The Wall Street Journal published a recent article concerning decline in wildlife populations worldwide. Scientist from groups such as the World Wildlife Fund and the Zoological Society of London report the downward spike in wildlife numbers is worse than they had previously thought.

It seems from 1970 to 2010, the overall animal population of animals fell 52 percent. This is a horrible rate of decline. Key factors sited for land, rivers and oceans, are habitat destruction, commercial fishing, hunting and climate change.

Of course, humans have a role in all of it. A previous report from 2012 put the rate of decline at 28 percent.

And while the animal population plummets on planet Earth, the human population continues to expand. And this sentence from the WSJ article offers a stark warming: “With the planet’s population expected to swell by 2.4 billion people by 2050, the challenge of providing enough food, water and energy will be difficult.”
