The illegal wildlife trade is the illegal trading of plants and wildlife. This illegal trading is worth an estimate of 7-23 billion [30] and an annual trade of around 100 million plants and animals. [31] In 2021 it was found that this trade has caused a 60% decline in species abundance, and 80% for endangered species. [31]
Namibia will kill more than 700 wild animals and distribute meat to those struggling with food insecurity as the country grapples with its worst drought in 100 years.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
For example, biodiversity is a source of food, medication, and materials used in industry. Recreation and tourism are also examples of human economic activities that rely on these benefits. In 2018, the WWF Living Planet Report argues that the whole global economy of US$125 trillion ultimately relies on nature. [3]
Environmental degradation, human insecurity, and social conflict frequently accompany natural resource exploitation.

For example, climate change can be viewed a threat to environmental security (see the article climate security for more nuance to the discussion.) Human activity impacts CO 2 emissions, impacting regional and global climatic and environmental changes and thus changes in agricultural output. This can lead to food shortages which will then cause ...
