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...

We’re all fucked, enjoy what’s left of natural beauty because it’s all going to be gone in the blink of an eye.

Humanity gets so fucking horny over the idea of alien life, meanwhile we have absolutely amazing, surreal, awe inspiring life forms ALL OVER THE PLANET. We’re living with fascinating, alien lifeforms, and we’re just watching them all go extinct while we furiously masturbate the dick of late-stage capitalism.

For all we know these creatures are the only companions we will ever know in the universe, and we’re just crossing species off the list by the thousands each year (and rapidly accelerating).

I feel like I’m drowning in despair—it’s enough to sometimes wish I was one of the fucking countless people who are just too small-minded/ignorant/selfish to care. Just blissfully reciting talking points created by rich old men, bumping and bumbling my way through life completely oblivious to the hell we’re collectively approaching.

Bro, please, trust me bro, we just need a little more carbon and it'll start getting more green. C'mon, bro, just burn a few more gallons of gas, and I swear we'll green the Sahara, bro. Listen, bro, we've never had such dangerously low carbon levels, bro, c'mon you're actually helping the environment with my profits, please, bro.

A global statistic blends greening slowly in some areas, browning faster in others. A fire can in a few hours devastate a forest in an area that became too arid, while it may take a century for a forest to grow in an area where climate improved. So while climate warming accelerates this'll get worse, but if the same climate stabilised the global vegetation cover at equilibrium might be not so bad (even if very bad in some regions). Regarding air moisture, both H~2~O and and CO~2~ pass through the same stomata in leaves, so there was some hope that plants could open these less at higher CO~2~ and thus resist drought, but as with all such effects the benefit tapers off.
Anyway all policy scenarios with any hope of staying below 2ºC, let alone 1.5ºC, include a lot of net reforestation. So we'll have to turn this around, somewhere.

Is this another positive feedback loop?
