About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

The continued destruction of nature across the planet will result in major shocks to food supplies and safe water, the disappearance of unique species and the loss of landscapes central to human culture and leisure by the middle of this century, experts have warned.

By 2050, if humanity does not follow through on commitments to tackle the five main drivers of nature loss critical natural systems could break down just as the human population is projected to peak.

The Guardian asked leading scientists, Indigenous leaders and conservationists around the world about the consequences of inaction on biodiversity loss by the middle of this century. Despite 1 million plant and animal species at risk of extinction, and in the face of wildfires, floods and extreme weather intensifying due to the climate crisis, nature conservation is increasingly becoming a part of the culture wars raging in many countries, which have spurred opposition to many environmental policies.

This is the best summary I could come up with:


The continued destruction of nature across the planet will result in major shocks to food supplies and safe water, the disappearance of unique species and the loss of landscapes central to human culture and leisure by the middle of this century, experts have warned.

Despite 1 million plant and animal species at risk of extinction, and in the face of wildfires, floods and extreme weather intensifying due to the climate crisis, nature conservation is increasingly becoming a part of the culture wars raging in many countries, which have spurred opposition to many environmental policies.

Not taking action by the middle of the century may result in extinctions, the rapid spread of invasive species (often bringing new diseases), plastic pollution on a vast scale, crashing fish populations and disappearing forests, experts from every continent have warned.

To counteract the potential loss, research indicates humanity must work to restore nature across the planet, adopt more environmentally friendly farming practices, reduce meat consumption, stop the spread of invasive species and dramatically cut the use of fossil fuels.

Dr Jean-Marc Fromentin, from the marine protection body UMR Marbec, said: “Without decisive action, the ocean’s productivity and consequently the world fish catch is set to decline sharply due to seawater warming and acidification caused by climate change.
