The threats against Israel are growing.

It is hard to find a country friendlier to Israel than Canada these days. No other country in the world has demonstrated such a full understanding of us.

Every place in the world where there are two peoples - two religions, two languages - there is friction and conflict.

You cannot stop an Islamist tsunami by building a small island somewhere in the ocean.

Even as we continue to carry the banner of civil rights and environmental justice, we've also got to focus on many, many people - for them, life starts with a good job.

We will not overcome world poverty unless we manage climate change successfully. I've spent my life as a development economist, and it's crystal clear that we succeed or fail on winning the battle against world poverty and managing climate change together. If we fail on one, we fail on the other.

I align myself with almost all researchers in assuming that anything we do is a composite of whatever genetic limitations were given to us by our parents and whatever kinds of environmental opportunities are available.

We need healthy forests if we want to protect our climate. As the climate changes, forests become more vulnerable to insect outbreaks, droughts and wildfires. Simultaneously, when our forests are destroyed, their carbon is released back into the atmosphere, further impacting climate change. It's a horrifying one-two punch.
