Rewilding Patagonia | Link TV
Three-quarters of all land on Earth is now significantly affected by human activity and the few remaining pockets of wilderness are themselves at risk of becoming ecological deserts. Agriculture, industry, urbanization, climate change — all these are decimating ecosystems and destroying biodiversity. Some 60 percent of the world's animals have been wiped out since the 1970s.
In response, a worldwide movement is under way to "rewild" the countryside. Rewilding is the restoration of an entire ecosystem to its natural state, by removing foreign species while reintroducing and protecting native ones. It begins with the removal of livestock, allowing vegetation to flourish. This encourages insects and other animals, attracting birds and other small predators. Removing fences allows for the return of herbivores, which are preyed on by apex predators — those at the top of the food chain — which then also multiply.
One rewilding initiative — right at the tip of South America, in Chile's Patagonia — is exceeding all expectations. There, two philanthropists, Kris McDivitt Tompkins and her late husband Doug Tompkins, have helped create one of the largest national parks in the world. Kris, the founder and CEO of the clothing brand Patagonia, and Doug, the founder of Esprit and North Face spent $345m buying up vast tracts of land for restoration and rewilding.
In what has become recognized as the biggest land donation in history, Tompkins has handed 400,000 hectares over to the Chilean state to be run as national parks, alongside four million hectares of land contributed by the state.

Estimates say that by 2030, if we carry on as we are, the world will have only 60 percent of the water it needs. In India's Ladakh, rising temperatures are leading to glacial melt and water shortages in the mountains of the Himalayas. The Hashemite Kingdom of Jordan is also struggling as it experiences severe drought.
"earthrise" investigates the local solutions being developed in Ladakh and Jordan to help ease the increasingly worrying water problems.
For centuries, mankind has been hooked on the concept of a mysterious continent at the end of the world. Ancient Greeks and Romans called it "the unknown southern land" and a century ago, Captain Robert Falcon Scott paid the ultimate price on his famous South Pole expedition.
Antarctica, the planet's southernmost continent, is home to spectacular biodiversity — from emperor penguins and blue whales to krill. But climate change, oil drilling and an ever-expanding commercial fishing industry are threatening this undisturbed land and its iconic creatures.
The survival of people and wildlife depends on the health of the land. The economic prosperity of a country is linked to the richness of its resources. But our demand for these is destroying the land and all it harbors.
Our consumption of the earth's natural reserves has doubled in the last 30 years. Now, a third of the planet's land is severely degraded. Each year, we lose 15 billion trees and 24 billion tonnes of fertile soil. And at least 10,000 species go extinct every year.

Every year seven million people die from air pollution. It's the world's biggest environmental killer.
Italy is Europe's most polluted country: in 2012, more than 84,000 people in the country died prematurely owing to bad air quality. To combat this, scientists have developed a new type of photocatalytic cement that absorbs pollutants and turns them into harmless salts.
Antarctica, one of the most remote and desolate locations on Earth also functions as one of the world's main cooling systems. However, after decades of greenhouse gas emissions and global warming, parts of the continent are now warming faster than anywhere else on the planet.
Over the years, climate change has led to increased erosion of the continent, altered ocean currents and affected wildlife. Warmer currents are now flowing further south, towards the icy terrain, contributing to glacial melt, rising sea levels and drastically changing habitats.
