Flu, measles, gastro-enteritis, the list goes on. Throughout our lives, viruses regularly cross our paths. Others such as the Zika virus, H1N1 and Ebola hit the news headlines. In this book we’re given descriptions of a wide variety of viruses, how they’re transmitted and learn about the multiplication process at work. We’ll also find out why they cause illnesses and sometimes kill, how to fight them, and even how to utilise them for controlling other diseases.
Coal, gas and petroleum - resources that are not inexhaustible - produce greenhouse gases responsible for global warming. Plants could be a genuine alternative to these fossil products, at least partially, for both the energy sector and for materials and other products derived from petroleum. This work takes stock of this new chemistry known as “phytochemistry” or “biosourced chemistry”.
This work sets out the main ecological, social, economic and political issues of tropical forests. Local, national or international action instruments are recommended for each issue. This book guides the reader towards understanding of solutions frequently clubbed together under the term “sustainable forest management”. It includes FAO 2015 data on the state of tropical forests and will appeal to anyone curious to find out more about the issues of natural resources.
The French Academy of Agriculture expresses its views here on genetically-modified plants through a dozen or so key scientific, agronomic, economic, legal and sociological questions that are being discussed in society, where the answers are neither simple nor obvious.
The mechanisms of evolution are reviewed by a great museum specialist to explain simply the organisation of the living, the individual and also society as it currently stands. The latest scientific discoveries and concrete examples illustrate the comments.
The current environmental crisis is accompanied by a crisis of the biodiversity and an epidemiological crisis marked by the emergence of new infectious diseases coming from wild and domestic animals. Could there be links between biodiversity and transmission of pathogens? Do biodiversity losses increase infectious health risks? Conversely, are wild animals and the biodiversity in the broadest sense influenced by the use of antibiotics? Are the services rendered by the ecosystems - pollination by bees, for example, - threatened by pesticides? Have wild animals become, reluctantly, a sentinel for the healthiness of our environment?
In a deeply-changing world, the huge challenge of the 21stcentury is to guarantee sufficient quantities of good quality water and food for populations. Scientists, farmers and industrialists must win the innovation wager to meet this challenge. How will our food be produced, processed and marketed over the next decades. During this journey into the future, we shall explore environmentally-friendly, "sustainably productive" types of farming, the potential place for genetically modified organisms, the urgency in reducing foodstuff losses, recourse to micro-organisms and algae, even insects and the ever-improving sanitary quality of our food.
Fruit of the photosynthesis of plants, the biomass is an essential resource for humans, supplying them with food, energy and materials. With its three sources (forest, crops and waste), the energy-biomass is restricted by the production capacity of soils and its competition with its other uses. Could it therefore contribute to the growing energy needs of humanity and to the energy transition that must take place to reduce our oil and gas consumption substantially?
