Deaths attributed directly to climate change cast pall over penguins
A new long-term study reveals that heat waves and drenching rainstorms — direct results of climate change — are killing penguin chicks from the world’s largest colony of Magellanic penguins. The dangerous age is when the chicks are too big to be protected by their parents, but too young to have grown waterproof feathers. Without waterproof feathers, they can die of hypothermia during extreme downpours, and they can’t take a cooling dip in the water during heat waves. This study is the first to show the impact that climate change is having on chick survival and reproductive success. Over the 27-year period, 65 percent fo chicks died per year, 40 percent as a result of starvation. Climate change was responsible for an average of seven percent of chick deaths, but some years it was the leading cause.
Mexico bans fishing for Great white sharks
Earlier this week, the Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food established a permanent ban on fishing for great white sharks in Mexican waters. The new rule states that all white sharks caught incidentally during recreational or commercial fishing must be released immediately.
Walmart changes its seafood policy
Before the change, Walmart only sold fish in its stores that was certified by the Marine Stewardship Council (MSC) or an ‘equivalent’. Many in the Alaskan salmon industry felt this policy was unfair because there is no exact equivalent to the MSC certification. Walmart wouldn’t accept their seafood even though they are committed to sustainability. Now, Walmart has revised its policy to incorporate certifications that meet the principles set by The Sustainability Consortium (TSC).
