![]() This mostly comes down to the fact that in order to breed and keep enough animals for us to eat, farmers use up more resources than they raise. Living sustainably with the world around us means more than just cutting down on fossil fuels and placing no-fishing zones, it also means changing our diet. As Attenborough plainly puts it, we need to switch to a plant-based diet, as our planet simply cannot support billions of meat-eaters. The healthier the marine habitat, the more fish there will be and the more there will be to eat," he says. " Fishing is the world's greatest wild harvest, and if we do it right, we can continue because there is a win-win at play. The wholesale decimation of species has a profound impact on the nutrient cycle and will lead to our oceans becoming barren - destroying a vital source of protein and nutrients for terrestrial life as well as aquatic life. By eliminating these species, we are destroying the balance of Earth's oceans' needs in order to sustain themselves. Introduce no-fishing zonesĪttenborough's 2001 Blue Planet, as well as A Life on our Planet explain a tremendous amount about our oceans, including the connections between what is above ground and what lies below the waters.Īround 90 percent of all large fishes have disappeared from the world's oceans in the past half century, the devastating result of industrial fishing. The benefits of renewables include more affordable energy, cities that are cleaner and quieter, and an end to the fear that we will run out of energy. We can, and should, he stressed, make them our only source of energy. We can instead use the renewable energy available from sunlight, wind, water, and geothermal. Ships are now able to cross previously unnavigable waters as sea ice is melting, and this trend is on an upward scale.īy phasing out fossil fuels and turning to renewable energy, Attenborough explains, we can help restore Earth's biodiversity. Unfortunately, our oceans aren't able to absorb all this excess heat we're creating, and our North and South Poles are warming - something that was also fully detailed in Attenborough's spectacular 2011 documentary, Frozen Planet.Īlready, the summer sea ice in the Arctic has reduced by 40 percent in just 40 years. ![]() If we continue in this way, he points out, we will continue to warm our planet to unsustainable temperatures and ruin Earth's biodiversity. Some of these finite and harmful resources that we as humans have been depending on are fossil fuels.īy burning coal and oil the global air temperature has risen by one degree Celcius just in the course of Attenborough's lifetime. "We are ultimately bound by and reliant upon the finite natural world about us," states Attenborough in this film. We've heard these ideas before, but Attenborough's personal connection and gravitas help them to hit home in a much more compelling way. It's not all doom and gloom, though, as Attenborough shares his knowledge about how we can rebalance biodiversity and restore the balance of nature, while at the same time create a healthier and more equal world for humans. In staggering contrast, the final figures shown are from 2020, when the world's population was 7.8 billion, our remaining wilderness had plunged to 35 percent, and the parts per million of carbon dioxide in the atmosphere had soared to 415. In 1937, for example, the world's population was 2.3 billion, the remaining wilderness sat at a respectable 66 percent, and there were 280 parts per million of carbon dioxide in the atmosphere. It spans his lifetime and, in it, he shares chilling facts of how our Earth has changed over that time.įor every significant chapter in Attenborough's life, a panel of statistics comes onto the screen. The 83-minute long film is Attenborough's "witness statement," as he calls it. In A Life on our Planet, which you can find on Netflix, Attenborough shares penetrating and invaluable insights about how our planet has changed in recent decades. These lessons, if properly followed, may allow us to preserve our world. Fortunately, Attenborough also offers a number of lessons for humanity. His work makes it clear that, if nothing is done, the world as we know it, and have known it, will cease to exist. By blending impactful storytelling with facts, beautiful images, and a lifetime's worth of information, Attenborough gets the message across about sustainability in a way no scientific paper can. A post shared by A Life On Our Planet of retiring after a long career, the 94-year-old Attenborough is making it his top priority to call us all into action and implore us to live sustainably.
