    About 86% of countries use more than they produce. New Zealand, despite being an advanced and wealthy country, isn’t one of those thanks to our large areas of forest and grazing land, and minimal urban area so we don’t appear on the Earth Overshoot chart.

    In the early 1980s, it took until mid-December to reach Earth Overshoot Day, calculated by working out the world’s biocapacity and dividing it by demand. Now it is in August.

    Cheers 🙂

    Thank you for that Hero42. That is a really interesting link.

    I found the OverShoot network link to be interesting as well in that it provides a calculator for our individual footprints, although i haven’t used that yet.

    On Earth Overshoot Day (Aug. 2), calculate your own Overshoot Day and #movethedate

    I found this which might interest as to what is being done here in NZ.

    Thank you Hero42, that’s another lot of information I was not aware of.
    K think that the Got’s aims are going to be very important also.

    This is a useful site to find out more about Solar and if you are more interested in saving money as well as saving the planet to see if it is cost effective

    More evidence and more bad news.

    Extreme ocean winds and wave heights are increasing around the world, researchers warn – and the worst of it is happening down under.

    Professor Ian Young and Agustinus Ribal from the University of Melbourne conducted a study over 33 years by comparing information from satellites to data collected by a global network of ocean buoys.

    Their analysis found extreme winds in the Southern Ocean have increased by 1.5 metres per second, or 8 percent, over the past 30 years. Extreme waves have increased by 30 centimetres, or 5 percent, over the same period.

    The experts warn that this could be devastating to coastal communities.

    “Although increases of 5% and 8% might not seem like much, if sustained into the future such changes to our climate will have major impacts,” Prof Young said.

    “Flooding events are caused by storm surge and associated breaking waves. The increased sea level makes these events more serious and more frequent.

    “Increases in wave height, and changes in other properties such as wave direction, will further increase the probability of coastal flooding.”

    A major United Nations report, compiled by some of the world’s leading scientists, provides evidence the planet is facing a sixth wave of extinction.

    Up to one million species are at risk of extinction, many within decades.

    The UN’s leading research body on nature, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), concludes that humanity and wildlife’s futures are at risk unless urgent action is taken to curb the loss of plants, insects and other vital parts of the planet’s life cycle.

    “There is no question we are losing biodiversity at a truly unsustainable rate that will affect human wellbeing both for current and future generations,” the chair of IPBES, Robert Watson, told The Guardian. “We are in trouble if we don’t act, but there are a range of actions that can be taken to protect nature and meet human goals for health and development.”

    Looks like Mommabear’s hope to be dead before the effects occur might be optimistic.

    We are going to have a growing army of angry young people to explain to why some of us didn’t take action when we had the chance.

    More details from the report.
    The just-published United Nations assessment – known as the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) – says nature is declining globally at rates unprecedented in human history.

    The landmark report issues an ominous warning – the rate of species extinctions is accelerating, and this will have grave impacts on people around the world.

    Humans have significantly altered three-quarters of the land-based environment and two-thirds of the marine environment.

    More than a third of the world’s land surface and nearly three-quarters of freshwater resources are devoted to crop or livestock production.

    Up to $US577 billion ($NZ872b) in annual global crops are at risk from pollinator loss.

    Plastic pollution has increased ten-fold since 1980 and up to 400 million tonnes of heavy metals, solvents and toxic sludge are dumped annually into the world’s waters.

    Since 1980, more than half of the increase in agriculture has been at the expense of intact forests.

    Only 3% of the world’s oceans were described as free from human pressure in 2014.

    Fish are being exploited as never before, with 33 percent of fish stocks harvested at unsustainable levels in 2015.

    Live coral cover on reefs has nearly halved over the past 150 years.

    Thank you Hero42. All interesting reports.
    Greta is still going strong and seems to be attracting more attention, I hope it doesn’t lead to problems for her.
    Kind regards to you all from Ted

    This mother makes me feel good about the future.

    With six kids and no car, this mom does it all by bike
