Answer 1

Answer:

2. Reptiles are one of many groups facing population decline. In the EU, 18% of reptile species on the IUCN Red List are considered threatened. The major cause of this is the loss and degradation of habitat, but a close second is the use of agricultural chemicals. Pesticides can have negative effects on biodiversity1

3. Ubiquitous toxins, global warming, nonnative predators, overcollection, habitat destruction and disease are key factors leading to their demise. Globally, about 20 percent of evaluated reptiles are threatened with extinction, according to the International Union for Conservation of Nature's Red List.
