Sir David appears to be shifting his focus to the issue of overpopulation, and the world should take heed. Attenborough during the London premiere of Blue Planet II. Spend a minute watching the world population counter on Worldometers tick up and you'll realize how rapidly we're growing in numbers. When I first saw that figure I was shocked - but not quite as much as when my assistant Phil discovered that there are now more people living in China than there are people living in all of Europe. The only consolation is that we're also growing in wealth so our odds of survival must be improving.
Attenborough's warning comes at a time when there's increased concern about environmental issues, particularly climate change. But he says this problem could be solved if everyone simply chose to have fewer children - or even no children at all.
He says: "We need to accept that we are going to keep on having more and more people coming into the world who require food, water, energy, and other resources. So if we aren't going to kill off whole species of animals and plants, we had better start thinking about ways of rationing what little we have left."
So would Sir David like us all to stop having children? No! He wants us to have less wasteful children. And he's not the only one - many scientists fear that we're putting ourselves out of business by continually consuming their natural resource.
Sir David Attenborough is a defender of people and the environment. Over the years, he has repeatedly warned us that we are in our "final opportunity" to modify our behavior and avert catastrophic climate change damage to our world. He encourages people to "avoid all forms of waste," including energy, food, and plastic. He also advocates for more sustainable transportation methods and renewable energy sources.
Attenborough started making wildlife documentaries for television in 1955, when he was just 28 years old. He hasn't stopped since then! There have been over 100 episodes of his documentary series aired so far. The series focuses on different topics within ecology, ranging from insects to elephants, and everything in between.
He has won several awards for his work, including two BAFTAs and a Palme d'Or. In 2007, Attenborough was given a Nobel Peace Prize for his efforts to raise awareness about climate change.
Today, Sir David Attenborough is one of the most respected scientists in the world. He's known for his incredible longevity in science (he's now 90 years old), his deep understanding of biology, and his desire to educate people about our planet's living resources.
Attenborough has played an important role in bringing attention to environmental issues. By showing how precious our wild animals are when they're alive and in their natural habitats, he has helped spark global changes toward conservation.
But, just when you fear the picture is about to suffocate you with gloom, Attenborough lets the light in. In the final 30 minutes, his message is that if we act now, it is not too late. Stop the world's population from growing any further. Establish no-fishing zones. Protect ancient forests. Save marine ecosystems. And then look around you: "The future may not be what we expect, but it's going to be wonderful."
Attenborough's plea comes as no surprise to those who have watched him over the years. The broadcaster has been making documentaries for more than 60 years and has always believed that humanity has a responsibility to look after this planet. He says he will keep preaching about climate change until they shut him up in a museum.
And yet still people are voting with their wallets and buying products which are bad for the environment. Some people believe that we need to use fossil fuels because they offer the only way to efficiently transport goods across countries and within countries to where they're needed. Others think that deforestation and ocean pollution are useful ways to produce food and make homes. Still others claim that increasing use of renewable energy is expensive and not ready for mainstream usage yet.
There is no single perfect solution, but there are many things that we can do to make our environment a better place. For example, we could stop using plastic bottles and switch to reusable cups instead.
