Threats to the arthropods
Unfortunately, some types of arthropods are on the facet of extinction, For example, ornamental tarantula. People can meet this spider only in Indian forests, because of poacher's big demand. Or another problem which can led to bad consequences. It is extiction of freshwater crabs. Their extinction connect with humans. People destroy natural places where crabs can habitate and transform many lakes and rivers for agriculture. Scientists predict that 16%, or even 65% would disappear. How can people prevent it? Nowaday, scientists only admired that this is big problem, but didn't do anything yet. So, our redactors studied this problem. We have learnt that own territory for crabs, it is very important. And many clean lacks and rivers transformed into scavenger after that how near with pond built factory. Because, many factories put their wastes in the water. So, we suggest establish filtres which will clean water in the ponds. But it is expencive and many governments could refuse from this idea, because it will influence on economic of governments badly.
