For the next week, try the best you can to pay attention to sounds. You will start hearing all these sounds coming in. Once you let them in, you've already done the first and most critical thing, you've honored that information by including it. And by doing that, you've actually changed the world.

If I hold up a red square for 30 seconds and take it away, you will see a perfect green square. It's how the eye works. So if you want to paint a really good red painting, you have to strategically place in some green, so the eye is brought back.

When you walk into a room, you assess it instantaneously, habitually, before you're even aware of it. I mean, you make sure there's not a hole you're going to fall into, but mostly you're not even aware of what you're thinking.

The thing about a plant is, let's say it will have 50 or 100 little points of bright red. If you look at the thing as it goes down, it becomes green in a way... It is way more spectacular than pointillist paintings where these things are played with, but never to the level of what happens in nature.

Across energy, food, transportation, housing, and all of that, very little of our progress is going to be through getting people to voluntarily consume less. People resist that tremendously. What we have to do, if we want to succeed, is provide more of the clean, non-polluting, climate-safe options in all of these.

I write a lot of environmental stories.

As a member of the bipartisan Climate Solutions Caucus, I'm committed to finding consensus on legislation to address our environmental and energy challenges.

Even the government understands that the environmental challenge is so big that no single agency can handle it. It needs collaboration among all the stakeholders - companies, governments, NGOs and the public. Public accountability will be the ultimate driving force.
