Marine Species on 'Brink of Collapse,' Says WWF Report
A new report on the health of the ocean finds that the marine vertebrate population has declined by 49 percent between 1970 and 2012.
World Wildlife Fund: Half of all marine life 'wiped out since 1970' http://t.co/93XYxAgwzh http://t.co/OR76L7YtOG— ITV News (@ITV News)1442363703.0
WWF’s Living Blue Planet Report tracks 5,829 populations of 1,234 mammal, bird, reptile and fish species through a marine living planet index. The evidence, analyzed by researchers at the Zoological Society of London, paints a troubling picture. In addition to the plummeting number of marine vertebrate species, populations of locally and commercially fished fish species have fallen by half, with some of the most important species experiencing even greater declines.
These findings coincide with the growing decline of marine habitats, where the deforestation rate of mangroves exceeds even the loss of forests by 3-5 times; coral reefs could be lost across the globe by 2050 and almost one-third of all seagrasses have been lost.

Global climate is one of the major drivers causing the ocean to change more rapidly than at any other point in millions of years. The oceans store huge quantities of energy and heat, but as the climate responds to increasing carbon emissions, the exchange intensifies. This may result in extreme weather events, changing ocean currents, rising sea temperatures and increasing acidity levels—all of which aggravate the negative impacts of overfishing and other major threats such as habitat degradation and pollution.
Finding Solutions for Saving Oceans
Though the challenge seems immense, it’s possible for governments, businesses, communities and consumers to secure a living ocean. To reverse the downward trend we need to preserve the oceans natural capital, produce better, consume more wisely and ensure sustainable financing and governance.
Our ocean needs a strong global climate deal and work is already underway as President Obama and leaders of the Arctic nations recently pledged to work together to boost strong action on climate change. But more needs to be done to prioritize ocean and coastal habitat health.

In 1999 a cheering crowd watched as a backhoe breached a hydroelectric dam on Maine's Kennebec River. The effort to help restore native fish populations and the river's health was hailed as a success and ignited a nationwide movement that spurred 1,200 dam removals in two decades.

We pet owners know how much you love your pooch. It's your best friend. It gives you pure happiness and comfort when you're together. But there are times that dogs can be very challenging, especially if they are suffering from a certain ailment. As a dog owner, all you want to do is ease whatever pain or discomfort your best friend is feeling.
The excess carbon dioxide emitted by human activity since the start of the industrial revolution has already raised the Earth's temperature by more than one degree Celsius, increased the risk of extreme hurricanes and wildfires and killed off more than half of the corals in the Great Barrier Reef. But geologic history shows that the impacts of greenhouse gases could be much worse.

Europe is in a panic over the second wave of COVID-19, with infection rates sky-rocketing and GDP plummeting. Belgium has just announced it will no longer test asymptomatic people, even if they've been in contact with someone who has the disease, because the backlog in processing is overwhelming. Other European countries are also struggling to keep up testing and tracing.
