A bit of both actually.
We regulate rivers, we pollute, we build farms, villages and cities - which doesn't help the hippo.
But we also establish nature reserves and game parks, employ wildlife wardens and rangers - which does help the hippo.
Overall though the hippo would probably have done better if there weren't any humans at all.
While technically a vulnerable, not endangered, species, their preservation is dependent on a number of factors, such as improved economic conditions in the countries which they inhabit in an attempt to reduce the need to resort to hunting them for meat for food and ivory for money. Economic prosperity would in turn afford those countries a greater capacity to prevent rampant habitat destruction, which many now cannot do. In addition to this, contributing donations to worthy animal and habitat preservation charities (such as the WWF and others), funds can be collected to begin initiatives targeting specific habitats, species or populations of species that would otherwise go unaddressed and potentially destroyed/extinct.
humans don't harm hippos,but some people do to use their skin
humans are destroying the hippo's habitat
Preserves
If we all did what I do, pandas would have been extinct a long time ago.
Hippopotamus are endangered due to the exploitation and habit loss (mainly due to heavy clearning of forest area). They are hunted illegally for meat.
People are trying to find the pygmy hippos a suitable habitat. But, war in the area is preventing people from finding a suitable habitat for pygmy hippos. Most pygmy hippos live in zoos. In zoos the pygmy hippos are safe from hunters and natural predators. Pygmy hippos have plenty of food and water in the zoos. The zoo keepers breed the pygmy hippos. Also, some people are keeping pygmy hippos as pets.
they are doing nothing at all to help the penguins to not be extinct
helping them
Kiwis are not extinct. They are endangered. Extinct means they do not exist anymore.
People are trying to prevent tiger salamanders from becoming extinct because you are stupid and p.s I HATE JUSTIN BEIBER
they trie to work out every day doing the hippy to get in shape.
Bald Eagles are not extinct.
Stop polluting the waters and building buildings
The cougar is not extinct. It is doing well over most of it's range, with the Florida race the only endangered one.
You can adopt whales,dolphins and sharks. Doing so you would be helping t stop certain species becoming extinct. if you adopt a whale you will help stop some species become extinct
