The plains zebra is the only species of wild equid not near or on the verge of extinction. Both the Grevy's zebra and the mountain zebra are listed as endangered, along with one other species in the family Equidae. While plains zebra populations remain plentiful, their numbers diminished greatly in the last century. This is for several reasons. Humans hunt them for sport and their skins.
Glyphosate (Roundup) Linked To Cancer of the Lymph Tissue In New Study. A new review on the relationship between pesticide exposure and the risk of blood cancers in the lymph glands (lymphomas) has confirmed the existence of a link with the world's most popular herbicide glyphosate (aka Roundup).
Roundup is a systemic herbicide. That means it must be absorbed by the leaves. It moves down the plant and into the roots. This takes time. In about seven to 10 days plants sprayed with Roundup will begin turn yellow, after which they will die.
