US sprinter Sha Carri Richardson will be missing the Tokyo Olympics because she tested positive for marijuana during the US Track & Field trials. With cannabis legal in many states across America, why is it still outlawed in sports?
With her flowing tangerine orange hair, killer smile and lightning speed, Sha Carri Richardson was unmissable in the lead-up to the Olympic Games.
Considered the sixth-fastest woman in history, with a best-ever time for the 100m of 10.72, the Texas sprinter was expected to be a major contender for the Gold medal in Tokyo.

Global Water Reservoirs Release Higher Greenhouse Gases than Previously Believed
Written by AZoCleantechJun 2 2021
According to a new study, per-area greenhouse gas emissions from the global water reservoirs are about 29% higher than proposed by earlier studies, but practical measures could be adopted to mitigate that effect. The study has been published in the
Global Biogeochemical Cycles journal.
Overall, the researchers found the world’s water reservoirs are annually producing methane, carbon dioxide, and other greenhouse gases in an amount roughly equivalent to 1.07 gigatons of carbon dioxide. Image Credit: Washington State University.
As per the analysis performed by scientists from Washington State University (WSU) and the University of Quebec at Montreal, most of the increased emissions arise from methane degassing, which was not previously taken into account. Methane degassing is a process in which the gas travels via a dam and bubbles up downstream.

Global Biogeochemical Cycles shows per-area greenhouse gas emissions from the world s water reservoirs are around 29% higher than suggested by previous studies, but that practical measures could be taken to help reduce that impact.
Much of the increase in emissions comes from previously unaccounted for methane degassing, a process where methane passes through a dam and bubbles up downstream, according to the analysis by Washington State University and University of Quebec at Montreal scientists.
