significant scientific disagreement about global climate change. It's time to lay that misapprehension to rest. There is a scientific consensus on the fact that Earth's climate is heating up and human activities are part of the reason. We need to stop repeating nonsense about the uncertainty of global warming and start talking seriously about the right approach to address it.

The same mentality that leads to environmental despoliation, environmental destruction, also leads to damage to people.

What to do about climate change is political, it's social, and it's moral, which is one of the reasons the scientific community reached out to the Pope, to ask for his involvement in this issue.

I think Pope Francis is our Pope Francis. I mean, the point of him is that he's a global leader, and he's trying, I think he's embracing that role.
