One of the greatest threats to biodiversity is the fragmentation or breaking apart of habitats. Climate change, volcanic eruptions and other geological processes can gradually modify the area in which a species finds food, shelter, and mates. By natural selection and adaptation, speciation occurs, adding to the richness of life. Conversely, human activities of deforestation, agriculture and urbanisation have accelerated habitat loss to such a degree that species are unable to adapt to the changes, leading to ecosystem decay and, ultimately, extinction.

Oryza sativa, or rice, is the staple food of more than half the world’s population and supports the livelihoods of around 145 million households. Since its domestication thousands of years ago, rice has played an essential role in shaping civilisations. However, present-day practices of rice cultivation may harm the planet's climate, shows a recent study conducted in India.
Global incidences of disease outbreaks such as Ebola, SARS, Avian influenza, etc., are increasing with over sixty percent of infectious human diseases being of zoonotic or animal origin. Human infections and fatalities occur only when zoonotic pathogens spill over from animals, upon attainment of certain specific parameters. In most cases animals, including wildlife, act as reservoirs of these pathogens are are not necessarily affected by the disease. Consequently, one would feel that animals are responsible for this disease transmission.
Researchers from the National Centre for Biological Sciences, Bengaluru, have shown that grass-fuelled fires and seasonal drought, which are the characteristics of savannas, are also observed in the dry deciduous “forests” in India. These findings add to a growing body of evidence that these systems are, in fact, savannas.
Over two-thirds of the Earth’s surface is covered with water, with nearly 97% of this being in the oceans. Oceans are home to amazing creatures—from microscopic phytoplankton which produce most of the Earth’s oxygen, to gigantic whales which take your breath away. World Wildlife Day is celebrated each year on March 3rd to celebrate and raise awareness about the diverse wildlife on our planet. The theme for 2019 is “Life below water: for people and planet" which aligns with goal 14 of the United Nations Sustainable Development Goals, i.e.
