Author of How To Save Our Planet: The Facts
Professor of Earth System Science at University College London

I think the most important thing is realizing how much impact humans have had on the planet. For example, did you know that we move more rock and sediment than all the natural processes put together? We also have created enough concrete already to cover the whole world in a layer that's two millimeters thick, and that includes the oceans. We have also created and make something like 300 million tons of plastic every single year, which we know ends up in our rivers. It ends up in our oceans. And we've also found that microplastics have been found in human blood. So this is the impact we're having all around the world. We've also cut down 3 trillion trees, that's half the trees on the planet. We have doubled carbon dioxide in the atmosphere. We've increased methane by about 150%, which has led to a warming of the planet of about 1.2 degrees Celsius. And If you weigh the land mammals, 30% of that weight is us humans. There are 8 billion of us, and I have to say a few of us could lose a few pounds, but 67% of that weight is our livestock. And just 3% is those wild animals. So in less than 5,000 years, we've gone from 99% being wild animals to less than 3%. That's how much impact we humans have had on the planet.

Co-author of Strange Natures: Conservation in the Era of Synthetic Biology
Principal at Archipelago Consulting · Former VP for Conservation Science & Strategy, Wildlife Conservation Society

The field of synthetic biology, which is known by some as extreme genetic engineering – that's a name mostly used by people who don't like it. It amounts to a set of tools that humans have developed to be able to very precisely and accurately change the genetic code, the DNA of living organisms in order to get those organisms to do things that humans want. So the applications in medicine are predominantly devoted to trying to make us healthier people, and they range from some really exciting work on tumor biology to work on the microbiome, which is all of the thousands and tens of thousands of species that live on our lips, our mouths, our guts, our skin. And in agriculture, it's primarily directed at crop genetics, trying to improve the productivity of crops, the nutritional value of crops, the ability of crops to respond to climate change, and a whole variety of other things. Some people may have heard of one of these tools called CRISPR used to very precisely alter the sequences of DNA.

Lead Author of Climate Change Biology, and Defending Biodiversity: Environmental Science and Ethics
Vice President of Research, Wilfrid Laurier University

Climate change is certainly going to affect biodiversity. Some species will benefit from climate change, but others will not, and we'll have different ecosystems, different biotic communities as a result of this. I think the impacts that are likely are pretty clear, and I think that's a pretty good reason to do all those things we can do without completely destroying our economies and our communities because those things have moral value as well. It's not just the environment that we think is important. We also think humans are important, then doing the things we can do now, do the less painful things first. We should have done them already, and we should be now thinking about how to do the harder things.

Founder & President of People for the Ethical Treatment of Animals (PETA)

They’re not human traits. They’re all shared traits because, of course, we all love. We all love our families, or not. We all grieve if somebody we love disappears or dies. A family dog, perhaps. A grandfather. We all feel loneliness, we all feel joy. We all really value our freedom. And so I think, if anything, looking into the eyes of the animal, even online, you see a person in there. There’s a someone in whatever the shape or the physical properties of that individual are. And that lesson is that I am you. You are me, only different. We are all the same in all the ways that count…Any living being teaches you– Look into my eyes. And there you are, the reflection of yourself.
