Loss of Biodiversity and Extiction
Transcript of Loss of Biodiversity and Extiction
design by Dóri Sirály for Prezi
Despite knowing about biodiversity’s importance for a long time, human activity has been causing massive extinctions. As the Environment New Service, reported back in August 1999 (previous link): “the current extinction rate is now approaching 1,000 times the background rate and may climb to 10,000 times the background rate during the next century, if present trends continue [resulting in] a loss that would easily equal those of past extinctions.”
They show that also
the mankind has killed
many Endangered Animal .

How does Biodiversity loss affect me and everyone else?
"I understand there may be a biodiversity crisis, but how does that affect me?”
Biological diversity is the resource upon which families, communities, nations and future generations depend. It is the link between all organisms on earth, binding each into an interdependant ecosystem, in which all species have their role. It is the web of life.
The Earth’s natural assets are made up of plants, animals, land, water, the atmosphere AND humans! Together we all form part of the planet’s ecosystems, which means if there is a biodiversity crisis, our health and livelihoods are at risk too.
But we are currently using 25% more natural resources than the planet can sustain As a result species, habitats and local communities are under pressure or direct threats (for example from loss of access to fresh water).
Biodiversity underpins the health of the planet and has a direct impact on all our lives.
Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply.
For humans that is worrying.
