Creatures of Light

By Marcelo Kawanami

Today I would like to share with you the amazing exhibition that the Canadian Museum of Nature is currently hosting on bioluminescence creatures. Bioluminescence is light produced by living organisms.

Researchers estimate that between 80 and 90 percent of deep-dwelling animals are bioluminous, creating light by mixing the pigment luciferin with luciferase, the enzyme that makes it glow. The light tends to green and blue, colors that travel far in seawater. Glowing helps attract mates, lure prey or confound predators.

This particular exhibition will be open just until November 9th 2014. For further information, check the following link:

Living Planet Report 2014

By Marcelo Kawanami

WWF has recently published is famous Living Planet Report 2014, in collaboration with the Zoological Society of London, the Global Footprint Network, and the Water Footprint Network. This 170+ pages report brings an in-depth analysis on the health of our planet and the impact of the human activity.

Covering the entire global ecosystem, the report was very focused on topics that are very relevant to Gamiing such as freshwater, marine biodiversity, and water scarcity. I separated below some key highlights from the report:

• Energy generation uses Living Planet Report 2014approximately 8 per cent of the global water withdrawals, afigure which rises to 45 per cent in industrialized countries

• The main threats to freshwater species are habitat loss and fragmentation, pollution and invasive species (Collen et al., 2014). Direct impacts on water levels or on freshwater system connectivity have a major impact on freshwater habitats

• More than 200 river basins, home to some 2.67 billion people, already experience severe water scarcity for at least one month every year

• Global freshwater demand is projected to exceed current supply by more than 40 per cent by 2030 (WRG, 2009); by 2030, almost half of the world’s population will be living in areas of high water stress (OECD, 2008)

• Energy generation uses approximately 8 per cent of the global water withdrawals, a figure which rises to 45 per cent in industrialized countries
