Some misguided people, today, who may call themselves "pronatalist", and who look at future predictions of negative population growth (meaning that population will decrease in the future, instead of continuing to increase), and see this as a problem, are wrong or are not thinking clearly. Some of them may believe that African and Arab and Asian populations are in the process of "replacing" or at least are overtaking the Caucasian, European-based ethnicities that have traditionally been the majority of the population in countries like the US, the UK, Europe, Canada, Australia and New Zealand; and they are right - this is indeed happening, as is the Hispanicization of the US population because of such massive immigration. And they are right to be concerned about this. In a century there may be no nations left on Earth where Caucasians of European ancestry are the majority of the population if immigration is not stopped. And this is a problem. There will be African majority countries, Asian majority countries, Arab majority countries, Hispanic majority countries, but there will not be any Caucasian of European ancestry majority countries left if we do not take action now.

UN climate report: Scientists release 'survival guide' to avert climate disaster

Scientists from the Intergovernmental Panel on Climate Change met in Switzerland where glaciers are melting

UN chief Antonio Guterres says a major new report on climate change is a "survival guide for humanity".

Clean energy and technology can be exploited to avoid the growing climate disaster, the report says.

Australia has suffered a litany of natural disasters in recent years including historic bushfires

Australia's environment is in a shocking state and faces further decline from amplifying threats, according to an anticipated report.

The survey of Australia's ecological systems - conducted every five years - found widespread abrupt changes.

These can be blamed on climate change, habitat loss, invasive species, pollution and mining, it said.

The threats are not being adequately managed - meaning they are on track to cause more problems.
