#Cats stalking and harassing wildlife
According to an Australia #Wildlife report, almost one third of households across the country have pet cats, equating to 5.3 million animals. Experts say 546 million small animals are killed by roaming cats each year.

‘Koala populations have depleted 62 per cent since I was born. This forest is a dunggirr (koala) hotspot, and we are in an extinction crisis. It is not ok that the NSW Forestry Corporation wants to log it.’
Activist blocking logging at Boambee State Forest near Coffs Harbour

Boambee State Forest on the western edge of Coffs Harbour, that is proposed to be part of the GKNP, is today being blocked from logging by activist Ella.

Plastic Pollution Is So Pervasive That It’s Causing a New Disease in Seabirds

Researchers coined the term “plasticosis” to describe stomach damage related to ingesting trash.

Not Winging It: Birders Hope Hard Data Will Help Save the Species They Love—and the Ecosystems Birds Depend On

Whether they’re staying for the summer or just passing through, birds are helping researchers study the environment and restore local habitats.

From #pollution to the #ClimateCrisis and wildlife #extinctions, #AnimalCruelty to human #hunger and #malnutrition. Take a closer look at almost any global challenge, and you’ll find food at its core.

In intensive farms, billions of animals are cruelly confined or bred for unnaturally fast growth or high yields. 40% of global arable land is used to feed animals instead of people – driving deforestation and massive loss of wildlife habitats.

Often, the smallest #fossil tells the best story. The #Tanzanian 🇹🇿 Drilling Project studies #fossils of #plankton and other tiny #marine organisms to better understand #climate and its impacts during periods of time much warmer than today. For example, this core was bored into #Paleocene rocks, revealing details of an #offshore #environment that existed just after one of our planet's largest mass #extinctions.

The global biomass of wild mammals
"This quantitative global view of wildlife, when contrasted for example to the mass of humanity and its livestock, can help dispel notions about the seemingly endless ubiquity of wildlife and provide a quantitative argument for the urgency of nature conservation efforts."
