Tip: For joints 1/8 inch to Â½ inch, use sanded grout. For joints up to 1/8 inch, use non-sanded grout. â¢ Before grouting, remove all of your tile spacers. Again, leaving the spacers in place and grouting over them will compromise the integrity of the grout.
The assessment, conducted by the Primate Specialist Group of the International Union for the Conservation of Nature (IUCN), concludes that 23 lemurs qualify as Critically Endangered - the highest class of threat. Fifty-two are in the Endangered classification, and a further 19 Vulnerable to extinction.
According to the IUCN, green turtles are listed as endangered, and their numbers are decreasing. Green turtles are hunted and their eggs are collected by humans, a legal practice in some countries. Green turtles are also threatened by destruction of nesting areas and foraging areas in the sea. Sometimes green turtles are accidentally caught in fishing nets, further declining their population. There are efforts to lessen the amount of turtles and eggs harvested in many countries.
