Colombia's Herd of Hungry Hippos

Colombia's Herd of Hungry Hippos | Lorraine's Environmental Change &  Management | Scoop.it

"A herd of hippopotamuses once owned by the late Colombian drug baron Pablo Escobar has been taking over the countryside near his former ranch - and no-one quite knows what to do with them."

Seth Dixon's curator insight, June 26, 2014 10:33 PM

An important idea in biogeography is the concept of invasive species. An invasive species is an organism that is not indigenous to an area but causes great economic or environmental harm to the new area as it quickly adapts and alters the ecosystem.   Colombia's hippopotamus herd certainly qualifies as an interesting example to share with students of unintended ecological consequences that occur through human and environmental interactions.  For further explorations into invasive species, see this National Geographic lesson plan.

Refilling the coral reef glass

Refilling the coral reef glass | Lorraine's Environmental Change &  Management | Scoop.it
Coral reefs around the world have suffered from 3 years of coral bleaching, following three decades of record high temperatures. It is now clear that coral reefs cannot survive, unchanged, under climate change. Their final state will depend not only on societal conviction to restore coral health but also on the ability to sustain investments and action that support this commitment.

What is the problem with willows? - Rivers of Carbon | Lorraine's Environmental Change &  Management | Scoop.it
Willows love Australian rivers…. Willows do extremely well in Australian conditions, and have spread from people’s gardens out into our landscape, establishing along and within wetlands, streams and creeks in south eastern Australia, particularly in the Murray–Darling Basin.   We also used to plant willows for bank stabilisation, but we have inadvertently created a problem …

What it feels like to see Earth from space

What it feels like to see Earth from space | Lorraine's Environmental Change &  Management | Scoop.it
What the astronauts felt when they saw Earth from space changed them forever. Author and artist Benjamin Grant aims to provoke this same feeling of overwhelming scale and beauty in each of us through a series of stunning satellite images that show the effects human beings are having on the planet. "If we can adopt a more expansive perspective, embrace the truth of what is going on and contemplate the long-term health of our planet, we will create a better, safer and smarter future for our one and only home," Grant says.

A Remote Paradise Island Is Now a Plastic Junkyard

A Remote Paradise Island Is Now a Plastic Junkyard | Lorraine's Environmental Change &  Management | Scoop.it
“Henderson Island is isolated and uninhabited—but its beaches are still covered in garbage. ”

Henderson Island (article or podcast) is about the most remote place you can visit without leaving the planet. It sits squarely in the middle of the South Pacific, 3,500 miles from New Zealand in one direction and another 3,500 miles from South America in the other. Henderson should be pristine. It is uninhabited. Tourists don’t go there. There’s no one around to drop any litter. The whole place was declared a World Heritage Site by the United Nations in 1988. The nearest settlement is 71 miles away, and has just 40 people on it. And yet, seafaring plastic has turned it into yet another of humanity’s scrapheaps.
