how can we save the world?

Humans only make up about one ten thousandth of the biomass on Earth, but our impact on the planet is drastically out of proportion to our numbers. In the last 250 years we have added over 400 billion tons of carbon to the atmosphere and approximately half of that has happened since the mid-1980s. No other organism in Earth’s history has altered the environment so much so quickly. It’s not just the amount of pollution we produce either; humans have invented entirely new kinds of pollution too. Polythene, chlorofluorocarbons, organophosphates and synthetic hormones didn’t exist in the environment until humans created them. Other toxins, like heavy metals and radioactive isotopes, were only there in trace amounts until the industrial age found new ways to refine and concentrate them. These pollutants are…

ground pollution

Land pollution isn’t just about the space that is taken up by landfill. A city the size of New York could fit all of its rubbish for the next thousand years in a landfill 56 kilometres long by 56 kilometres wide. That sounds like a lot, but that’s the waste of just 2.5 per cent of Americans buried in just 0.03 per cent of the country’s land area. And that land isn’t gone forever – eventually a landfill site will just become a grassy hill. The real source of land pollution is all of the other things that don’t end up in landfill. Copper and aluminium mining generate huge piles of powdered rock, called ‘tailings’, left behind after the metal has been extracted. These tailings are high in toxic heavy metals,…

air pollution

Air pollution is the introduction of gases and particles into the atmosphere that have harmful effects on living creatures and the built environment. According to the World Health Organiation, 7 million premature deaths are caused every year by people inhaling polluted air – that’s one in eight deaths worldwide. Once released into the atmosphere, pollutants are impossible to contain and – depending on prevailing weather patterns – have the potential to affect people who are hundreds or even thousands of kilometres from the source. Over the last half century, the nature of the problem has altered. In the developed world, smog-causing emissions of noxious smoke, sulphur dioxide and particulates associated with incomplete fuel combustion have been curbed by technologies like flue-gas desulphurisation systems, soot scrubbers and catalytic converters. Gases that deplete…

ocean pollution

Oceans cover 71 per cent of our planet’s surface and contain an estimated 1.5 million species, but that hasn’t stopped humanity treating the sea as a giant, watery rubbish bin. We’re familiar with tragic images of seabirds whose feathers are clogged with viscous black oil. But catastrophic spills from tankers account for just a fraction of oil pollution in the sea; street runoff, vehicle exhausts and industrial waste are all chronic contributors to the problem. Indeed, almost all marine pollution stems from activities on land. Runoff from farms introduces pesticides and insecticides into the aquatic food chain, as well as an overabundance of nutrients in the form of fertiliser. This causes populations of algae to spike, draining the surrounding waters of oxygen and suffocating other marine life. Finally, human-made rubbish is ubiquitous throughout…

what’s inside an octopus?

Imagine a superhero with the ability to instantly disguise not only his skin to camouflage himself, but also his texture. Imagine that this guy possesses powerful rocket boosters to move him in super-quick time, and that he has a smokescreen ability to confuse his enemies. He can also fit through any gap, move in and out of water easily, walk on any substance the right way up and upside down, and even inject a deadly poison that turns his enemies to mush. Incredibly, the octopus boasts all of these amazing powers (apart from the rocket boosters – the octopus has a powerful siphon instead, using water pressure for quick getaways). These animals are the aquatic, advanced and intelligent cousins of slugs and snails, in the phylum Mollusca.…
