History will damn him. We need to protect the environment. Many of the conflicts we have flow from environmental issues. For example, our dependence on fossil fuel. This dependence makes us beholden to the Middle East, which embroils us in wars and other conflicts. But the oil companies are too powerful, and they stifle significant talk of non-fossil fuel alternatives.
The destruction of our environment will mean the death of animal and plant life.
People will die and have died. The rollback of this deal will only make it worse.
Conflict and death will result from pulling out of the Paris Agreement.
