Biodiversity

 Hi guys 

This is my work from what i did for biodiversity.

fact 1

about one million plant and animal species face the threat of extinction

Extinction is a major part of history of our earth. Species have come and gone,

while others have thrived regardless of the changes. unfortunately ,

human activities speed up the extinction rate we observe. When we encroach on habitats,

pollute water bodies, disrupt migration paths, and so on, we not only impact biodiversity

but, at worst, we threaten the ongoing existence of the creatures with whom we share our planet.

Fact 2 

At least 680 vertebrate species have gone extinct since the 16th century.

Local varieties, species, wild populations, and domesticated plants and animals’ breeds deteriorate,

shrink, or vanish. Species diversity and living organisms are becoming extinct.

Fact 3 

The majority of native species in land based habitats have fallen by a minimum of 20% since the 1900s. 

Fact 4

Extinction threatens more than 40% of amphibians.

Fact 5 

Nearly 33% of reef forming corals face the throat of extinction.

Fact 6 

Extinction threatens more than the third of all marine mammals.

This negative trend may continue till 2050 and beyond. It will reduce only when we make transformative

changes that affect land- use, exploitation of animals, and climate crises.

In our different regions of the world, we should see a significant difference only once we significantly

reduce the harm we cause to the environment and its impact on biodiversity.

Fact 7

by 2016, more than 9% of all domesticated breeds of mammals used for food and agriculture

had gone extinct, and at least 1,000 more species remain threatened. 

    

The earth is home to different species and communities of species.

Biodiversity is unique in all parts of earth. As the environmental conditions change

from what millions of species adapted to, many are under the threat of extinction.

Every species is valuable and in need of protection. These 26 biodiversity facts point

out interesting aspects of our earth’s biosystem alongside the species threatened

by extinction.   

Fact 8

there has been a 68% average decline in the population sizes of mammals, birds, amphibians,

reptiles, and fish between 1970 and 2016. These biodiversity facts show that life around us,

our earth’s biodiversity, is being destroyed at an unprecedented rate. Human activities and habits

continue to degrade and destroy the earth, forest, wetlands and threaten our well being.

This wwf research initiative to develop pioneering modeling that can halt and reverse terrestrial

biodiversity loss.

Fact 9

human activities are overusing the earth’s biocapacity by an estimated 56%.

Biodiversity facts show that the last 50 years transformed the world. And we can observe many

of these changes without reading a report. The explosion in global trade, consumption, and human

population growth, as well as ecosystem diversity, are changing everything around us.

At this point, we are beyond the earth’s biocapacity. This will affect the earth, it's life forms,

and it's survival in the future.

Fact 10

human activities have significantly altered three -quarters of land based environments.

As human continue to encroach on land resources, we send the earth’s abundance downwards.

We do this by expanding our cities into forest areas, cutting down trees, harvesting forests for

food and medication, and so on. This trend is less severe in regions  where indigenous peoples and

local communities reside. Many indigenous tribes still manage the lands they live on with sustainable

practices passed down for generations. Hence, there are fewer bushes burning, tree cutting, forest

burning, or land degradation in these areas. 

Fact 11

there are 8 million  total estimated animal and plant species on earth. 

Fact 12

we can find an estimated one-fifth of all known species of mammals, birds, and plants in africa.

The biodiversity facts show that africa has broad species diversity and is immensely rich in biodiversity 

 Thos ecosystem includes wetlands, savannahs, coral reefs, tropical fores, marine and freh water

habitats, and montane ecosystems.
