Human activity is drastically reshaping life on earth through deforestation, exploiting species and other environmental impacts.
Nowhere is this more apparent than in forests. These ecosystems house diverse plants, fungi, mammals, birds and invertebrates. From the Amazon to Indonesia, humans are cutting trees down to make room for farms, urban development and other livelihoods.that 60 percent of forests will be threatened by deforestation, forest degradation and wildfires if current trends continue.
Humans also exploit some species directly. According to the International Union Conservation of Nature, extinction threatens 85 percent of sturgeons, a group of large freshwater fish that are harvested for their roe. If the current trend continues, many sturgeon species could follow the morbid example of the carrier pigeon, which was hunted to extinction by European American settlers.Ultimately, complex and interweaving factors cause all mass extinctions.
“It’s important to think about the overlap of these broad categorizations,” says Wollmuth. “For instance, climate change can lead to habitat alteration or disease.” Though the causes of the sixth mass extinction are somewhat opaque, one potential solution is to limit global warming. According to the IPCC, it is possible to limit global warming to about 35 degrees
