Threats to Biodiversity

Extinction is a part of nature.
In fact, an estimated nine (9) percent of species become extinct every  million years or so, a rate that works out to between one to five species per year.
Now, 65 million years after that last of the dinosaurs disappeared in the most recent extinction episode, it is happening again.
But this time, species are becoming extinct at a rate many times faster some scientists say that the rate has increased to 10,000 times faster than ever  before, thus roughly 10,000 to 25,000 species are disappearing each year and dozens each day.
The exploitation of natural resources, such as the world’s oceans and forests faster than they can be renewed, i.e. overharvesting of trees for timber and oceans for food
Overpopulation – the world’s population is estimated to be over 7 billion 
Draining wetlands, clearing forests and grasslands for agricultural purposes, towns and cities
Ruining habitats due to road construction and development 
Releasing toxic pollutants into waterways and lands
Climate change – continued rise of global temperatures
Poaching(illegal hunting) of wildlife.
