According to the report, biodiversity loss is happening at an accelerated rate, and“the risk of species extinction has worsened by almost 10 per cent over the last 25 years.”.
The risks associated with temperatures at or above 4°C include substantial species extinction, global and regional food insecurity, consequential constraints on common human activities and limited potential for adaptation in some cases(high confidence).

Soon the demand for this tool has increased so much that the Peruvian government has forbidden to extract the roots of plants, fearing theextinction of the species.
However, while this is true, the indicators for species extinctions, habitat loss, greenhouse gas emissions and resource depletion have all been negative for a prolonged period of time.
Here I present five laws derived from fossil data that describe the relationships among species extinction and longevity, species richness, origination rates, extinction rates and diversification.
The extinction of species all along the chain may mean the loss of useful genetic material or life saving cancer drugs or safer alternatives to the dangerous chemicals in use at the moment.
種の絶滅率や有害な遺伝的変異率の高さは、生命が比較的短い期間しか存在していないことを示している。
The high observed rate of extinctions of species[41] and harmful genetic mutations suggest a relatively short period for the existence of life rather than a long one.
The team determined that once 50-90 percent of small-scale ecosystems become altered, the entire eco-web tips over into a new state, characterised especially by species extinctions.
Some important cross-issue collaborations have emerged, such as climate justice, but for the most part those working on climate change don't link up with those working on poverty, toxic waste, species extinction, ethnic conflict or global trade.
Nearly 100 groups around the world-including indigenous peoples, conservation organizations, and philanthropic foundations-have endorsed the goal of protecting at least 30 percent of the planet by 2030 to address the urgent threats of climate change, habitat loss, and species extinction.

Declaring a species extinct itself can be an act of giving up, or worse- once a species is considered extinct, governments may no longer feel the need to fund protections for its habitat.
Pimm et al. review the current state of knowledge and ask what the future rates of species extinction will be, how well protected areas will slow extinction rates, and how the remaining gaps in knowledge might be filled.
While endemic and threatened species of fauna are afforded some protection by Japanese law, the habitats of the Japanese giant salamander receive no such protection, and as a result are under threat from development schemes, which have high levels of environmental impact upon the lives of these endangered and legendary amphibians.
