Chlamydia could make koalas extinct. Can a vaccine save them in time?

On the table, unconscious and stretched out on a pillow, Joe Mangy looks deceptively peaceful. The koala's watery, red-rimmed eyes are the only sign of the disease at war with his body.

Tubes snarl out of a mask covering his face as a vet tech listens to his chest with a stethoscope. He is not healing as well as they had hoped.

Industrial wastelands to wildlife oases: Five nature wins that have actually worked:

World leaders are gathering in Cali, Colombia, to agree ways to save species from extinction and restore nature. Here are five powerful solutions to halt biodiversity loss.

There's a treasure trove of ways to save species in decline, and restore their habitats so they can live safely. In a healthy state, rich and biodiverse habitats can replenish our water, air, soil and reduce the risk of dangerous contagious diseases.

A recent, rapid heating of the world's oceans has alarmed scientists concerned that it will add to global warming.

This month, the global sea surface hit a new record high temperature. It has never warmed this much, this quickly.

Scientists don't fully understand why this has happened.

But they worry that, combined with other weather events, the world's temperature could reach a concerning new level by the end of next year.

Experts believe that a strong El Niño weather event - a weather system that heats the ocean - will also set in over the next months.

The researchers studied more than 600 species of birds and mammals

Ambitious targets to halt the decline in nature may already be slipping out of reach, a study suggests.

Scientists say the effects of climate change and habitat loss on animal populations have been underestimated.

They say bringing back wildlife may take longer than expected and that unless we act now global biodiversity targets will be out of reach.

In December almost 200 countries agreed to halt the decline in nature by the end of the decade.

Today, In 2023, Humanity is facing a catastrophic human-induced climate crisis which seriously threatens our very survival. 

Fundamentally, Humanity is faced with this climate crisis for a few principal reasons, which are important to understand in order to advocate the best solutions.

1. Pollution (including that of overpopulated species, which can be seen from the point of view of Earth as a form of toxic pollution) does not recognize national boundaries and borders while Earth is subdivided politically into self-regulating nation-states, which regulate, or fail to regulate, pollution and population for their own people and territories.
