Agriculture Agriculture is the science, art and activity of cultivating plants and domesticating animals mainly for food and products that sustain and enhance human life.

What can we do to protect biodiversity? What can I do as an individual to protect biodiversity? Can we allow nature to regenerate without intervention? How do we decide what is worth saving or putting our efforts into protecting? Up Introduction What is biodiversity? Acknowledgements Down.
Introduction At its simplest, biodiversity describes life on Earth — the different genes, species and ecosystems that comprise the biosphere and the varying habitats, landscapes and regions in which they exist.
What is biodiversity? Read the full answer. We regularly hear of new species being discovered - does that not offset the loss of existing species? Every year thousands of previously unknown species are discovered, described and named.
The UK boasts more than 70, known species of animals, plants, fungi and microorganisms. Humanity impacts the planet's biodiversity in multiple ways, both deliberate and accidental. Since the middle of the 20th century, the human population has grown dramatically. Acknowledgements Find the main authors and reviewers of the questions and answers on biodiversity. See more.

Ever more people need ever more food. Agriculture deserves a special mention here as it is a primary driver of habitat destruction, climate change and pollution.
In order to meet the unsustainable consumption patterns of the Global North and feed our huge population, humanity has developed agricultural systems which rely on monocultures, artificial fertilisers and pesticides. Monocultures are increasingly susceptible to disease so require widespread pesticide use which destroys insect populations. Intensive farming leads to soil depletion and runoff from farms pollutes water bodies and causes harmful algal blooms and the collapse of fish stocks. Ever more people means ever more travel.
Human travel across the world has a very large emissions footprint but it has also allowed the spread of invasive species, both accidental and intentional. As a consequence of the introduction of non-native species to some areas, such as rabbits and cats in Australia, goats on St. Helena, and American mink in Great Britain, we have put many vulnerable ecosystems at risk, threatening native species and diminishing biodiversity.

The Sixth Mass Extinction Since life appeared on Earth, there have been several mass extinctions in which many species were wiped out because of catastrophic climate change, volcanic activity, the impact of an asteroid or other reasons we have not yet discovered.
Habitat destruction Ever more people need ever more space. Overexploitation Ever more people need ever more things. It is also home to a population of more than , people who must survive on the resources available in the corridor, not the park.
When the project began, rates of childhood vaccination in the Monkoto corridor were among the lowest in the country, while rates of malnutrition were among the highest, according to a WWF report. In response, WWF helped the Monkoto communities put in place legally binding land zoning plans and promote better land use management. The partners paid special attention to women farmers. Because women have an intense interest in sustaining natural resources to keep their children healthy, said Honzak, it is important to increase their capacity to make informed decisions about nutrition and involve them in land-use planning and governance.
The project made significant progress toward those ends. WWF also provided women and their families with reproductive health services. By , the project consistently saw new family planning users each month. According to Honzak, this kind of integrated effort can serve as an example for conservation efforts around other at-risk ecosystems. And in turn, enabling women to choose the size of their families and the spacing of their births helps ensure a more sustainable growth rate and reduce direct pressure on surrounding habitats.
