When it comes to managing crocodiles, we are learning that it is actually more important to manage people. Learning how to keep people safe from crocodiles will ultimately protect visitors to croc territory as well as the crocodilians themselves.

Crocs are apex predators, and as with all apex predators, they are critical to the environment: if you lose the crocs, you'll lose the barramundi, you'll lose the crabs - a catfish can eat 30,000 barramundi fingerlings, and who do you think eats the catfish? Crocs.

Never walk past a problem with an animal - fix it.

It pays to be in the best shape possible when you're wrangling the largest reptiles on Earth!

But my point is that you design something in the end that precludes any unhealthy trading practices that are not going to serve your environmental or your economic objectives but now is not the time to do it.

We need senators who have studied physics and representatives who understand ecology.

Environmental protection and economic development are not in conflict. Environmental protection is not a burden but a source for innovation. It can increase competition, create jobs, and lifts the economy.

Actually, climate change is really about the wellbeing of people. It is not a very vague concept or a vague problem that is out of our everyday lives. It is actually affecting our everyday lives, and this is the fundamental fact that everybody should keep in mind while working toward a low-carbon society.
