Biodiversity is the variety of all species on earth. It is the different plants, animals and micro-organisms, their genes, and the terrestrial, marine and freshwater ecosystems of which they are a part. Biodiversity is both essential for our existence and intrinsically valuable in its own right.
It's important to preserve our biodiversity because of issues such as fragmentation and degradation of habitats, the spread of invasive species, unsustainable use of natural resources, climate change, and changes to the aquatic environment and water flows.
Here are some reasons why!
1. With more plants, trees and animals our soils improved and became stronger - less prone to erosion, drought and flooding.
2. We reduce the impacts of climate change and the challenges this poses on the environment and our future. Flooding, sea levels rising, drought, fires all pose huge threats to the world we live in as humans, living organisms and animals species. The extinction of a species may have unforeseen impacts, sometimes snowballing into the destruction of entire ecosystems.
3. Ecological life support—biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
4. Balance! A healthy balanced environment works best. If we remove too much of one thing, or have too much of another the whole puzzle doesn't quite work together as nature intended.
5. The world is a beautiful place, full of natural wonder, landscapes, animals and waterways. We need to preserve its existence and the habitats in which our animals, plants and organism live so that we can enjoy its abundance for generations to come.
