Large-scale fish farm production offsets environmental gains, assessment finds

This item was filled under Climate
Industrial-scale aquaculture production magnifies environmental degradation, according to the first global assessment of the effects of marine finfish aquaculture (e.g., salmon, cod, turbot and grouper) released today. This is true even when farming operations implement the best current marine fish farming practices, according to the findings....

New evidence supports ‘Snowball Earth’ as trigger for early animal evolution

This item was filled under Climate
A team of scientists has found new evidence linking "Snowball Earth" glacial events to the rise of early animals: marine phosphorus. The researchers tracked phosphorus concentrations through Earth's history and found a pronounced spike in marine phosphorus levels in the mid-Neoproterozoic. They say phosphorus, which is essential for life, led to a spike in oxygen production via photosynthesis, facilitating the emergence of complex life on Earth....
