The World Wildlife Fund’s Living Planet Report 2018 has released its latest document that provides a comprehensive view of the Earth’s health – and it’s depressing. Between 1970 and 2014, populations of mammals, birds, fish, reptiles, and amphibians have, on average, declined by 60 percent. This plunge in the size of populations of vertebrate animals is the result of human modification of natural landscapes and overexploitation, the report notes.
The agriculture sector is facing significant challenges as it looks to the future. Approximately one in nine people on earth don't have enough food to live healthy lives, and the world's population is expected to grow from around 7.5 billion to almost 10 billion by 2050. Natural resources are already stressed, and climate change is threatening to worsen environmental challenges.
Air pollution takes a year off the average global life expectancy according to study published in the journal Environmental Science & Technology Letters.The study which particularly looked at distribution of a particulate matter called PM2.5 across the globe and its effects on overall global life expectancy found that for those living in the US and the UK, life expectancy drops to an average of four months - but for those living in Asia and Africa, the situation is even worse.
Blockages in the global air currents called the jet streams could explain why we experience strange and sometimes deadly weather pattern. The jet stream has a capacity, and when it’s exceeded it, blockages form that are similar to traffic jams can occur.
A study at Virginia Tech has found that mosquitoes can rapidly learn and remember the smells of hosts. Delicious-smelling individuals are usually the preferred targets, but swatting at them or performing other defensive behaviours – can teach them to stay away, researchers say. "Unfortunately, there is no way of knowing exactly what attracts a mosquito … Continue reading Mosquitoes Target Delicious-Smelling Individuals – But Swatting Teaches Them To Stay Away (For Days)
Through direct satellite observation, scientists have for the first time shown that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion.
From discovering two neutron stars collisions and a new form of matter called excitonium to creating trees that glow and using magnetic fields to control physical movements in mice, here's look back at the toughest, biggest and hottest science of 2017.
Researchers have for the first time recorded mysterious ‘hum’ generated by Earth’s movement - using seismic instruments on the bottom of the ocean. The first attempt to detect this low-frequency vibrational signal was made in 1959, but it wasn’t until 1998 that researchers were able to prove it exists.
Environmental pollution - from filthy air to contaminated water - is causing more deaths annually than all war and violence combined. According to a study published in the journal the Lancet, pollution around the world now contributes to at least one out of every six premature deaths (roughly 9 million), which is more than smoking, hunger or natural disasters, and more than AIDS, tuberculosis and malaria combined.
