Living Planet Report

Living Planet Report
The Living Planet Report is the world's leading, science-based analysis on the health of our planet and the impact of human activity. Knowing we only have one planet, WWF believes that humanity can make better choices that translate into clear benefits for ecology, society and the economy today and in the long term. This latest edition of the Living Planet Report is not for the faint-hearted. One key point that jumps out is that the Living Planet Index (LPI), which measures more than 10,000 representative populations of mammals, birds, reptiles, amphibians and fish, has declined by 52 per cent since 1970. Put another way, in less than two human generations, population sizes of vertebrate species have dropped by half. These are the living forms that constitute the fabric of the ecosystems which sustain life on Earth – and the barometer of what we are doing to our own planet, our only home. We are using nature’s gifts as if we had more than just one Earth at our disposal.

Ecological footprint (Human) ecological footprint is a measurement of anthropogenic impact on earth. Two fields of science scope human impact on Earth; they are geospheric and biospheric sciences. Human activity is measured through ecological footprint research. Our activity is now the leading cause of climate change. [1] Our impact is now threatening total global collapse. [2] [3] Since the 1950s the human footprint has grown so massive that it has caused Earth to enter into an new geological epoch called The Anthropocene.[4] Underground river 'Rio Hamza' discovered 4km beneath the Amazon An aerial view of the Amazon river.

Ecological Footprint - Home Please note that this website will be shut down at the end of 2013. You can find other ecological footprint calculators at the Global Footprint Network and the WWF-Australia websites. People often get disillusioned by sustainability, saying it is too complicated to understand, when in actual fact it is really quite simple. Think of it this way: every human activity consumes resources from the planet and produces waste that the planet must then deal with. We can even measure how close we are to a sustainable society. This is where the Ecological Footprint has a major role to play.

WikiLeaks reveals China's failure to measure dangerous pollution China has not measured data on the most dangerous types of air pollution because it is afraid of the political consequences, according to US diplomatic cables. This assessment, which comes to light as the government prepares to upgrade its air quality monitoring system, was among the central findings of cables from the US consulate in Guangzhou that were relased on Wednesday by WikiLeaks. Diplomats based in the industrial heartland of Guangdong – known as the workshop of the world and also one of the worst areas for acid rain and other pollution – looked in detail at monitoring systems and health impacts in 2006. Based on research by local scientists, the consulate noted in a cable dated 16 August that small-particulate matter known as PM2.5, was five to 10 times higher than suggested by World Health Organisation guidelines. PM2.5 was not the only problem. The state media reported on Thursday that a new index would soon be introduced.

Ecological Footprint Ecological Footprint What Is the Ecological Footprint? The Ecological Footprint is rooted in the fact that all renewable resources come from the earth. It accounts for the flows of energy and matter to and from any defined economy and converts these into the corresponding land/water area required for nature to support these flows.

Climate change could displace up to a quarter of a billion people DW: In Europe we're seeing the arrival of hundreds of thousands of refugees, mostly from war-torn countries. Some are calling it a "migration crisis," but is this the new normal? Is this the kind of mass migration that climate change could cause? Scott Leckie: Well, we hope that's not the new normal and we believe, through what we've done in 15 or 20 different countries, that most people who will leave their homes because of climate change will aim initially to stay within the borders of their own country. China's love affair with the car shuns green vehicles A traffic jam along a main road in central Beijing. Photograph: David Gray/Reuters Beijing used to be famous for the millions of bicycles thronging its streets. But it is the success of the motor car there and in other Chinese mega-cities that has now tipped the number of cars in the world over the 1bn mark. According to a report by the trade journal Ward's, 35m new cars and lorries were sold worldwide last year – the second-biggest increase ever recorded. That is 95,500 extra vehicles being added to the global traffic jam every day.

Ecological Footprint 2.0 by Worldchanging Intern, Alex Lowe: To understand the subtleties and difficulties in ecological footprinting, think of accounting. In the past few years, Enron's collapse and the scandals that surrounded WorldCom gave people a small glimpse into the intricacies of accountancy. What's Really Warming the World? Climate deniers blame natural factors; NASA data proves otherwise Climate scientists tend not to report climate results in whole temperatures. Instead, they talk about how the annual temperature departs from an average, or baseline. They call these departures "anomalies." They do this because temperature anomalies are more consistent in an area than absolute temperatures are. For example, the absolute temperature atop the Empire State Building may be different by several degrees than the absolute temperature at New York’s LaGuardia Airport.
