Why are great animal migrations collapsing? DW 02/12/2024
Animal migrations are remarkable feats of nature, with species traveling thousands of kilometers to find food, avoid cold winters, and reach breeding grounds.
Migratory animals face increasing threats, including habitat destruction, climate change, and illegal hunting, highlighting the need for conservation efforts. [ more ]
Western monarch butterflies overwintering in California dropped by 30% last year, researchers say
The number of western monarch butterflies overwintering in California dropped by 30% last year.
The decline in population is likely due to wet weather and habitat destruction caused by housing construction, pesticide use, and climate change. [ more ]
Western monarch butterflies overwintering in California dropped by 30% last year, researchers say
The number of western monarch butterflies overwintering in California dropped by 30% last year, likely due to heavy rainfall.
The destruction of milkweed habitat, increased pesticide use, and climate change are all contributing to the decline of western monarch butterfly populations. [ more ]
Biodiversity: Can extinctions be stopped? DW 03/05/2024
Humans are driving the sixth mass extinction by significantly increasing the extinction rate of species through activities like deforestation and pollution.
Conservation measures have been able to reverse declines in some species, but efforts may fail if the approach is not correct. [ more ]
Biodiversity: Can extinctions be stopped? DW 03/05/2024
Humans are driving the sixth mass extinction with an extinction rate pushed to around 27,000 annually.
Conservation measures, including breeding programs, environmental laws, and reserves, have helped reverse declines in some species, but are insufficient to compensate for rapid global extinction rates. [ more ]
