Global Warming: We’re Using Too Much Sun
IF only those humans would hurry up and die it would better for the rest of us:
HUMANS are just one of the millions of species on Earth, but we use up almost a quarter of the sun’s energy captured by plants – the most of any species.
The human dominance of this natural resource is affecting other species, reducing the amount of energy available to them by almost 10 per cent, scientists report.
Researchers said the findings showed humans were using “a remarkable share” of the earth’s plant productivity “to meet the needs and wants of one species”.
They also warned that the increased use of biofuels – such as ethanol and canola – should be viewed cautiously, given the potential for further pressure on ecosystems.
The scientists, from Austria and Germany, who publish their results today in the journal of the Proceedings of the National Academy of Sciences, analysed data on land use, agriculture and forestry from 161 countries, representing 97 per cent of the world’s land mass.
Can we eat each other?
