Tourism growth threatens global resources
Tourism has proved itself one of the most resilient global industries, shrugging off the recent financial crisis to resume healthy growth and hit new record levels. As the rise in living standards in countries such as China translates into growing appetites for international travel, tourism levels look set to continue growing. But this growth…

(Photo: electron micrograph of a blackfly with Onchocerca parasite, credit:USDA) The idea of sitting in a field and letting blackflies potentially carrying an unpleasant disease bite you sounds like a job best avoided, yet this is the way in which populations of blackflies carrying the river blindness parasite Onchocerca are monitored in Sub-Saharan Africa.

World Wildlife Day 2015

Ebola – the not so new virus
Ebola, now largely confined to Sierra Leone, Liberia and Guinea claimed more than 9300 lives in West Africa in a year. I have selected key facts & insights from February’s national symposium “Ebola: The 21st century plague?" [Royal Society of Medicine, London, UK], held by international experts handling the epidemic. Covering the history of the disease, lessons learnt from 2014, and what strategies are in place for preventing future outbreaks, there was also an explanation finally as to why a rural outbreak became a regional urban epidemic, and an understanding of the complexity of medical volunteering and running ebola treatment centres.
New study produces biofuel and animal feed from the same crop
‘First generation’ bioethanol is produced directly from food crops such as corn and sugarcane. Global production of bioethanol has been increasing in recent years due to policies in many countries that consider biofuel as a renewable alternative to fossil fuels. While it is widely recognised as means to improve future energy security, the rapid expansion…
Using lasers to map forest carbon
Forests cover approximately 4 billion hectares of the Earth's surface, equivalent to a third of it's total land area. According to the WWF, between 12-15 million hectares of forests are lost every year due to human impacts, such as deforestation. It is estimated that forest loss is responsible for around 15% of global carbon emissions.…
Insecticide threat to aquatic biodiversity highlighted in new study
Insecticides can be beneficial to humans in many ways, such as providing crop protection from disease and defoliation and as a tool used in the reduction of mosquitoes and other insects that can transmit diseases such as malaria, to humans. However, once they enter an aquatic system, the environmental costs can be very high. Just…
Why walking in groups is good for you
Despite all the government campaigns, targets and media stories about the importance of regular exercise, a high proportion of the populations of Western countries still leads a very sedentary lifestyle. Cost and availability of facilities such as gyms and sports centres shouldn’t be a factor, given the benefit that can be obtained from simply walking…
Changing attitudes to wood
Wood has many different uses, including shelter, fuel and paper to write on, as well as having a key role in maintaining a healthy planet. More recently however, the development of engineered wood for use in the construction of tall buildings has led to a new generation of ‘ply-scrapers’. So is our attitude to wood…
Is orphanage tourism fuelling child trafficking?
Of all the forms of ‘volunteer tourism’, orphanage visits or volunteering have raised the most concern. A number of charities have warned about the emotional harm that could be caused by a constant stream of volunteers who shower orphans with affection for a few hours or days, and then disappear for ever. Concerns have…
