Definition of extinction

Fact or process of a species, family or group of animals or plants becoming extinct.

In the last 500 million years, life has had to recover from five catastrophic blows.More than 99 percent of all organisms that have ever lived on Earth are extinct.

Are humans dealing the planet a sixth?

Earth is currently experiencing a biodiversity crisis. Recent estimates suggest that extinction threatens up to a million species of plants and animals, in large part because of human activities such as deforestation, hunting, and overfishing. Other serious threats include the spread of invasive species and diseases from human trade, as well as pollution and human-caused climate change.Today, extinctions are occurring hundreds of times faster than they would naturally. Climate change presents a long-term threat. Humans’ burning of fossil fuels has let us chemically imitate large igneous provinces, through the injection of billions of tons of carbon dioxide and other gases into Earth’s atmosphere each year.

Quotes

"The current extinction rate could be more than 100 times higher than normal"

"We are now changing the climate, very, very rapidly, by geological standards. We are changing the chemistry of all the oceans. We are changing the surface of the planet. We cut down forests, we plant mono-culture agriculture, which is not good for a lot of species. We’re overfishing"

"Even if we can survive, is that the world you want to live in? Is that the world you want all future generations of humans to live in? "

"It is caused by an ever-increasing population and consumption rates"

FISHING HAS WIPED OUT 90% OF THE WORLD'S LARGE FISH

FISHING KILLS 30,000 SHARKS EVERY HOUR.

FISHING IS THE GREATEST THREAT TO MARINE WILDLIFE

70% OF MACRO PLASTIC AT SEA COMES FROM FISHING GEAR.

$35 BILLION IN SUBSIDIES IS GIVEN TO THE FISHING INDUSTRY EVERY YEAR

300,000 DOLPHINS, WHALES & PORPOISES ARE KILLED BY FISHING OPERATIONS PER YEAR.
