Biodiversity Handout

Definition: biological diversity in an environment as indicated by numbers of different species of plants and animals.

New species get discovered every day. Especially in the Amazon Area. Scientists think that the Earth has between 1,75 mill. and 13 mill. different species of plants and animals.

There is an international red list by the World Conservation Union and which shows how many species of plants and animals are in danger of getting extinct.
Today around 80.000 different species are marked on that list.

What’s destroying biodiversity?

We are! The Humans! As the human population increases every day, wild areas are getting destroyed to create farmland, housing and industrial sites.

The first step of destruction:

Deforestation. Round 30 mill. hectares of forests– that’s the geological area of Britain and Ireland – were globally lost in 2016 and round 18 mill. hectares of forests are lost each year. This also enhances Climate change.

Changes in climate throughout our planet’s history have changed life on Earth in the long run – ecosystems have come and gone and species routinely go naturally extinct.

But the rapid, manmade climate change speeds up the process, without affording ecosystems and species enough time to adapt. For example, rising ocean temperatures affect marine biodiversity and can shift vegetation zones, having global implications.
Overall, climate is a major factor in the distribution of species across the globe.

The climate change forces them to adjust. But many are not able to cope, causing them to die out.

Other major factors are overhunting, overfishing and over-harvesting! They all contribute greatly to the loss of biodiversity, killing off numerous species over the past several hundred years. For example more than 300 mammal species have been eaten into extinction since the humans .....[read full text]
